26-513: The Model C-9 is a compact, single-stack magazine, model of Hi-Point 's 9×19mm handgun. It consists of a polymer frame, zinc-alloy slide and bolt (with steel reinforcing inserts), and a steel breech, chamber and barrel. Its low price and small and compact design prompted many to purchase it for concealed carry . Hi-Point's handguns use a blowback design similar to that used in the Walther PPK and Russian Makarov PM . In blowback weapons

52-730: A different type of locking system. This one is the Beretta Rotary locking system found in their PX Four Storm handgun. The next photograph on the left is of the CZ model 52 showing a roller locking system. Some sources describe this as a delayed blowback action but it is actually a locked breech. In the late 19th century, firearms makers learned how to use this mechanical force to create "self-loading" weapons, whether they were in artillery, rifles, shotguns, or handguns. The lower-powered calibers such as .22 caliber rimfire , (example gun) Walther P22 .22 Rimfire handgun were able to self-load using

78-422: A high-pressure pocket of gas that expands, pushing the projectile (bullet) out of the chamber and down the barrel of the firearm. If the high-pressure gas were not confined within certain parts of the weapon, it could damage the firearm or injure the shooter. A 'locked breech' barrel confines the high-pressure gas to the barrel, allowing the gas to expand and cool without risk of damaging weapon or shooter. Because of

104-473: A locked-breech design and therefore do not require the amount of slide mass that the blowback design requires in order to remain comfortable to shoot, safe to fire, and easy to control during the firing process. The C-9 Comp. (short for "Compensated") is the larger version of Hi-Point's 9 mm handgun. Its major difference from the C-9 Compact is that it has a specially designed "compensator" attached to

130-409: A locked-breech gun firing the same caliber. The Hi-Point carbine is a series of pistol-caliber carbines manufactured by Hi-Point Firearms chambered for 9×19mm Parabellum , .40 S&W , 10mm Auto , .45 ACP and .380 ACP . They are very inexpensive, constructed using polymers and alloyed metals as much as possible, resulting in a reduction of production costs and sale price. It functions via

156-453: A new safety, new grip texturing, " Glock -style" front sights, and an elongated sight base, allowing for a Picatinny rail . Limited numbers of C-9s with YEET Cannon G1 marked on the slide became available starting on July 17, 2019. YC9s were planned to become available for sale in 2020, and became available summer of 2023 The C-9, C-9 Compensated, and other Hi-Point handguns have been criticized for their weight. In response to this complaint,

182-402: A simple direct blowback action . Hi-Point carbines use a polymer stock, stamped sheet metal receiver cover, and a receiver and bolt cast from Zamak-3. The barrel is steel and button rifled using a 1-10" right hand twist. Hi-Point manufactures firearms in the following calibers: Hi-Point firearms have a manual thumb safety and an integral drop safety that prevents firing in the event that

208-484: A small punch or a screwdriver and a hammer to remove a pin in the receiver, in order to permit slide removal (and thus enable field-stripping). Rather than being machined from forged steel, the slide is die cast from Zamak-3 . Zamak is a zinc alloy which is often used in low cost firearms; previous manufacturers using this technique included Lorcin Engineering Company and Raven Arms . Die casting

234-475: A tilting barrel which allowed loading without having to pull the slide to the rear. Gun makers developed ways to keep the actions from opening too soon by "locking" the breech closed. Using this technique a firearm, such as the Colt .45 ACP Government model handgun was made which featured a grooved barrel and a grooved slide which were cammed together to prevent the breech from opening. The camming mechanism "locked"

260-449: Is 6 oz (170 g) heavier than the new model, and 2 oz (57 g) heavier than the older model of the C-9 Compact. The YC9, an improved version of the C-9, was developed in 2019. The pistol's name was decided after an online contest, in which Yeet Cannon received 313,000 votes, over 96% of the total. The weapon's length, weight, and caliber are identical to the C-9, but it features

286-621: Is an American firearms manufacturer based in Mansfield , Ohio . All of their firearms are manufactured in several different locations in Ohio. Hi-Point semi-automatic pistols are polymer framed handguns based on the blowback design. Different from other blowback design pistols such as the Walther PPK , the P-64 , and the Astra 600 which use a heavy slide combined with a stiff recoil spring to hold

312-485: Is described by Newton's third law of motion , which states that for every action there is an equal and opposite reaction. This force is felt in the hand or on the shoulder when a person fires a handgun or a rifle. It takes the form of a quick sharp push away from the path the bullet is flying in and directly against the hand or shoulder of the shooter. The locked breech systems in handguns and rifle vary significantly. The photograph showing four handgun barrels illustrates

338-426: Is important in understanding how a self-reloading firearm works. In the simplest terms, the locked breech is one way to slow down the opening of the breech of a self-reloading firearm when fired. The source of power for the movement is recoil . The principle of firing a projectile from a firearm is that when the propellant in a bullet's casing is ignited, the propellant burns quickly for a very short time. This creates

