A gun is a normally tubular weapon or other device designed to discharge projectiles or other material. The projectile may be solid, liquid, gas or energy and may be free, as with bullets and artillery shells, or captive as with Taser probes and whaling harpoons. The means of projection varies according to design but is usually effected by the action of gas pressure, either produced through the rapid combustion of a propellant or compressed and stored by mechanical means, operating on the projectile inside an open-ended tube in the fashion of a piston. The confined gas accelerates the movable projectile down the length of the tube imparting sufficient velocity to sustain the projectile's travel once the action of the gas ceases at the end of the tube or muzzle. Alternatively, acceleration via electromagnetic field generation may be employed in which case the tube may be dispensed with and a guide rail substituted.
Barrel types include rifled—a series of spiraled grooves or angles within the barrel—when the projectile requires an induced spin to stabilize it, and smoothbore when the projectile is stabilized by other means or rifling is undesired or unnecessary. Typically, interior barrel diameter and the associated projectile size is a means to identify gun variations. Bore diameter is reported in several ways. The more conventional measure is reporting the interior diameter (bore) of the barrel in decimal fractions of the inch or in millimetres. Some guns—such as shotguns—report the weapon's gauge (which is the number of shot pellets having the same diameter as the bore produced from one English pound (454g) of lead) or—as in some British ordnance—the weight of the weapon's usual projectile.
A gun projectile may be a simple, single-piece item like a bullet, a casing containing a payload like a shotshell or explosive shell, or complex projectile like a sub-caliber projectile and sabot. The propellant may be air, an explosive solid, or an explosive liquid. Some variations like the Gyrojet and certain other types combine the projectile and propellant into a single item.
The term gun may refer to any sort of projectile weapon from large cannons to small firearms including those that are usually hand-held (handgun). The word gun is also commonly used to describe objects which, while they are not themselves weapons, produce an effect or possess a form which is in some way evocative of a handgun or long gun.
In contemporary military and naval parlance the term gun has a very specific meaning and refers solely to any large-calibre, direct-fire, high-velocity, flat-trajectory artillery piece employing an explosive-filled hollowed metal shell or solid bolt as its primary projectile. This later usage contrasts with large-calibre, high-angle, low-velocity, indirect-fire weapons such as howitzers, mortars, and grenade launchers which invariantly employ explosive-filled shells.
