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 first Uzi submachine gun was designed by Major Uziel Gal in the late 1940s. The prototype was finished in 1950. First introduced to IDF special forces in 1954, the weapon was placed into general issue two years later. The Uzi has found use as a personal defense weapon by rear-echelon troops, officers, artillery troops and tankers, as well as a frontline weapon by elite light infantry assault forces.
The Uzi has been exported to over 90 countries. Over its service lifetime, it has been manufactured by Israel Military Industries, FN Herstal, and other manufacturers. From the 1960s through the 1980s, more Uzi submachine guns were sold to more military, law enforcement and security markets than any other submachine gun ever made.

Military variants
The Mini Uzi is a smaller version of the regular Uzi, first introduced in 1980. The Mini Uzi is 600 mm (23.62 inches) long or 360 mm (14.17 inches) long with the stock folded. Its barrel length is 197 mm (7.76 inches), its muzzle velocity is 375 m/s (1230 f/s) and its effective range is 100 m. It has a greater automatic rate of fire of 950 rounds per minute due to the shorter bolt. Its weight is approximately 2.7 kg (6.0 lb). This version was used in an August 2014 accidental shooting of a range instructor by a nine-year-old girl in Arizona.
The Micro Uzi is an even further scaled down version of the Uzi, introduced in 1986. The Micro Uzi is 486 mm (19.13 in) long, reduced to 282 mm (11.10 in) with the stock folded and its barrel length is 117 mm. Its muzzle velocity is 350 m/s (1148 f/s) and its cyclic rate of fire is 1,200 rpm. It weighs slightly over 1.5 kg (3.3 lb).
The Uzi Pro, an improved variant of the Micro Uzi, was launched in 2010 by Israel Weapon Industries Ltd. (I.W.I.), formerly the magen (“small arms”) division of Israel Military Industries. The Uzi Pro is a blowback-operated, select-fire, closed-bolt submachine gun with a large lower portion, comprising grip and handguard, entirely made of polymer to reduce weight; the grip section was redesigned to allow two-handed operation and facilitate control in full-automatic fire with such a small-sized firearm. The Uzi Pro features three Picatinny rails, two at the sides of the barrel and one on the top for optics, the cocking handle having been moved on the left side. The new weapon weighs 2.32 kg and has a length of 529 mm with an extended stock, and 30 cm while collapsed. It has been purchased by the IDF in limited numbers for evaluation and it is yet to be decided whether or not to order additional units for all of its special forces
