The term 'quick-firing gun' can be summarized by the three letter acronym UZI. The Uzi is a family of Israeli open-bolt, blowback-operated submachine guns. It was first developed in the late 1940s by Major Uziel Gal and manufactured by Israel Military Industries. It has become one of the most popular submachine guns in the world due to its compact size, ease of use, and relatively low production cost.
