82-517: The most famous revolvers manufactured by Charter Arms are the .44 Special Bulldog and .38 Special Bulldog Pug. Douglas McClenahan, a young gun designer who had previously worked for Colt , High Standard , and Sturm, Ruger founded Charter Arms in 1964 to produce handguns . The factory was located in Bridgeport, Connecticut , and its first revolver was a five-shot model called the "Undercover", chambered for .38 Special. McClenahan's innovation

164-429: A "big bore" caliber. The Bulldog has no sharp edges to contend with when carrying the weapon in a holster or a pocket. The Bulldog is a solid-framed traditional double-action revolver with a five-round cylinder which can be opened by pushing a release slide on the left of the gun, or in the original model by pulling the ejector rod. It features a concave sight . Its trigger pull, in both single and double-action modes,

246-964: A common ammunition feed. Famous revolver models include the Colt 1851 Navy Revolver , the Webley , the Colt Single Action Army , the Colt Official Police , Smith & Wesson Model 10 , the Smith & Wesson Model 29 of Dirty Harry fame, the Nagant M1895 , and the Colt Python . Although largely surpassed in convenience and ammunition capacity by semi-automatic pistols , revolvers still remain popular as back-up and off-duty handguns among American law enforcement officers and security guards and are still common in

328-685: A completely blocked hammer system so that the gun cannot fire unless the trigger is held in full rear position. In addition to reintroducing the .38 Special Undercover and the .44 Special Bulldog, Charter 2000 produces revolvers chambered for .22 Long Rifle/.22 Magnum (the Pathfinder), .357 Magnum (the Mag Pug) and .38 Special (the Off-Duty and the Police Bulldog). In 2005, Charter 2000 announced that it would be filing for bankruptcy, blaming

410-478: A cylinder of five shots. As of 2007 , Charter Arms only offers its 14420, 74420 and 74421 versions. Charter's Police Undercover could be considered a Bulldog variant because it is produced with the same frame model but its caliber is different and it was built to resemble the Undercover by Charter.

492-584: A double action revolver to compete with European manufacturers was the Colt Model 1877, which earned lasting notoriety for its complex, expensive, and fragile trigger mechanism, which in addition to failing frequently, also had a heavy trigger pull. In 1889, Colt introduced the Model 1889 , the first double action revolver with a "swing-out" cylinder, as opposed to a "top-break" or "side-loading" cylinder. Swing-out cylinders quickly caught on, because they combined

574-456: A few times since 1992, when Charter Arms, the original manufacturer, went bankrupt. Sometime later, manufacturing began again under the Charco (descendant company of Charter Arms) trademark. This company also filed bankruptcy, and the models produced during this period showed obvious production flaws. It was produced again by Charter 2000; this company, which failed also, improved the weapon with

656-405: A flick of the wrist can actually cause the crane to bend over time, throwing the cylinder out of alignment with the barrel. Lack of alignment between chamber and barrel is dangerous, as it can impede the bullet's transition from chamber to barrel. This causes higher pressures in the chamber, bullet damage, and the potential for an explosion if the bullet becomes stuck. The shock of firing can exert

738-423: A full one. In many of the first generation of cartridge revolvers (especially those that were converted after manufacture), the base pin on which the cylinder revolved was removed, and the cylinder taken out from the revolver for loading. Most revolvers using this method of loading are single-action revolvers, although Iver Johnson produced double-action models with removable cylinders. The removable-cylinder design

820-539: A great deal of stress on the crane, as in most designs the cylinder is only held closed at one point, the rear of the cylinder. Stronger designs, such as the Ruger Super Redhawk , use a lock in the crane as well as the lock at the rear of the cylinder. This latch provides a more secure bond between cylinder and frame, and allows the use of larger, more powerful cartridges. Swing-out cylinders are not as strong as fixed cylinders, and great care must be taken with

