Penetration

The distance travelled by a projectile from the point where it strikes the target to the point where it stops.

Trigger Break

The point at which the trigger allows the hammer to fall, or releases the striker, so that the shot fires. The ideal trigger break is sudden and definite. "Like a glass rod" is the cliche term shooters use to describe the ideal crisp, clean break.

Annulus

A tiny circular recess at the base of a cartridge case surrounding the primer pocket. Recoil from fired cartridges invariably impress a discernable ring on the breech or bolt face of a firearm, providing some evidence of the amount of use it has seen.

Fouling Shot

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.

Barrel

A tube, usually metal, through which a controlled explosion or rapid expansion of gases are released in order to propel a projectile out of the end at a high velocity. It is the tube through which the bullet or shot travels. The barrel serves the purpose of providing direction and velocity to the bullet.

Peep Sight

An alternate name for Aperture Sight.

Glock

The Glock pistol, sometimes referred to by the manufacturer as a Glock "Safe Action" Pistol, is a series of polymer-framed, short recoil operated, locked breech semi-automatic pistols designed and produced by Glock Ges.m.b.H., located in Deutsch-Wagram, Austria.

Weapon

Anything that can be used in an offensive attack or in defense of an offensive attack. Guns are not necessarily weapons.
A gun can be used as a weapon, but so can a pencil, fist, car, a wad of paper or any other object used to attack or retaliate against an offensive attack. Even words can be used as a weapon.
Guns and other objects should be always called what they are; gun, rifle, pistol, pencil, knife, tomato or whatever they are. They should never be referred to as a weapon, EVER.
Some examples of the proper usage for the word "weapon" would be:
"One weapon used in the attack against the left flank was dirt clods".
"The marshmallow gun was the weapon of choice used in the accounting vs marketing skirmishes."
"The liberal leftists use words and restrictive controlling laws as weapons against the freedom of the people."

Holographic Weapon Sight

Overbore Capacity

Is that combination of caliber, barrel length, bullet weight, and case volume which does not allow the complete burning of the charge of ballistically correct powder within the volume of case and barrel.

Safe

A firearm is said to be on safe when its safety is engaged and off safe when it is ready to fire.

Bolt

The mechanism of some firearms that holds the cartridge in place during the firing process. It must be moved out of the way to load and unload the gun; this action may be manually performed by the shooter pulling back on an exterior knob called the bolt handle and then sending it forward again, or the action may be performed by other moving parts within the firearm. When the user must move the bolt manually, the firearm is called a bolt-action firearm.
