Close-up shot of a safety of an M16A2 rifle In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties can generally be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for example, toggling a lever from "on" to "off" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively. Firearms with the ability to allow the user to select various fire modes may have separate switches for safety and for mode selection (e.g. Thompson submachine gun) or may have the safety integrated with the mode selector as a fire selector with positions from safe to semi-automatic to full-automatic fire (e.g. M16). Some firearms manufactured after the late 1990s and early 2000s include a mandatory integral locking mech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Trigger (firearms)
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flattened lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single-action", meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walther PP
The Walther PP (german: Polizeipistole, or police pistol) series pistols are blowback-operated semi-automatic pistols, developed by the German arms manufacturer Carl Walther GmbH Sportwaffen. It features an exposed hammer, a traditional double-action trigger mechanism, a single-column magazine, and a fixed barrel that also acts as the guide rod for the recoil spring. The series includes the Walther PP, PPK, PPK/S, and PPK/E models. The Walther TPH pocket pistol is a smaller calibre pistol introduced in 1971 identical in handling and operation to the PPK. Various PP series are manufactured in Germany, France and the United States. In the past, the PPK version was manufactured by Walther in its own factory in Germany, as well as under licenses by Manurhin in France; Interarms in Virginia and by Smith & Wesson in Maine. Since 2018, PPK and PPK/S models have been built at the factory of US-based subsidiary Walther Arms, Inc. The PP and the PPK were among the world's first successful ...

Sear (firearm)
In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon. The sear may be a separate part or can be a surface incorporated into the trigger. Sear mechanisms are also frequently employed in archery release aids. Description As one firearms manufacturer notes: Sear: A sharp bar, resting in a notch (or in British: "bent") in a hammer (or in British: "tumbler"), holding the hammer back under the tension of the mainspring. When the trigger is pulled, the sear moves out of its notch, releasing the hammer and firing the gun. The term "sear" is sometimes incorrectly used to describe a complete trigger group. Within a trigger group, any number of sears may exist. For example, a Ruger Blackhawk single-action revolver contains one for releasing the hammer. A Ruger Redhawk double/single-ac ...

Browning Hi-Power
The Browning Hi-Power is a single-action, semi-automatic pistol available in the 9×19mm Parabellum and .40 S&W calibers. It was based on a design by American firearms inventor John Browning, and completed by Dieudonné Saive at FN Herstal. Browning died in 1926, several years before the design was finalized. FN Herstal initially named the design the "High Power", which alludes to the 13-round magazine capacity, almost twice that of other designs at the time, such as the Luger or Colt M1911. During World War II, Belgium was occupied by Nazi Germany and the FN factory was used by the Wehrmacht to build the pistols for their military, under the designation "9mm Pistole 640(b)". FN Herstal continued to build guns for the Allied forces by moving their production line to a John Inglis and Company plant in Canada, where the name was changed to "Hi Power". The name change was kept even after production returned to Belgium. The pistol is often referred to as an HP or BHP, and the te ...

Gun Safety
Gun safety is the study and practice of using, transporting, storing and disposing of firearms and ammunition, including the training of gun users, the design of weapons, and formal and informal regulation of gun production, distribution, and usage, for the purpose of avoiding unintentional injury, illness, or death. This includes mishaps like accidental discharge, negligent discharge, and firearm malfunctions, as well as secondary risks like hearing loss, lead poisoning from bullets, and pollution from other hazardous materials in propellants and cartridges. There were 47,000 unintentional firearm deaths worldwide in 2013. History Accidental explosions of stored gunpowder date to the 13th century in Yangzhou, China. Early handheld muskets using matchlock or wheel lock mechanisms were limited by poor reliability and the risk of accidental discharge, which was improved somewhat by the introduction of the flintlock, though unintentional firing continued to be a serious draw ...

Semi-automatic Firearm
A semi-automatic firearm, also called a self-loading or autoloading firearm (fully automatic and selective fire firearms are also variations on self-loading firearms), is a repeating firearm whose action mechanism ''automatically'' loads a following round of cartridge into the chamber (self-loading) and prepares it for subsequent firing, but requires the shooter to ''manually'' actuate the trigger in order to discharge each shot. Typically, this involves the weapon's action utilizing the excess energy released during the preceding shot (in the form of recoil or high-pressure gas expanding within the bore) to unlock and move the bolt, extracting and ejecting the spent cartridge case from the chamber, re-cocking the firing mechanism, and loading a new cartridge into the firing chamber, all without input from the user. To fire again, however, the user must actively release the trigger, allow it to "reset", before pulling the trigger again to fire off the next round. As a result, eac ...

Half-cock
Half-cock is when the position of the hammer of a firearm is partially—but not completely—cocked. Many firearms, particularly older firearms, had a notch cut into the hammer allowing half-cock, as this position would neither allow the gun to fire nor permit the hammer-mounted firing pin to rest on a live percussion cap or cartridge. The purpose of the half-cock position has variously been used either for loading a firearm, as a safety mechanism, or for both reasons. The still commonly used English expression of " going off half-cocked" derives from failing to complete the cocking action, leading to the weapon being unable to fire. This is often used to describe someone acting prematurely, as in the case of one preparing to shoot their weapon without having set the firearm into "full-cock" position. Early examples Early flintlocks had required a half-cock position to prime the pan, in preparation for firing the firearm, after loading the main chamber. Some other early type ...

Gun Control Act Of 1968
The Gun Control Act of 1968 (GCA or GCA68) is a U.S. federal law that regulates the firearms industry and firearms ownership. Due to constitutional limitations, the Act is primarily based on regulating interstate commerce in firearms by generally prohibiting interstate firearms transfers except by manufacturers, dealers and importers licensed under a scheme set up under the Act. The GCA was signed into law by President Lyndon B. Johnson on October 22, 1968, and is Title I of the U.S. federal firearms laws. The National Firearms Act of 1934 (NFA) is Title II. Both GCA and NFA are enforced by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). GCA repealed the Federal Firearms Act of 1938, though many of its provisions were reenacted as part of the GCA, which revised the FFA and its predecessor, the National Firearms Act of 1934 (NFA). History The bill was initially prompted by the assassination of U.S. President John F. Kennedy in 1963. The President was shot and ki ...