902-480: A one-piece barrel, front sight, and ejector-shroud assembly. The original model had no ejector-shroud, and the aluminum front sight was soldered to the barrel. In June 2007, a version of the Bulldog with new features began to be produced by another company named Charter Arms, but this time was distributed by MKS Supply. The Bulldog was used by the serial killer David Berkowitz aka "The .44 Caliber Killer" and

984-440: A partnership (S&W), then developed and manufactured a revolver chambered for a self-contained metallic cartridge. In 1993, U.S. patent 5,333,531 was issued to Roger C. Field for an economical device for minimizing the flash gap of a revolver between the barrel and the cylinder. A revolver has several firing chambers arranged in a circle in a cylindrical block; one at a time, these chambers are brought into alignment with

1066-418: A repeating rifle, such as lever-action , had been developed. Loading a cylinder in this manner was a slow and awkward process and generally could not be done in the midst of battle. Some soldiers avoided this by carrying multiple revolvers in the field. Another solution was to use a revolver with a detachable cylinder design. These revolvers allowed the shooter to quickly remove a cylinder and replace it with

1148-540: A revolver is by means of the swing-out cylinder . The first swing-out cylinder revolver was patented in France and Britain at the end of December in 1858 by Devisme. The cylinder is mounted on a pivot that is parallel to the chambers, and the cylinder swings out and down (to the left in most cases). An extractor is fitted, operated by a rod projecting from the front of the cylinder assembly. When pressed, it will push all fired rounds free simultaneously (as in top-break models,

1230-575: A shot, the user would raise their pistol vertically while cocking the hammer back for their next shot, so the fragments of the burst percussion cap would fall clear of the weapon and not jam the mechanism. Some of the most popular cap-and-ball revolvers were the Colt Model 1851 "Navy" model, 1860 "Army" model , and Colt Pocket Percussion Revolvers , all of which saw extensive use in the American Civil War . Although American revolvers were

1312-621: A single axis. A matchlock revolver with a single barrel and four chambers held at the Tower of London is believed to have been invented some time in the 15th century. A revolving three-barrelled matchlock pistol in Venice is dated from at least 1548. During the late 16th century in China, Zhao Shi-zhen invented the Xun Lei Chong , a five-barreled musket revolver spear. Around the same time,

1394-517: A time as they rotated the cylinder to line each chamber up with the side-mounted loading gate. Smith & Wesson followed seven years later with the Hand Ejector, Model 1896 in .32 S&W Long caliber, followed by the very similar, yet improved, Model 1899 (later known as the Model 10), which introduced the new .38 Special cartridge. The Model 10 went on to become the best selling handgun of

1476-413: Is a repeating handgun with at least one barrel and a revolving cylinder containing multiple chambers (each holding a single cartridge ) for firing. Because most revolver models hold up to six cartridges, before needing to be reloaded, revolvers are commonly called six shooters or sixguns . Due to their rotating cylinder mechanism, they may also be called wheel guns . Before firing, cocking

1558-475: Is considered one of the major advancements in revolver history because the frame was previously always metal alloy and mostly a one-piece design. Another 21st century development in revolver technology is the Chiappa Rhino , a revolver introduced by Italian manufacturer Chiappa in 2009, and first sold in the U.S. in 2010. The Rhino, built with the U.S. concealed carry market in mind, is designed so that

1640-426: Is employed in some modern "micro-revolvers" (usually chambered in .22 rimfire and small enough to fit in the palm of the hand) to simplify their design. Later single-action revolver models with a fixed cylinder used a loading gate at the rear of the cylinder that allowed insertion of one cartridge at a time for loading, while a rod under the barrel could be pressed rearward to eject a fired case. The loading gate on

1722-429: Is exposed at a time to the loading gate. In a top-break revolver, the frame is hinged at the bottom front of the cylinder. Releasing the lock and pushing the barrel down exposes the rear face of the cylinder. In most top-break revolvers, this act also operates an extractor that pushes the cartridges in the chambers back far enough that they will fall free, or can be removed easily. Fresh rounds are then inserted into

