Background

The Uzi ,  Ūzi; officially cased as UZI) is a family of Israeli open-bolt, blowback-operated submachine guns and machine pistols first designed by Major Uziel “Uzi” Gal in the late 1940s, shortly after the establishment of the State of Israel. It is one of the first weapons to incorporate a telescoping bolt design, which allows the magazine to be housed in the pistol grip for a shorter weapon.

The Uzi prototype was finished in 1950. It was first introduced to Israel Defense Forces (IDF) special forces in 1954, and the weapon was placed into general issue two years later. The IDF supplied Uzis to rear-echelon troops, officers, artillery troops and tank crews, 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 to the 1980s, more Uzi submachine guns were sold to more military, law enforcement and security markets than any other submachine gun ever made.

Technical Information

Design

The Uzi uses an open-bolt, blowback-operated design, quite similar to the Jaroslav Holeček-designed Czech ZK 476 (prototype only) and the production Sa 23, Sa 24, Sa 25, and Sa 26 series of submachine guns. The open bolt design exposes the breech end of the barrel, and improves cooling during periods of continuous fire. However, it means that since the bolt is held to the rear when cocked, the receiver is more susceptible to contamination from sand and dirt. It uses a telescoping bolt design, in which the bolt wraps around the breech end of the barrel. This allows the barrel to be moved far back into the receiver and the magazine to be housed in the pistol grip, allowing for a heavier, slower-firing bolt in a shorter, better-balanced weapon.

The weapon is constructed primarily from stamped sheet metal, making it less expensive per unit to manufacture than an equivalent design machined from forgings. With relatively few moving parts, the Uzi is easy to strip for maintenance or repair. The magazine is housed within the pistol grip, allowing for intuitive and easy reloading in dark or difficult conditions, under the principle of “hand finds hand”. The pistol grip is fitted with a grip safety, making it difficult to fire accidentally. However, the protruding vertical magazine makes the gun awkward to fire when prone. The Uzi features a bayonet lug.
