The Uzi has been exported to over 90 countries. 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 military, law enforcement and security agencies than any other submachine gun ever made.
The Uzi uses an open-bolt, blowback-operated design, quite similar to the Jaroslav Holecek-designed Czech ZK 476 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.
The non-reciprocating charging handle on the top of the receiver cover is used to retract the bolt. Variants have a ratchet safety mechanism which will catch the bolt and lock its movement if it is retracted past the magazine, but not far enough to engage the sear. When the handle is fully retracted to the rear, the bolt will cock on the sear mechanism and the handle and cover are released to spring fully forward under power of a small spring. The cover will remain forward during firing since it does not reciprocate with the bolt. The military and police versions will fire immediately upon chambering a cartridge as the Uzi is an open bolt weapon.
There are two external safety mechanisms on the Uzi. The first is the three-position selector lever located at the top of the grip and behind the trigger group. The rear position is "S", or "safe", which locks the sear and prevents movement of the bolt.
The second external safety mechanism is the grip safety, which is located at the rear of the grip. It is meant to help prevent accidental discharge if the weapon is dropped or the user loses a firm grip on the weapon during firing.
The trigger mechanism is a conventional firearm trigger, but functions only to control the release mechanism for either the bolt (submachine gun) or firing pin holding mechanism (semi-auto) since the Uzi does not incorporate an internal cocking or hammer mechanism. While the open-bolt system is mechanically simpler than a closed-bolt design (e.g. Heckler & Koch MP5), it creates a noticeable delay between when the trigger is pulled and when the gun fires.
The magazine release button or lever is located on the lower portion of the pistol grip and is intended to be manipulated by the non-firing hand. The paddle-like button lies flush with the pistol grip in order to help prevent accidental release of the magazine during rigorous or careless handling.
When the gun is de-cocked the ejector port closes, preventing entry of dust and dirt. Though the Uzi's stamped-metal receiver is equipped with pressed reinforcement slots to accept accumulated dirt and sand, the weapon can still jam with heavy accumulations of sand in desert combat conditions when not cleaned regularly. The magazine must be removed prior to de-cocking the weapon.