1804-510: Is in doubt, as similar designs were patented in the same year by Artemus Wheeler in the United States, and by Cornelius Coolidge in France. Samuel Colt submitted a British patent for his revolver in 1835 and a U.S. patent (number 138) on February 25, 1836, for a Revolving gun , and made the first production model on March 5 of that year. Another revolver patent was issued to Samuel Colt on August 29, 1839. The February 25, 1836, patent

1886-565: Is manually driven and can be cocked either by the user using the thumb to directly pull back the hammer (as in single-action ), or via internal linkage relaying the force of the trigger-pull (as in double-action ), or both (as in double-action/single-action ). Some rare revolver models can utilize the blowback of the preceding shot to automatically cock the hammer and index the next chamber, although these self-loading revolvers (known as automatic revolvers , despite technically being semi-automatic ) never gained any widespread usage. Though

1968-473: Is not safe to do so, due to differences in cartridge pressures and the fact that .22 WMR does not shoot a "heeled" bullet, along with differences in rim diameter that can allow high pressure gases to escape behind the cartridge and seriously injure the user. However, some .22 revolvers come with interchangeable cylinders so that .22 Long Rifle can be shot from a .22 WMR revolver. In 1996, the Medusa Model 47

2050-431: Is not very dependent on lubrication for proper firing. Additionally, in the case of double-action-only revolvers there is no risk of accidental discharge from dropping alone, as the hammer is cocked by the trigger pull. However, the revolver's clockwork-like internal parts are relatively delicate and can become misaligned after a severe impact, and its revolving cylinder can become jammed by excessive dirt or debris. Over

2132-493: Is quite light. If a large quantity of residue piles up inside the revolver because of heavy usage, the cylinder crane's axle screw can be removed and the cylinder pulled out from the gun for cleaning. Most critics believe the best use for the Bulldog is self-defense. The accuracy of the Bulldog is aided by its trigger pull. According to reviews, it is more accurate than expected for a revolver of its size and type but probably not enough to be called an "accurate" weapon. When

2214-412: Is superior ergonomics, particularly for users with small hands. A revolver's grip does not hold a magazine, and it can be designed or customized much more than the grip of a typical semi-automatic. Partially because of these reasons, revolvers still hold significant market share as concealed carry and home-defense weapons. A revolver can be kept loaded and ready to fire without fatiguing any springs and

2296-485: The .41 Remington Magnum Mag Pug and the .45 Colt Bulldog XL. Charter Arms Bulldog The Bulldog is a 5-shot traditional double-action revolver designed by Doug McClenahan and produced by Charter Arms . It was introduced in 1973. The Bulldog has been available for the .44 Special and .357 Magnum cartridges . It was a top-selling gun during the 1980s and it is considered to be Charter Arms' trademark weapon. It has been produced by four companies since it

2378-737: The .45 Colt , used in the Colt revolver of the Wild West . Introduced in 2003, the Smith & Wesson Model 500 is one of the most powerful revolvers, utilizing the .500 S&W Magnum cartridge. Because the rounds in a revolver are headspaced on the rim, some revolvers are capable of chambering more than one type of ammunition. Revolvers chambered in .44 Magnum will also chamber .44 Special and .44 Russian , likewise revolvers in .357 Magnum will safely chamber .38 Special , .38 Long Colt , and .38 Short Colt ; while revolvers in .22 WMR can chamber .22 Long Rifle , .22 Long , and .22 Short , it

2460-465: The Belgian gunsmith Mariette invented a hammerless pepperbox with a ring trigger and turn-off barrels that could be unscrewed. In 1836, American Samuel Colt patented a popular revolver which led to the widespread use of the revolver. According to Colt, he came up with the idea for the revolver while at sea, inspired by the capstan , which had a ratchet and pawl mechanism on it, a version of which

2542-764: The Beretta M9 and the SIG Sauer M17 , especially in circumstances where faster reload times and higher cartridge capacity are important. In 1815, (sometimes incorrectly dated as 1825) a French inventor called Julien Leroy patented a flintlock and percussion revolving rifle with a mechanically indexed cylinder and a priming magazine. Elisha Collier of Boston, Massachusetts, patented a flintlock revolver in Britain in 1818, and significant numbers were being produced in London by 1822. The origination of this invention

