The Definition of Luger
American name for the German "Parabellum" semiautomatic pistol introduced in 1900.
The Parabellum was designed by Georg Luger, and based on the earlier Borchardt pistol.
The official German military nomenclature was "Pistole '08" or "Po8." At first, it was chambered for the 7.65mm Parabellum round.
Soon, it was modified to use the 9mm Parabellum cartridge, which is what most people refer to today when talking about a 9mm cartridge.
"Luger" is now a trademark owned by the Stoeger Arms Co.
19 Other Firearms Definitions You Need To Know
A type of firearm action which uses a lever located around the trigger guard area,
(often including the trigger guard itself) to load fresh cartridges into the chamber of the barrel when the lever is worked.
A highly sensitive explosive used as a primer compound.
An extra flange behind the bolt handle, at the rear of a bolt action receiver (notably the Mauser Model 1898),
which uses the bolt handle as an extra locking surface in the extremely unlikely event of forward bolt lug failure.
A shotgun shooting sport that combines elements of skeet and trap, and that is designed to simulate field conditions.
An inert ammunition-shaped object, used in practice to simulate misfeeds and other malfunctions. Some folks also use them during dry fire practice to cushion the firing pin as it strikes.
A small metal explosive-filled cup which is placed over the nipple of a percussion firearm. As the cap is struck by the hammer, it explodes and sends a flame through the flashhole in the nipple to the main powder charge.
A smooth, sometimes contoured plate, within a magazine, at the top of a spring, across which cartridges slide when being loaded into a chamber.
A device used (usually set on a counter) to support a shooters arms and/or hands to help make steadier shots.
A metal jacketed bullet design in which the nose of the core of the bullet is exposed to ensure the expansion of the bullet upon impact.
Often abbreviated "JSP" or "SP." They tend to expand more slowly than a Hollow Point bullet and are used where deeper penetration and expansion are needed.
A 1/60th part of a degree, the unit of measure used in adjusting rifle sights.
As it turns out conveniently, a minute of angle translates almost exactly to one inch at 100 yards
(actually 1.047 inches), to two inches at 200 yards and three inches at 300 yards
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.
A firearm that automatically loads the next cartridge to be fired into the chamber either upon the pull of the trigger in an open bolt design or upon the firing of the previous round in a close bolt design.
Autoloader should not be confused with Automatic or Semi-Automatic since the term Autoloader only applies to how the next round is chambered not
how many rounds can be fired per trigger pull.
All Automatic and Semi-Automatic firearms are autoloaders. Revolvers, bolt action, lever action and pump action firearms are not autoloaders.
The steel skeleton of the forend (above), into which any moving parts are fitted and which mates to and revolves about the action knuckle when the gun is opened.
A volume of fire delivered by a military unit. Incorrectly used by the media to mean the ability of a small arm to be discharged many times without reloading.
Recoil operation is an operating mechanism used in locked-breech, autoloading firearms. As the name implies, these actions use the force of recoil to provide energy to cycle the action.
A concept created by eminent gun writer Col. Jeff Cooper. A scout rifle, generally, is a bolt action carbine firing a
medium power round suitable for taking large game (e.g., .308), fitted with a long eye-relief telescopic sight mounted on the barrel, and a back up set of iron sights.
From the Latin for "more."
A term indicating a relatively heavily loaded metallic cartridge or shotshell and a gun safely constructed to fire it.
It generally indicates a round which cannot be interchanged with other loadings of the same caliber (for example, a .22 Magnum shell does not fit within a firearm designed to fire .22 Long Rifle ammunition).
A type of iron sights that glow or shine in the dark, intended for use in low light conditions. Some night sights consist of tiny tubes of tritium, while others use a phosphorus paint.
An early form of muzzle-loading revolver wherein, instead of the current practice of having one barrel mated to a multi-chambered rotating cylinder,
multiple joined barrels revolve together around a central axis.
