A gun holder that may be strapped to a human body, or affixed to the inside of a pack or bag, or dropped into a pocket.
A holster serves to protect the gun's mechanisms and finish, to provide security by covering the trigger so it cannot be pulled inadvertently,
and to present the grip of the gun at a constant angle for easy access. Some holsters also serve to obscure the outline of the
gun so it may be more easily concealed. Typically made from leather or in plastic.
A handgun-style fully automatic or burst-mode firearm.
A machine pistol is not the same thing as a Submachine Gun
A rifle projectile made with the tip of the bullet open as a means of increasing accuracy as
compared to standard military bullets that are made with a closed tip and an open base.
The are not designed to expand like a hollow point bullet but may fragment.
To shoot while standing and without bracing against anything. Sometimes it can also mean to shoot with your non-dominant hand.
In the Weaver stance,
the body is bladed partly sideways in relation to the target rather than squared towards it (think boxing or martial arts fighter stance).
The elbows are flexed and pointed downward. The strong-side arm is slightly straighter than the weak-side arm.
Even though the legs are not square to tharget, the hips should be square to the target. The feet should be pointed at the target.
The shooter pushes out with the gun hand, while the weak hand pulls back.
This produces a push-pull tension which is the chief defining characteristic of the Weaver stance.
Not really a gun at all. During the U.S. Civil War,
both sides would take tree branches or tree trunks, paint them black, and position them so that they appeared to be rifles or artillery pieces.
By doing so, they could fool the other side into believing that they had more artillery than they really did.
The science of cartridge discharge and the bullet's flight. Internal ballistics deals with what happens inside of a firearm upon discharge.
External ballistics is the study of a projectile's flight, and terminal ballistics is the study of the impact of a projectile.
The thumb-piece on the top rear of the hammer that enables it to be manually drawn back to full cock.
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF, BATF, and BATFE) is a federal law enforcement organization within the United States Department of Justice. Its responsibilities include the investigation and prevention of federal offenses involving the unlawful use, manufacture, and possession of firearms and explosives; acts of arson and bombings; and illegal trafficking of alcohol and tobacco products. The ATF also regulates via licensing the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce. Many of ATF's activities are carried out in conjunction with task forces made up of state and local law enforcement officers, such as Project Safe Neighborhoods. ATF operates a unique fire research laboratory in Beltsville, Maryland, where full-scale mock-ups of criminal arson can be reconstructed.
Abbreviation for Concealed Carry Permit.
A shoulder-fired long gun which has a rifled barrel.
A small piece of leather or cloth. A patch can refer to the wadding used in loading a muzzle loading firearms or the piece of cloth used to clean a firearm bore.
An unexpected delay between the triggering of a firearm and the ignition of the propellant.
This failure was common in firearm actions that relied on open primer pans, due to the poor or inconsistent quality of the powder.
Modern weapons are susceptible, particularly if the ammunition has been stored in an environment outside of the design specifications.
Reloaded ammunition may also be the cause if not reloaded properly
The substance which imparts movement to the projectile in a firearm. In a firearm, usually powder. In an airgun the propellant is air or Co2
A plain, functional, unembellished firearm used to hunt in rough terrain where one might prefer not to put a more expensive, deluxe grade gun at risk of damage.
Also known as Gun Powder.
A mixture of sulfur, charcoal, and potassium nitrate. It burns rapidly, producing a volume of hot gas made up of carbon dioxide, water, and nitrogen, and a solid residue of potassium sulfide.
Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a
pyrotechnic composition in fireworks.
Modern firearms do not use the traditional black powder described here, but instead use smokeless powder.
The mechanical sighting system which usually comes with the firearm made of metal with no optics.
The housing for a firearm's breech (portion of the barrel with chamber into which a cartridge or projectile is loaded) and firing mechanism.
In semi-automatic handguns and revolvers, this part is typically called the frame.
A fouling shot is a shot fired through a clean bore, intended to leave some residue of firing and prepare the bore for more consistent performance in subsequent shots.
The first shot through a clean bore will behave differently from subsequent shots through a bore with traces of powder residue, resulting in a different point of impact.