2624-462: The Chiappa Rhino (.357 Magnum, 9×19mm , .40 S&W , or 9×21mm ) except for the 2" and 3" models, respectively. However, certain revolvers, such as the Taurus Judge and Charter Arms revolvers, can be fitted with accessory rails. Revolvers most commonly have 6 chambers, hence the common names of "six-gun" or "six-shooter". However, some revolvers have more or less than 6, depending on

2706-455: The Ruger LCR , Smith & Wesson Bodyguard 38, and Taurus Protector Polymer. The new design incorporates polymer technology that lowers weight significantly, helps absorb recoil, and is strong enough to handle .38 Special +P and .357 Magnum loads. The polymer is only used on the lower frame and is joined to an upper frame, barrel, and cylinder that are made of metal alloy. Polymer technology

2788-674: The Single Action Army , the "Colt .45" (not to be confused with Colt-made models of the M1911 semi-automatic ), and "the Peacemaker", one of the most famous handguns ever made. This popular design, which was a culmination of many of the advances introduced in earlier weapons, fired 6 metallic cartridges and was offered in over 30 different calibers and various barrel lengths. It is still in production, along with numerous clones and lookalikes, and its overall appearance has remained

2870-528: The "Son of Sam" who was responsible for a series of attacks and murders in New York City during 1976–1977 (before he was caught due to an outstanding parking violation). The name “Bulldog” was an homage to the original Webley revolvers of the same name. Like most Charter Arms weapons, the Bulldog is a relatively inexpensive yet serviceable, no-frills, snubnosed revolver . It was designed to be concealed easily because of its small size, yet also fire

2952-566: The 20th century, at 6,000,000 units, and the .38 Special is still the most popular chambering for revolvers in the world. These new guns were an improvement over the Colt 1889 design since they incorporated a combined center-pin and ejector rod to lock the cylinder in position, whereas the Colt 1889 did not use a center pin and the cylinder was prone to move out of alignment. Revolvers have remained popular in many areas, although for law enforcement and military personnel, they have largely been supplanted by magazine-fed semi-automatic pistols , such as

3034-461: The 9mm, .40 S&W, and .45 ACP without the need for moon clips. Initially, the revolver was to ship in early spring, however, reported problems with the patents delayed the introduction. Charter Arms set a release date of April 2009 for the CARR. However, Charter Arms missed this deadline, and company representatives suggested a release date of "late July" of 2009. The CARR, which was subsequently called

3116-589: The American private sector as defensive, sporting, and hunting firearms. In the development of firearms , an important limiting factor was the time required to reload the weapon after it was fired. While the user was reloading, the weapon was useless, allowing an adversary to attack the user. Several approaches to the problem of increasing the rate of fire were developed, the earliest involving multi-barrelled weapons which allowed two or more shots without reloading. Later weapons featured multiple barrels revolving along

3198-599: The Charter design and mark were resurrected two years later by Nick Ecker and two other investors, who started the company back up under the name "Charter 2000", moving operations to Shelton, Connecticut . Basing their new line of weapons on the basic Charter Arms design, the new company has made a few improvements such as the use of a one-piece barrel and front sight. The one-piece barrels of the new models are machined with eight grooves instead of six for higher velocity, flatter trajectory and better accuracy. The new models feature

3280-568: The Pitbull, finally reached production in August 2011. The first Pitbull models had a 2.3" barrel and were chambered for the .40 S&W cartridge as this was the most popular U.S. law enforcement round and would enable the Pitbull to be used as a back-up gun to the .40 service pistol. In October 2010 MKS discontinued the sales and marketing of Charter Arms. Charter now has taken over the sales and marketing function. At SHOT Show 2018, Charter introduced

3362-417: The action to remove the errant round, as cycling the action normally depends on the energy of a cartridge firing. With a revolver, this is not necessary as none of the energy for cycling the revolver comes from the firing of the cartridge, but is instead supplied by the user either through cocking the hammer or, in a double-action design, by just squeezing the trigger. Another significant advantage of revolvers

