Glock 47
Glock (; stylized as GLOCK) is a brand of polymer- framed, short-recoil-operated, striker-fired, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock Ges.m.b.H. The firearm entered Austrian military and police service in 1982 after becoming the top performer in reliability and safety tests. Glock pistols have become the company's most profitable line of products, and have been supplied to national armed forces, security agencies, and police forces in at least 48 countries. Glocks are also popular among civilians for recreational shooting, competition shooting, and self-defense. History The company's founder and head engineer, Gaston Glock (1929–2023), had no experience with firearms design or manufacture at the time his first pistol, the Glock17, was being prototyped. Glock had extensive experience in advanced synthetic polymers, which was instrumental in the company's design of the first commercially successful line of pistols wit ...

Norwegian Armed Forces
The Norwegian Armed Forces () are the armed forces responsible for the defence of Norway. It consists of five branches, the Norwegian Army, the Royal Norwegian Navy, which includes the Norwegian Coast Guard, Coast Guard, the Royal Norwegian Air Force, the Home Guard (Norway), Home Guard, and Norwegian Cyber Defence Force as well as several joint departments. The military force in peacetime is around 17,185 personnel including military and civilian staff, and around 70,000 in total with the current military personnel, conscripts and the Norwegian Home Guard in full mobilization. Among European NATO members, the military expenditure of US$7.2 billion is the highest per capita. History An organised military was first assembled in Norway in the 9th century and its early focus was naval warfare. The army was created in 1628 as part of Denmark–Norway, followed by two centuries of regular wars. A Norwegian military was established Norway in 1814, in 1814, but the military did not s ...

10mm Auto
The 10mm Auto (also known as the 10×25mm, official C.I.P. nomenclature: 10 mm Auto, official SAAMI nomenclature: 10mm Automatic) is a powerful and versatile semi-automatic pistol cartridge introduced in 1983. Its design was adopted and later produced by ammunition manufacturer FFV Norma AB of Åmotfors, Sweden. The 10mm was selected for service by the Federal Bureau of Investigation (FBI) in 1989 in the aftermath of the 1986 FBI Miami shootout. During the testing and development process, the FBI Firearms Training Unit developed a downloaded version of the 10mm cartridge which they felt provided adequate performance while minimizing recoil and muzzle blast. It is commonly claimed that this reduced loading was developed as the result of complaints or training problems involving agents who were issued the 10mm, but the reduced loading was developed before any pistols were issued. The cartridge was later decommissioned (except for use by the Hostage Rescue Team and S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Striker-fired
A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer. The terms may also be used for a component of equipment or a device which has a similar function. Such equipment or devices include: artillery, munitions and pyrotechnics. Firearms The typical firing pin is a thin, simple rod with a hardened, rounded tip that strikes and crushes the primer. The rounded end ensures the primer is indented rather than pierced (to contain propellant gasses). It sits within a hole through the breechblock and is struck by the hammer when the trigger is "pulled". A light firing-pin spring is often used to keep the firing pin rearward. It may be termed a ''firing-pin return spring'', since it returns it t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receiver (firearms)
In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing (engineering), housing for internal action (firearms), action components such as the hammer (firearms), hammer, bolt (firearms), bolt or breechblock, firing pin and extractor (firearms), extractor, and has screw thread, threaded interfaces for externally attaching ("receiving") components such as the gun barrel, barrel, stock (firearms), stock, trigger (firearms), trigger mechanism and iron sights, iron/sight (device)#Optical sights, optical sights. Some firearm designs, such as the AR-15 platform, feature receivers that have 2 separate sub-assemblies called the upper receiver which houses the barrel/trunnion, bolt components etc and the lower receiver (Trigger Mechanism Housing in some cases) that holds the fire control group, pistol grip, selector, stock etc. The receiver is often made of forged, machined, or stamped steel or aluminium.

Polymer
A polymer () is a chemical substance, substance or material that consists of very large molecules, or macromolecules, that are constituted by many repeat unit, repeating subunits derived from one or more species of monomers. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form Amorphous solid, amorphous and crystallization of polymers, semicrystalline structures rath ...

