text: A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long gun (i.e. carbine, rifle, shotgun, submachine gun, or machine gun) which needs to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols, although other handguns such as derringers and machine pistols also see infrequent usage.