Charter Arms - Misplaced Pages Continue

3444-574: The barrel pivoted upwards, hinged on the forward end of the topstrap. On the S&;W tip-up revolvers, the barrel release catch is located on both sides of the frame in front of the trigger. Smith & Wesson discontinued it in the third series of the Smith & Wesson Model 1 1/2 but it was fairly widely used in Europe in the 19th century after a patent by Spirlet in 1870, which also included an ejector star. The most modern method of loading and unloading

3526-421: The barrel. Pulling the lever would drive a rammer into the chamber, pushing the ball securely in place. Finally, the user would place percussion caps on the nipples on the rear face of the cylinder. After each shot, a user was advised to raise the revolver vertically while cocking back the hammer so as to allow the fragments of the spent percussion cap to fall out safely. Otherwise, the fragments could fall into

3608-413: The best features of earlier designs. Top-break actions had the ability to eject all empty shells simultaneously and exposed all chambers for easy reloading, but having the frame hinged into two halves weakened the gun and negatively affected accuracy due to the lack of rigidity. "Side-loaders", like the earlier Colt Model 1871 and 1873, had a rigid frame, but required the user to eject and load one chamber at

3690-440: The bullet fires from the bottom chamber of the cylinder instead of the top chamber, as is typical in revolvers. This is intended to reduce muzzle flip , allowing for faster and more accurate repeat shots. In addition, the cylinder cross-section is hexagonal instead of circular, further reducing the weapon's profile. The first revolvers were front loading (also referred to as muzzleloading ), and were similar to muskets in that

3772-419: The costs associated with nuisance lawsuits for their financial trouble. After the company emerged from the bankruptcy, it was once again renamed to "Charter Arms", which it is still known as today. In September 2005, MKS Supply entered into an agreement with Charter Arms where MKS Supply would handle the sales, marketing and distribution for Charter Arms. In 2008, Charter Arms brought the new Patriot revolvers to

3854-485: The cylinder in place, with the chamber aligned with the barrel. When the trigger is pulled, it releases the hammer, which fires the round in the chamber. To fire again, the hammer must be manually cocked again. This is called "single-action" because the trigger only performs a single action, of releasing the hammer. Because only a single action is performed and trigger pull is lightened, firing a revolver in this way allows most shooters to achieve greater accuracy. Additionally,

3936-460: The cylinder when loading, so as not to damage the crane. One unique design was designed by Merwin Hulbert in which the barrel and cylinder assembly were rotated 90° and pulled forward to eject shells from the cylinder. In a single-action revolver, the hammer is manually cocked, usually with the thumb of the firing or supporting hand. This action advances the cylinder to the next round and locks

4018-593: The cylinder. The barrel and cylinder are then rotated back and locked in place, and the revolver is ready to fire. Top-break revolvers are able to be loaded more rapidly than fixed frame revolvers, especially with the aid of a speedloader or moon clip. However, this design is much weaker and cannot handle high pressure rounds. While this design has become mostly obsolete, supplanted by the stronger yet equally convenient swing-out cylinder design, manufacturers still make reproductions of late 19th century designs for use in cowboy action shooting . The first top-break revolver

4100-582: The earliest examples of the modern revolver were made in Germany. These weapons featured a single barrel with a revolving cylinder holding the powder and ball. They would soon be made by many European gun-makers, in numerous designs and configurations. However, these weapons were complicated, difficult to use and prohibitively expensive to make, and thus not widely distributed. In the early 19th century, multiple-barrel handguns called " pepper-boxes " were popular. Originally they were muzzleloaders , but in 1837,

4182-428: The firing mechanism and barrel. In contrast, other repeating firearms, such as bolt-action , lever-action , pump-action , and semi-automatic , have a single firing chamber and a mechanism to load and extract cartridges into it. A single-action revolver requires the hammer to be pulled back by hand before each shot, which also revolves the cylinder. This leaves the trigger with one "single action" to perform—releasing

