What is the difference between a revolver and a pistol?
A revolver is a multishot firearm, usually a handgun, in which the rounds are held in a revolving cylinder that rotates to fire them through a single barrel. Pistols are smaller, lighter, easier to conceal, faster to bring to bear, and sometimes may have more safety features than other firearms. Generally being an emergency self-defense weapon for use under 25 meters, a handgun bullet neither has the energy of, nor the accuracy of, a bullet shot from a rifle.
