Guardians of the Stars
A handgun is a firearm designed to be handheld, in either one or both hands. This characteristic differentiates handguns as a general class of firearms from long guns such as rifles and shotguns (which usually can be mounted against the shoulder).
The two major subtypes are: Revolvers and Pistols. Though other subtypes include derringers, single-shot pistols, semi-automatic pistols, pepperboxes, and machine pistols.