4264-735: The first revolver to use self-contained metallic cartridges rather than loose powder, pistol ball , and percussion caps. It is a single-action , pinfire revolver holding six rounds. On November 17, 1856, Horace Smith and Daniel B. Wesson signed an agreement for the exclusive use of the Rollin White Patent at a rate of 25 cents for every revolver. Smith & Wesson began production late in 1857, and enjoyed years of exclusive production of rear-loading cartridge revolvers in America due to their association with Rollin White, who held

4346-498: The front and rear of the frame, and the frame is typically full thickness all the way around, fixed cylinder revolvers are inherently strong designs. Accordingly, many modern large caliber hunting revolvers tend to be based on the fixed cylinder design. Fixed cylinder revolvers can fire the strongest and most powerful cartridges, but at the price of being the slowest to load or unload since they cannot use speedloaders or moon clips to load multiple cartridges at once, as only one chamber

4428-432: The front of the cylinder rather than having to be loaded down the whole length of the barrel. Importantly, this allowed the barrel itself to be rifled , since the user was not required to force the tight-fitting bullet down the barrel in order to load it (a traditional muzzle-loading pistol had a smoothbore barrel and the shot was relatively loose-fitting, which allowed easy loading, but was much less accurate). After firing

4510-405: The gun is fired, the hammer does not actually strike the firing pin. Under normal firing circumstances a small steel bar (called a transfer bar ) is raised as the trigger is pulled, placing it into a position between the firing pin and the hammer itself. The falling hammer strikes the transfer bar, which in turn strikes the firing pin, discharging the weapon. If the trigger is not being pulled when

4592-487: The hammer falls, the transfer bar will not be in position and the weapon will not discharge. The Bulldog is apparently intended for light, fast bullets , as with heavier and slower bullets it is less accurate. With most ammunition types the muzzle velocity tends to be between 705 and 1000 feet per second (215 and 305 meters per second, respectively). For self-defense the Blazer 200-grain (13 g) Gold Dot is, apparently,

4674-595: The hammer to fire the shot. In contrast, with a self-cocking, or double-action, revolver, one long squeeze of the trigger pulls back the hammer and revolves the cylinder, then finally fires the shot, thus requiring more force and distance to pull the trigger than in a single-action revolver. They can generally be fired faster than a single-action, but with reduced accuracy in the hands of most shooters. Most modern revolvers are "traditional double-action", which means they may operate either in single-action or self-cocking mode. The accepted meaning of "double-action" has come to be

4756-499: The late 19th century. In Europe, however, arms makers were quick to adopt the double-action trigger. While the U.S. was producing weapons like the Model 1873, European manufacturers were building double-action models like the French MAS Modèle 1873 and the later British Enfield Mk I and II revolvers . (Britain relied on cartridge conversions of the earlier Beaumont–Adams double-action prior to this.) Colt's first attempt at

4838-630: The load of choice for the Bulldog. If the Bulldog is used to hunt, the most effective ammo is, reportedly, the 240- or 250-grain (16 g) SWC. With this bullet type, the shot is very powerful and has a strong penetration, but the recoil can easily be handled. Other ammo types are weaker or provide too much recoil. Five models of the Bulldog have been produced, allowing customers to choose between: .44 Special and .357 Magnum cartridges , gun lengths of 7.2 inches (184 mm) and 6.7 inches (171 mm) and barrel lengths of either 2.5 inches (64 mm) or 2.2 inches (56 mm). All Bulldog models have

4920-432: The long period of development of the revolver, many calibers have been used. Some of these have proved more durable during periods of standardization and some have entered general public awareness. Among these are the .22 Long Rifle , a caliber popular for target shooting and teaching novice shooters; .38 Special and .357 Magnum, known for police use; the .44 Magnum , famous from Clint Eastwood 's Dirty Harry films; and

