A pistol is a type of handgun, characterized by a barrel with an integral chamber. The word "pistol" is derived from the Middle French pistolet, meaning a small gun or knife, and first appeared in the English language c. 1570 when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term to describe any type of handgun, inclusive of revolvers and the pocket-sized derringers.
