Arsenal Firearms Strike One
The Arsenal Firearms "Strike One" is a polymer or Ergal- framed, short recoil operated, striker-fired semi-automatic pistol introduced by the company Arsenal Firearms in 2012. The Strike One is known in Russia as the «Стриж» ("Strizh", Swift bird). Development The AF-1 Strike One uses a Bergmann System introduced in the Bergmann–Bayard pistol. Unlike the Browning system, the barrel does not tilt. It is locked with a Y shaped part that during the recoil locks the barrel and bolt and halfway through it drops, releasing the barrel. The barrel stops its motion, the bolt continues back, ejecting the spent cartridge case and loading fresh cartridge and on its way back the Y shaped locking fork reengages and the barrel and bolt move together forward. Instead of tilting the barrel only moves in a straight line, thus increasing the accuracy. The Strike one is rated for +P+ ammunition and specifically set up to fire Russian 9×19mm ammunition 7N21 and 7N31 which are close to .357 ...

Semi-automatic Pistol
A semi-automatic pistol is a type of repeating single-chamber handgun ( pistol) that automatically cycles its action to insert the subsequent cartridge into the chamber (self-loading), but requires manual actuation of the trigger to actually discharge the following shot. As a result, only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/ striker until the trigger has been released and reset. Additional terms sometimes used as synonyms for a semi-automatic pistol are self-loading pistol, autopistol, autoloading pistol, and automatic pistol (E.G.: Automatic Colt Pistol). A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt, which is usually housed inside the slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer/s ...

Bore Axis
The bore axis of a firearm is the longitudinal axis through the geometric center of the gun barrel. In a rifled barrel, the projectile (bullet/ball, pellet or slug) will spin around the bore axis as it goes through the barrel. Boresighting is a process of placing one's line of sight down along the bore axis. Bore-to-sight distance The distance between the bore axis and the sight axis (the optical axis of a sighting device), also known as the ''sight height'', is an important factor to consider due to parallax principles. It is normally desirable to keep the sights of a firearm as close to the bore as possible, since a firearm with a large bore-to-sight distance will require more compensatory sight adjustment when shifting between shooting at different targets at close ranges (due to foreshortening). On the other hand, a firearm with a short bore-to-sight distance will need less sight adjustment when changing between targets at close ranges. At longer ranges the bore-to-s ...

22 LR
The .22 Long Rifle or simply .22 LR or 22 (metric designation: 5.6×15mmR) is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of rifles, pistols, revolvers, smoothbore shotguns, and submachine guns. In terms of units sold it is by far the most common ammunition in the world today. Common uses include hunting and shooting sports. Ammunition produced in .22 Long Rifle is effective at short ranges, has little recoil, and is cheap to purchase, making it ideal for training. History American firearms manufacturer J. Stevens Arms & Tool Company introduced the .22 Long Rifle cartridge in 1887. The round owes its origin to the .22 BB Cap of 1845 and the .22 Short of 1857. It combined the case of the .22 Long of 1871 with a bullet, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, rendering the .22 Extra Long cartridges obsolete. The .22 LR ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PRIME Ammunition
A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, or , involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order. The property of being prime is called primality. A simple but slow method of checking the primality of a given number n, called trial division, tests whether n is a multiple of any integer between 2 and \sqrt. Faster algorithms include the Miller–Rabin primality test, which is fast but has a small chance of error, and the AKS primality test, which al ...

SHOT Show
The SHOT Show , which is an acronym for "Shooting, Hunting and Outdoor Trade Show", is an American annual trade show for the shooting sports, hunting, outdoor recreations and firearm manufacturing industries. The show is owned and sponsored by the National Shooting Sports Foundation (NSSF), and is the biggest event of the type in the world along with the IWA & OutdoorClassics ("IWA Nuremberg") held also annually in Nuremberg, Germany. The SHOT Show is restricted to formal members of the shooting, hunting, military and outdoor trade industries, including commercial buyers and sellers of military, law enforcement and tactical products, and is not open to the general public. The first ever SHOT Show was held in St. Louis, Missouri, in 1979. It used to rotate between Las Vegas, Nevada; Orlando, Florida; New Orleans, Louisiana, and several other U.S. cities, although since 2010 it has taken place only in Las Vegas at the Sands Expo The Venetian Convention and Expo Center (formerl ...

Beretta 92
The Beretta 92 (also Beretta 96 and Beretta 98) is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. The Beretta 92 was designed in 1975, and production began in 1976. Many variants in several different calibers continue to be used to the present. The United States military replaced the .45 ACP M1911A1 pistol in 1985 with the Beretta 92FS, designated as the " M9." History The Beretta 92 pistol evolved from earlier Beretta designs, most notably the M1923 and M1951. From the M1923 comes the open slide design, while the alloy frame and locking block barrel, originally from Walther P38, were first used in the M1951. The grip angle and the front sight integrated with the slide were also common to earlier Beretta pistols. What were perhaps the Model 92's two most important advanced design features had first appeared on its immediate predecessor, the 1974 .380 caliber Model 84. These improvements both involved the magazine, which featured direct feed; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locked-breech
Locked breech is the design of a breech-reloading firearm's action. This 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 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 the pressure drop, a breech block can be opened in a self-reloading fire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heckler & Koch USP
The USP (''Universelle Selbstladepistole'' or "universal self-loading pistol") is a semi-automatic pistol developed in Germany by Heckler & Koch GmbH (H&K) as a replacement for the P7 series of handguns. History Design work on a new family of pistols commenced in September 1989, focused primarily on the United States commercial and law enforcement markets. USP prototypes participated in rigorous testing alongside H&K's entry in the Offensive Handgun Weapon System (OHWS) program requested by the U.S. Special Operations Command (USSOCOM), which would later result in the Mk 23 Mod 0. The USP prototypes were then refined in 1992, based on input from the OHWS trials, and the design was finalized in December of the same year. The USP was formally introduced in January 1993 with the USP40 model (the base version) chambered for the increasingly popular .40 S&W cartridge, followed soon by the USP9 (using the 9×19mm Parabellum cartridge), and in May 1995—the USP45 (caliber .45 ACP).