5002-421: The majority of weapons using a revolver mechanism are handguns, other firearms may also have a revolver action . These include some models of rifles , shotguns , grenade launchers , and autocannons . Revolver weapons differ from Gatling-style rotary weapons in that in a revolver only the chambers rotate, while in a rotary weapon there are multiple full firearm actions with their own barrels which rotate around

5084-483: The market. The Patriot revolvers were chambered for the .327 Federal Magnum, and were available in 2.2" or 4" stainless steel models. The Charter Arms web site as of August 2011 no longer lists this model under the products category. Also in 2008, Charter Arms announced a new revolver: the Charter Arms Rimless Revolver. The new revolver would be able to load and fire rimless cartridges such as

5166-538: The most common, European arms makers were making numerous revolvers by that time as well, many of which found their way into the hands of the American forces. These included the single-action Lefaucheux and LeMat revolvers , as well as the Beaumont–Adams and Tranter revolvers—early double-action weapons in spite of being muzzle-loaders. In 1854, Eugene Lefaucheux introduced the Lefaucheux Model 1854 ,

5248-436: The next half century. Early revolvers were caplock muzzleloaders: the user had to pour black powder into each chamber, ram down a bullet on top of it, then place a percussion cap on the nipple at the rear of each chamber, where the hammer would fall on it and ignite the powder charge. This was similar to loading a traditional single-shot muzzle-loading pistol, except that the powder and shot could be loaded directly into

5330-405: The original Colt designs (and on nearly all single-action revolvers since, such as the famous Colt Single Action Army) is on the right side, which was done to facilitate loading while on horseback; with the revolver held in the left hand with the reins of the horse, the cartridges can be ejected and loaded with the right hand. Because the cylinders in these types of revolvers are firmly attached at

5412-505: The patent and vigorously defended it against any perceived infringement by other manufacturers (much as Colt had done with his original patent on the revolver). Although White held the patent, other manufacturers were able to sell firearms using the design, provided they were willing to pay royalties. After White's patent expired in April 1869, a third extension was refused. Other gun-makers were then allowed to produce their own weapons using

5494-425: The powder and bullet were loaded separately. These were caplocks or "cap and ball" revolvers, because the caplock method of priming was the first to be compact enough to make a practical revolver feasible. When loading, each chamber in the cylinder was rotated out of line with the barrel, and charged from the front with loose powder and an oversized bullet. Next, the chamber was aligned using the ramming lever underneath

5576-419: The rear-loading method, without having to pay a royalty on each gun sold. Early guns were often conversions of earlier cap-and-ball revolvers, modified to accept metallic cartridges loaded from the rear, but later models, such as the Colt Model 1872 "open top" and the Smith & Wesson Model 3 , were designed from the start as cartridge revolvers. In 1873, Colt introduced the famous Model 1873, also known as

5658-432: The revolver's hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot firearms that had to be reloaded after each shot. The hammer cocking in nearly all revolvers

5740-435: The revolver's mechanism and jam it. Caplock revolvers were vulnerable to "chain fires", wherein hot gas from a shot ignited the powder in the other chambers. This could be prevented by sealing the chambers with cotton, wax, or grease. Chain fire led to the shots hitting the shooters hand, which is one of the main reasons why revolver rifles were uncommon. By the time metallic cartridges became common, more effective mechanisms for

5822-478: The same as "self-cocking", so modern revolvers that cannot be pre-cocked are called "double-action-only". These are intended for concealed carry, because the hammer of a traditional design is prone to snagging on clothes when drawn. Most revolvers do not come with accessory rails , which are used for mounting lights and lasers , except for the Smith & Wesson M&P R8 ( .357 Magnum ), Smith & Wesson Model 325 Thunder Ranch ( .45 ACP ), and all versions of

5904-498: The same since 1873. Although originally made for the United States Army , the Model 1873 was widely distributed and popular with civilians, ranchers , lawmen , and outlaws alike. Its design has influenced countless other revolvers. Colt has discontinued its production twice, but resumed production due to popular demand. In the U.S., the single-action revolver remained more popular than the double-action revolver until

