'''Guns''' are tools generally designed for firing bullets in a controlled manner.  They have traditionally been used for two purposes: firing bullets at people, and threatening to fire bullets at people.  Thus, a gun is considered a [[weapon]], though technically, the bullet is the weapon, unless the gun itself is used as a club, or as a spear if it has a [[bayonet]] attached.

There are many types of guns.  Some guns fire small bullets.  Some guns fire big bullets.  Some guns fire ''very'' big bullets; these are generally called [[cannon]]s. Some guns fire a bunch of small bullets all at once; these are generally considered [[shotgun]]s. Some guns fire very fast, requiring only a single pull of the trigger; these are generally considered [[machine gun]]s.  Some guns fire very slowly, requiring a full barrel cleaning and reloading before firing again. Most [[handgun]]s are semi-automatic, meaning that they fire a single round with a single pull of the trigger, and require reloading only after its built-in supply is depleted.

The three main types of firearms today are bolt-operated, semi-automatic, and automatic weapons. In a bolt-action weapon, each new round must be chambered manually, by moving the breech to eject the empty casing. In semi-automatic weapons, each pull of the trigger fires a bullet. In fully automatic weapons, bullets will be fired as long as the trigger is depressed until either the trigger is released, or the ammunition is exhausted.

[[Science fiction]], such as [[Star Trek]], has postulated many different types of energy weapons.  These are guns that fire beams, waves, or packets of energy.  Some energy guns can be set to stun, not to wound or kill.  A real-life applications of this is the [[taser]].
