The Definition of Out of Battery
Out of Battery
A semi-automatic is said to be out of battery when the slide fails to come all the way forward again after the
gun has fired. This condition can be created by a misfeed, a dirty gun, weak springs, the shooter's
thumbs brushing against the slide, riding the slide, or any of several other causes.

Abbreviation for 'Back Up Gun'
Failure of a spent case to completely eject from a semi-automatic firearm. The case usually stands on end while lodged in the ejection port.
Also known as peep sights, range from the ghost ring sight, whose thin ring blurs to near invisibility (hence ghost), to target aperture sights that use large disks or other occluders with pinhole-sized apertures. In general, the thicker the ring, the more precise the sight, and the thinner the ring, the faster the sight.
A matrix of dots, posts or lines, visible inside a rifle's telescopic sight, normally adjustable via exterior knobs for windage and elevation.
After careful adjustment at a known range, the shooter aims the rifle by superimposing this matrix onto the target. With good estimation or range,
cooperation from the wind, a clear eye and a steady hand, he may have a reasonable expectation of hitting his target.
The size of the pellets in a shotgun shell.
The wearing of the portion of the barrel where the gas pressure and heat is highest as the projectile leaves the chamber.
The greater the chamber pressure the more rapid throat erosion occurs which is compounded by rapid firing which heats and weakens the steel.
A specialized facility designed for firearms practice.
Usually a rifle, but not always.
A small-caliber firearm or high-powered air gun primarily used for hunting
non-native or non-game animals such as rats, squirrels, gophers, jackrabbits, marmots, groundhogs, porcupine, opossum, coyote, skunks, weasels,
and other animals considered to be nuisance vermin destructive to native or domestic plants and animals.
Usually only found on black powder muzzle loading rifles and pistols,
pulling the rear (set) trigger converts the front (main) trigger to a light, hair trigger
(too light and sensitive to be carried safely in the field). While the front trigger is always at the ready,
if one has the time, using the set trigger feature may allow for a more accurate long-distance shot.
Operates using its own miniature firing mechanism (sear, spring and hammer) when cocked,
to multiply the force of a pull on the main trigger.
The paper filler at the rear of the powder charge of the shotgun shell.
Helical grooves in the barrel of a gun or firearm, which imparts a spin to a projectile around its long axis.
This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.
Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge,
normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession,
one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge,
but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.
Slang term for a firearm sound suppressor.
A rifle with a relatively short barrel.
The propellant powder used in modern ammunition. It is not an explosive, but rather a flammable solid that burns extremely rapidly releasing a
large volume of gas. Commonly called "gunpowder" and usually made from nitrocellulose, or nitrocellulose and nitroglycerin.
It is classified as a "Flammable Solid" by the Department of Transportation.
The unalienable right of all of the people, stated in the Second Article of The Bill of Rights, to possess and use personally owned firearms for sport, recreation, personal protection, and the defense of the nation.
