Terminology

cap gun

A cap gun, cap pistol, or cap rifle is a toy gun that creates a loud sound simulating a gunshot and smoke when a small percussion cap is ignited by a hammer hitting the gunpowder. Cap guns were originally made of cast iron, but after World War II were made of zinc alloy, and most newer models are made of plastic. • Illustration — An orange-tipped cap gun with its hammer drawn back Cap guns get their name from the small discs of shock-sensitive explosive compounds (roughly 1.4 to in diameter) that provide the noise and smoke, effectively the same as the Maynard tape primer and percussion caps used in real firearms of the mid to late 1800s but usually smaller and made from cheap plastic or paper. Some are arranged in plastic rings of eight or twelve.