364-473: Is particularly commonplace in Ohio, which influenced the decision to implement it. Uncommon for this construction, Hi-Point pistols are rated for +P ammunition in calibers up to .45 ACP. Blowback designs are generally simpler in design and easier and cheaper to manufacture than locked-breech recoil-operated firearms. While the fixed barrel of a blowback gun generally will contribute to improved accuracy, blowback guns usually need to be larger and heavier than

390-608: The Browning M2HB .50 caliber machine gun a similar system called long recoil is used. The difference is how far the breech and barrel recoil together after a shot is fired. Locked recoil systems rely on timing to allow safe operation. A very heavy bolt mechanism can be used (such as in sub-machineguns) to slow the rate of movement and reduce the rate of fire. This is not adequate with higher velocity and higher energy cartridges. Rifles and most handguns use locked breech designs to control recoil safely. The amount of mass of

416-423: The addition of accessories such as a flashlight or laser sights for better target identification. Another difference between the C-9 and C-9 Comp. is the barrel length. Its 4 in (102 mm) barrel is 1 ⁄ 2  in (12.7 mm) longer than its sister weapon's providing for better accuracy and balance. The compensator and extra bulk also increase the weight. Weighing in at 35 oz (992 g), it

442-442: The breech closed until the entire barrel and slide assembly had moved far enough that the pressure in the chamber was low enough to safely unlock the breech during the process of ejecting the spent casing which was followed by loading a new loaded cartridge. Firearms that are physically small, such as handguns, use a system of recoil referred to as short recoil . This is adequate for the smaller calibers. In large firearms such as

468-501: The breech closed, these pistols use a heavier slide so they can use a softer recoil spring. When compared to breech-locking handguns of the same caliber and dimensions, the Hi-Point is rather top heavy. As with most blowback handguns, this pistol has fewer moving parts to clean and lubricate than its locked breech counterparts. While most semi-automatic pistols can be field stripped without the use of any tools, Hi-Point pistols require

494-415: The changes needed for a firearm to be able to control the higher amount of inertia and higher chamber pressures resulted in firearms design changes. Some designers handled this problem by making the moving parts of the firearm heavier and the strength of the recoil spring much greater. Firearms such as the .25 ACP Beretta SB950, take a great deal of force to chamber a round. Beretta solved this problem with

520-665: The empty or unloaded weight of the C-9 has been trimmed from 29 ounces (822 g) to 25 ounces (709 g) by using a polymer frame, making its weight comparable to other pistols with similar magazine capacities. Like other Hi-Point pistols, field stripping the C-9 requires the use of a small punch or a small screwdriver and a hammer to remove a spring pin in the receiver. The weapon's overall reliability has been questioned because of different kinds of jamming : misfeed and failure to return to battery among others. Hi-Point Firearms Hi-Point Firearms , also known as Strassell's Machine, Inc (distributed by MKS Supply ),

546-467: The end of the barrel. The compensator works as a muzzle brake, by forcing some of the hot gases escaping behind the bullet to go upward through specially drilled holes in the top of the compensator. The escaping gases push the end of the gun downward; helping to eliminate some of the upward motion caused by the natural recoil of the gun. The underside of the C-9 Comp. has been machined with rails to accept

572-446: The energy produced by the .22 rimfire cartridges which simply blew the action open to reload a new cartridge. (This is called simple blowback .) As cartridges grew in size and power the amount of recoil in the chamber increased. The energy created by larger and higher pressure cartridges, such as 9×19mm Parabellum pistol cartridge, results in violent movement of the gun's action. In the case of simple blowback (and delayed blowback)

598-573: The evolution of handgun locked breech systems in four of the most famous firearms. This is from the Browning Hi-Power (I in the photograph), John Browning's last design. The second barrel is of the same action type in the CZ 75 handgun. The third barrel type is from an HK USP pistol. The fourth barrel is from a Glock (which uses the SIG Sauer system). The photograph on the right is of

624-432: The firearm is dropped. Until the 2000s, all Hi-Point products except the 995 (9mm) carbine had a last-round lock open and magazine disconnect safety, preventing firing unless a magazine was in the gun. With the replacement of the original 9mm carbine with the new 995 TS model, all pistols and carbines now have these features. Locked breech Locked breech is the design of a breech-reloading firearm's action . This

650-478: The mass of the slide and bolt absorbs the rearward force generated by the propulsion of the bullet . As the pressure drops to a safe level, the slide moves back (along with the bolt), an extractor hooks the empty casing and pulls it out of the chamber, after which the case is ejected from the weapon by the ejector. When the slide has completed its rearward travel, the recoil spring moves the slide forward, chambering another round. Many, if not most, modern handguns use

676-518: The pressure drop, a breech block can be opened in a self-reloading firearm due to the recoil inertia generation by the movement of the projectile. The main difference is that there is a very strong lock in the locked breech action whereas blowback systems rely on the inertia of components to provide safe operation. The type of action used by a firearms designer will be determined by the design goal inherent for that firearm. The three actions described are increasingly more expensive to manufacture. Recoil
