The Definition of Combination Gun
A shoulder-held firearm that has two barrels; one rifle barrel and one shotgun barrel.
Most combination guns are of an over/under design (abbreviated as O/U), in which the two barrels are stacked vertically on top of each other,
but some combination guns are of a side-by-side design (abbreviated as SxS), in which the two barrels sit beside each other.

Synonymous with pistol. A small, short-barreled firearm designed to be fired while held in one or both hands, possibly small enough to be concealed on the person, rather than while braced against the shoulder.

Abbreviation for Caliber.
Also called black powder, gunpowder is 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. The term gunpowder also refers broadly to any propellant powder.
Modern firearms do not use the traditional gunpowder (black powder) described here, but instead use smokeless powder.
A family of smokeless propellants developed and produced in the United Kingdom from 1889 to
replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low
explosive because of its slow burning rates and consequently low brisance.
The hot gases produced by burning gunpowder or cordite generate sufficient pressure to propel a bullet or shell to its target,
but not enough to destroy the barrel of the firearm, or gun.
A person who can shoot up to the mechanical capability of their weapon.
A fully automatic firearm that fires pistol ammunition.

Circular steel fittings, about 1/2 inch in diameter, screwed into the breech face of a gun and through which the firing pins pass.
Firing pin bushings allow the convenient replacement of broken firing pins. They also allow the renewal of an older gun where, over the decades,
leakage of high-pressure gas from corrosive primers has eroded the breech face around the firing pins; and replacing these bushings with new ones,
slightly oversized can compensate for a situation where proper headspace has been compromised.
A type of curve represented by the curved section of a bullet between its bearing surface and its tip.
The paper filler at the rear of the powder charge of the shotgun shell.
Also call a Muzzle Brake. A device attached to or made as part of a firearms barrel designed to reduce recoil or muzzle movement on firing.
