Chapman Stance

The Chapman stance uses the same push-pull tension which defines the Weaver, but instead of both elbows being bent, the gun side elbow is held straight and locked in place. Assuming a right-handed shooter, the right arm is punched straight out, while the left elbow is bent and the left hand pulls back to provide tension. As a result of this change, Chapman gets its stability from both muscle and skeletal support. This makes it a little more friendly than Weaver for those who lack upper-body muscle strength.

Slide

The upper portion of a semi-automatic pistol that houses the barrel and contains the breechblock and portions of the firing mechanism. Ejecting the spent case as it moves to the rear and loading a fresh cartridge into the chamber as it moves forward again. As its name states, it slides along tracks in the top of the frame during the recoil process providing the linkage between the breechblock and barrel.

Percussion Cap

Patch Box

Covered compartment in the buttstock of a muzzle-loading rifle used to carry patches or other small items.

Bluing

Also spelled blueing. A passivation process in which steel is partially protected against rust, and is named after the blue-black appearance of the resulting protective finish. True gun bluing is an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (Fe3O4), the black oxide of iron, which occupies the same volume as metallic iron. Bluing is most commonly used by gun manufacturers, gunsmiths and gun owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms.

Bull Barrel

Bull barrels are barrels that are not tapered at all. These very heavy barrels, designed for extreme accuracy, are usually seen on target rifles.

Holster

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.

Energy

The amount of work done by a bullet, expressed in foot pounds.

Primer Ring

Refers to a visible dark ring created by the primers in centerfire ammunition around the firing pin hole in the frame after much use.

Speed Strip