Drum Magazine
A drum magazine is a type of high-capacity magazine for firearms. Cylindrical in shape (similar to a drum), drum magazines store rounds in a spiral around the center of the magazine, facing the direction of the barrel. Drum magazines are contrasted with more common box-type magazines, which have a lower capacity and store rounds flat. The capacity of drum magazines varies, but is generally between 50 and 100 rounds. History and usage 1800s In 1853, the first revolving drum magazine was patented by Charles N. Tyler, and the first modern one by William H. Elliot, better known as the inventor of the Remington Model 95, Remington Double Derringer, in 1871. 1900s Pistols and rifles A drum magazine was built for the Luger pistol, Luger (Pistole 1908) pistol; although the Luger usually used an 8-cartridge box magazine, the optional 32-cartridge ''Schneckenmagazine'' ("snail magazine") was also sometimes used. Moubray G. Farquhar and Arthur H. Hill applied for a British patent for " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Detachable Box Magazine
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridge (firearms), cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the gun barrel, barrel chamber (firearms), chamber by the firearm's moving action (firearms), action. The detachable magazine is sometimes colloquially referred to as a "clip (ammunition), clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder. Magazines come in many shapes and sizes, from integral tubular magazines on lever-action and pump-action rifles and shotguns, that may hold more than five rounds, to detachable box magazines and drum magazines for automatic rifles and light machine guns, that may h ...

Blowback (arms)
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil ope ...

Recoil Operation
Recoil operation is an operating mechanism used to implement locked-breech autoloading firearms. Recoil operated firearms use the energy of recoil to cycle the action, as opposed to gas operation or blowback operation using the pressure of the propellant gas. History The earliest mention of recoil used to assist the loading of firearms is sometimes claimed to be in 1663 when an Englishman called Palmer proposed to employ either it or gases tapped along a barrel to do so. However no one has been able to verify this claim in recent times, although there is another automatic gun that dates from the same year, but its type and method of operation are unknown. Recoil-operation, if it was invented in 1663, would then lie dormant until the 19th century, when a number of inventors started to patent designs featuring recoil operation; this was due to the fact that the integrated disposable cartridge (both bullet and propellant in one easily interchangeable unit) made these designs vi ...

45 GAP
The .45 GAP (Glock Auto Pistol) or .45 Glock (11.43×19mmRB) is a pistol cartridge designed by Ernest Durham, an engineer with CCI/Speer, at the request of firearms manufacturer Glock to provide a cartridge that would equal the power of the .45 ACP, have a stronger case head to reduce the possibility of case neck blowouts, and be shorter to fit in a more compact handgun. The .45 GAP is the first commercially introduced cartridge that has been identified with Glock. Development The .45 GAP has the same diameter as the .45 ACP pistol cartridge but is slightly shorter, and uses a small-pistol primer instead of the large-pistol primer most commonly used in .45 ACP ammunition. Originally, the maximum bullet weight of the .45 GAP was . In order to provide terminal ballistics that matched the standard .45 ACP loads, the .45 GAP was designed to operate at a higher standard pressure—roughly equivalent to the higher pressures found in .45 ACP "+P" rounds. Since the .45 GAP has a mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
45 ACP
The .45 ACP (Automatic Colt Pistol), also known as .45 Auto, .45 Automatic, or 11.43×23mm is a Rim (firearms)#Rimless, rimless straight-walled handgun Cartridge (firearms), cartridge designed by John Moses Browning in 1904, for use in his prototype Colt's Manufacturing Company, Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun cartridge. The standard-issue military .45 ACP cartridge uses a round-nose bullet at approximately fired from a government-issue M1911A1 pistol. It operates at a relatively low maximum chamber pressure rating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
40 S&W
The .40 S&W (10.2×22mm) is a Rim (firearms), rimless pistol Cartridge (firearms), cartridge developed jointly by American firearms manufacturers Smith & Wesson and U.S. Repeating Arms Company, Winchester in 1990. The .40 S&W was developed as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9 mm size) semi-automatic handguns. It uses bullets ranging in weight from .''Hornady Handbook of Cartridge Reloading'', Fourth Edition (1991), pp. 593–595 History In the aftermath of the 1986 FBI Miami shootout, in which two FBI special agents were killed and five wounded, the FBI started the process of testing 9×19mm Parabellum and .45 ACP ammunition in preparation to replace its standard-issue revolver with a semi-automatic pistol. The semi-automatic pistol offered two advantages over the revolver: increased ammunition capacity and increased e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