5986-407: The size of the gun and caliber of the bullet. Each chamber has to be reloaded manually, which makes reloading a revolver a much slower procedure than reloading a semi-automatic pistol. Compared to autoloading handguns, a revolver is often much simpler to operate and may have greater reliability. For example, should a semiautomatic pistol fail to fire, clearing the chamber requires manually cycling

6068-592: The specialized role as a shield gun; law enforcement personnel using a "bulletproof" gun shield sometimes opt for a revolver instead of a self-loading pistol, because the slide of a pistol may strike the front of the shield when fired. Revolvers do not suffer from this disadvantage. A second revolver may be secured behind the shield to provide a quick means of continuity of fire. Many police also still use revolvers as their duty weapon due to their relative mechanical simplicity and ease of use. In 2010, major revolver manufacturers started producing polymer frame revolvers like

6150-409: The travel is designed to not completely extract longer, unfired rounds). The cylinder may then be loaded (individually or with the use of a speedloader), closed, and latched in place. The pivoting part that supports the cylinder is called the crane; it is the weak point of swing-out cylinder designs. Using the method often portrayed in movies and television of flipping the cylinder open and closed with

6232-446: Was later moved to Stratford, Connecticut , and a few years later, in 1978, Doug McClennahan retired from Charter Arms. David Ecker became the company's sole owner and brought his son, Nick, as part-owner to replace McClenahan. In 1988, the company was purchased by Jeff Williams, who renamed it to "CHARCO" and moved production to Ansonia, Connecticut . In 1996, the company filed for bankruptcy and two years later, closed its doors. However,

6314-409: Was made with the ability to chamber 25 different cartridges with bullet diameters between .355" and .357". Revolver technology is also present in other weapons used by the U.S. military. Some autocannons and grenade launchers use mechanisms similar to revolvers, and some riot shotguns use spring-loaded cylinders holding up to 12 rounds. In addition to serving as backup guns, revolvers still fill

6396-421: Was patented in France and Britain at the end of December in 1858 by Devisme. The most commonly found top-break revolvers were manufactured by Smith & Wesson, Webley & Scott, Iver Johnson, Harrington & Richardson, Manhattan Fire Arms, Meriden Arms , and Forehand & Wadsworth . The tip-up revolver was the first design to be used with metallic cartridges in the Smith & Wesson Model 1 , on which

6478-502: Was released. Designed by the founder of the first version of Charter Arms, Doug McClenahan, the Bulldog was released in 1973. It was one of the best-selling weapons of the 1970s and the 1980s in the United States. Its design and execution, which were quite modern at the time, caught the attention of the gun press and combat shooters. By the mid-1980s, more than half a million units had been produced and nearly 37,000 were being manufactured every year. Bulldog production has been stopped

6560-440: Was then reissued as U.S. patent RE00124 entitled Revolving gun on October 24, 1848. This was followed by U.S. patent 0,007,613 on September 3, 1850, for a Revolver , and by U.S. patent 0,007,629 on September 10, 1850, for a Revolver . In 1855, Rollin White patented the bored-through cylinder entitled Improvement in revolving fire-arms U.S. patent 00,093,653 . In 1856, Horace Smith & Daniel Wesson formed

6642-481: Was to avoid using the side plate designs manufactured by other revolver makers for a one-piece frame, giving the new revolver a strength that allowed it to safely shoot high loads. McClenahan also reduced the number of moving parts used in the gun and created a transfer bar safety device for the firing pin that would later be copied by manufacturers such as Ruger and Colt. In 1967, McClenahan's lifelong friend, David Ecker, became part-owner of Charter Arms. Production

6724-542: Was used in his guns to rotate the cylinder by cocking the hammer. This provided a reliable and repeatable way to index each round and did away with the need to manually rotate the cylinder. Revolvers proliferated largely due to Colt's ability as a salesman , but his influence spread in other ways as well. The build quality of his company 's guns became famous, and its armories in America and England trained several seminal generations of toolmakers and other machinists , who had great influence in other manufacturing efforts of
