M1911 Pistol
The M1911 (Colt 1911 or Colt Government) is a single-action, recoil-operated, semi-automatic pistol chambered for the .45 ACP cartridge. The pistol's formal U.S. military designation as of 1940 was ''Automatic Pistol, Caliber .45, M1911'' for the original model adopted in March 1911, and ''Automatic Pistol, Caliber .45, M1911A1'' for the improved M1911A1 model which entered service in 1926. The designation changed to ''Pistol, Caliber .45, Automatic, M1911A1'' in the Vietnam War era. Designed by John Browning, the M1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol was widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols. It is popular with civilian shooters in competitive events such as the International Defensive Pistol Association and International Practical Shooting Confederation. The U.S. military procured around 2.7 million M1911 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blind Spot (vehicle)
A blind spot in a vehicle or vehicle blind spot is an area around the vehicle that cannot be directly seen by the driver while at the controls, under existing circumstances. In transport, driver visibility is the maximum distance at which the driver of a vehicle can see and identify prominent objects around the vehicle. Visibility is primarily determined by weather conditions (see visibility) and by a vehicle's design. The parts of a vehicle that influence visibility include the windshield, the dashboard and the pillars. Good driver visibility is essential to safe road traffic. Conditions for blind spots Blind spots exist in a wide range of vehicles: aircraft, cars, buses, trucks, agricultural equipments, heavy equipments, boats, ships, trams, and trains. Blind spots may occur in the front of the driver when the A-pillar (also called the windshield pillar), side-view mirror, or interior rear-view mirror block a driver's view of the road. Behind the driver, cargo, headrest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shooting
Shooting is the act or process of discharging a projectile from a ranged weapon (such as a gun, bow, crossbow, slingshot, or blowpipe). Even the acts of launching flame, artillery, darts, harpoons, grenades, rockets, and guided missiles can be considered acts of shooting. When using a firearm, the act of shooting is often called firing as it involves initiating a combustion ( deflagration) of chemical propellants. Shooting can take place in a shooting range or in the field, in shooting sports, hunting, or in combat. The person involved in the shooting activity is called a shooter. A skilled, accurate shooter is a '' marksman'' or '' sharpshooter'', and a person's level of shooting proficiency is referred to as their ''marksmanship''. Competitive shooting Shooting has inspired competition, and in several countries rifle clubs started to form in the 19th century. Soon international shooting events evolved, including shooting at the Summer and Winter Olympics (f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9×19mm Parabellum
The 9×19mm Parabellum (also known as 9mm Parabellum or 9mm Luger or simply 9mm) is a rimless, tapered firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, it is widely considered the most popular handgun and submachine gun cartridge due to its low cost and extensive availability. It is a standard cartridge for NATO forces as well as in many non-NATO countries. Since the cartridge was designed for the Luger semi-automatic pistol, it has been given the designation of 9mm Luger by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the Commission internationale permanente pour l'épreuve des armes à feu portatives (CIP). A 2007 US survey concluded that "about 60 percent of the firearms in use by police are 9mm arabellum and credited 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.Adler, Jerry, et al.

CZ 75
The CZ 75 is a semi-automatic pistol made by Czech firearm manufacturer ČZUB. First introduced in 1975, it is one of the original " wonder nines" and features a staggered-column magazine, all-steel construction, and a hammer forged barrel. It is widely distributed throughout the world and is the most common handgun in the Czech Republic. History Development of CZ 75 The armament industry was an important part of the interwar Czechoslovak economy and made up a large part of the country's exports (see, for example, Bren light machine gun, which was a modified version of the Czechoslovak ZB vz. 26). However following the 1948 communist coup d'état, all heavy industry was nationalized and was (at least officially) cut off from its Western export market behind the Iron Curtain. While most other Warsaw Pact countries became dependent on armaments imports from the Soviet Union, most of the Czechoslovak weaponry remained domestic (for example, the Czechoslovak army used the Vz. ...

10mm Auto
The 10mm Auto (10×25mm, official C.I.P. nomenclature: 10 mm Auto, official SAAMI nomenclature: 10mm Automatic) is a semi-automatic pistol cartridge introduced in 1983. Its design was adopted and later produced by ammunition manufacturer FFV Norma AB of Åmotfors, Sweden. Although it was selected for service by the Federal Bureau of Investigation (FBI) in 1989, in the aftermath of the 1986 FBI Miami shootout, the cartridge was later decommissioned (except by the Hostage Rescue Team and Special Weapons and Tactics Teams) after their Firearms Training Unit eventually concluded that its recoil was excessive in terms of training for average agents and police officers' competency of use and qualification, and that the pistols chambered for the cartridge were too large for some small-handed individuals. These issues led to the creation of and following replacement by a shorter version of the 10mm that exists today as the .40 S&W, and while the 10mm never attained the mainstrea ...

Bren Ten
The Bren Ten is a semi-automatic pistol chambered for 10mm Auto that was made by Dornaus & Dixon Enterprises Inc. from 1983 to 1986. While the Bren Ten's design has an appearance similar to the 9×19mm Parabellum CZ-75, it is larger and stronger with several unique design elements that make it a distinctly separate firearm. The design was produced only in small numbers before the company went bankrupt. Subsequent attempts to bring the firearm back into production have been unsuccessful. The Bren Ten remains a weapon of some controversy. Many enthusiasts consider it to be one of the best pistols of its era, and the 10mm Auto is one of the most powerful semi-automatic pistol rounds. Issues reported with the gun when it was in its original production run included some of the units delivered with missing or inoperable magazines. Spare magazines were hard to find and were relatively expensive. The 10mm Auto caliber was at first unique to this pistol, and produced initially by FFV No ...

Negligent Discharge
An unintentional discharge is the event of a firearm discharging (firing) at a time not intended by the user. An unintended discharge may be produced by an incompatibility between firearm design and usage, such as the phenomenon of cooking off a round in a closed bolt machine gun, a mechanical malfunction as in the case of slamfire in an automatic weapon, or be user induced due to training issues or negligence. The phenomenon has also been defined in scientific literature as ''an activation of the trigger mechanism that results in an unplanned discharge that is outside of the firearm’s prescribed use''. Where prescribed use refers to departmental policies and laws related to the operation of firearms (O'Neill, 2018). Types Accidental discharge An accidental discharge (AD) occurs when there is a mechanical failure of the firearm. This can include things like firearms that do not have mechanisms to render them drop safe falling a sufficient distance, a firing pin stuck forward, ...

Weaver Stance
The Weaver stance is a shooting technique for handguns. It was developed by Los Angeles County Deputy Sheriff Jack Weaver during freestyle pistol competition in Southern California during the late 1950s. Description The Weaver stance has two main components. # The first component is a two-handed technique in which the shooting hand holds the handgun while the support hand wraps around the shooting hand. The shooting arm's elbow is slightly bent (almost locked out) while the support elbow is noticeably bent straight down. The shooter pushes forward with his/her shooting hand while the support hand exerts rearward pressure on the firearm. The resultant isometric tension from the support hand is intended to lessen and control muzzle flip when the firearm is fired, allowing for faster follow-up shots. # The second component is the positioning of the feet in a boxing stance, with the non-shooting side foot ahead of the shooting side foot. A person shooting right-handed will have the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistol
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict laws and regulations governing thei ...
