The Uzi is a family of Israeli open-bolt, blowback-operated submachine guns. Smaller variants are considered to be machine pistols. The Uzi was one of the first weapons to use a telescoping bolt design which allows the magazine to be housed in the pistol grip for a shorter weapon. The Mini-Uzi is a smaller version of the regular Uzi, first introduced in 1980. It has a greater automatic rate of fire of 950 rounds per minute due to the shorter bolt.
