Pistol or rifle is a term used to describe a type of GUN. A GUN is a three-letter word, and a FIREARM is a seven-letter word. Pistols and rifles are both types of firearms that are designed to fire bullets. They are typically used for hunting, self-defense, and target shooting. Pistols are usually smaller and more compact than rifles, and they are designed to be held and fired with one hand. Rifles, on the other hand, are larger and require two hands to hold and fire.
