The Uzi prototype was finished in 1950. It was first introduced toIsrael 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.[14] Over its service lifetime, it has been manufactured byIsrael 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.[17]
Uziel Gal, the designer and inventor of the Uzi submachine gun
The Uzi uses anopen-bolt,blowback-operated design, quite similar to the Jaroslav Holeček-designed Czech ZK 476 (prototype only)[18] and the productionSa 23, Sa 24, Sa 25, and Sa 26 series of submachine guns introduced in 1948. The open bolt design exposes the barrel's breech end, improving cooling after 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 atelescoping bolt design, in which the bolt wraps around the breech end of the barrel.[19] This allows the barrel to be moved far back into thereceiver and themagazine to be housed in the pistol grip, allowing for a heavier, slower-firing bolt in a shorter, better-balanced weapon.[17]
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 agrip safety, making it difficult to fire accidentally. However, the protruding vertical magazine makes the gun awkward to fire when prone.[19] The Uzi features a bayonet lug.[20]
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 thesear. When the handle is fully retracted to the rear, the bolt will cock (catch) 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" (S = Sicher or Secure on the MP2), 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.[21] The magazine must be removed prior to de-cocking the weapon.
Uzi with a detachable wooden stockUzi with a folding stock
There are different stocks available for the Uzi proper.[22] There is a wooden stock with a metal buttplate that comes in three similar variations that were used by the IDF. The first version had a flat butt and straightcomb and had hollows for a cleaning rod and gun oil bottle. The second had an angled butt and a straight comb and no hollows. The third had an angled butt and curved comb and no hollows; a polymer version is currently available from IMI. The wooden stocks originally had a quick-release base but the ones sold in the United States often had a permanent base for legal reasons, as detachable stocks on pistols or other short-barreled weapons upgrade the weapon toNFA status.[23][24]
Choate made an aftermarket polymer stock with a rubber butt-pad that had a flat butt, a straight comb, and a permanent base.
In 1956,[25] IMI developed a downward-folding twin-strut metal stock with two swivelling sections that tuck under the rear of the receiver. The Mini Uzi has a forward-folding single-strut metal stock that is actually an inch longer than the Uzi's. Its buttplate can be used as a foregrip when stowed. The Micro Uzi has a similar model.
The original box magazines for the 9mm Uzi had a 25-round capacity. Experimental 40- and 50-round extended magazines were tried but were found to be unreliable. A 32-round extended magazine was then tried and was later accepted as standard. The Mini Uzi and Micro Uzi use a shorter 20-round magazine. Available extended magazines include 40-, and 50-round magazines. Other high-capacity aftermarket magazines exist such as the Vector Arms 70-round and Beta Company (Beta C-Mag) 100-rounddrums.
The .45 ACP Uzi used a 16- or 22-round magazine, while the .45 ACP Micro Uzi and Mini Uzi used a 12-round magazine. A conversion kit by Vector Arms allowed the .45-caliber Uzi to use the same 30-round magazines as theM3 "Grease Gun".[8]: 20–25
The Uzi was available with caliber conversion kits in .22 LR or.41 AE. The operator just has to change the barrel, bolt and magazine. The .22 LR had 20-round magazines; the original IMI kit used a barrel insert while the aftermarket Action Arms kit used a full replacement barrel. The .41 AE also had a 20-round magazine; since it has the same bolt face as the 9×19mm Parabellum, only the barrel and magazine needed to be changed.[8]: 20–25
IMI also manufactured a .45ACP conversion kit both in full auto/open bolt with a 10.2" barrel for the 9mm SMG and a semi only/closed bolt with a 16" barrel for the carbine version. Magazine capacity is limited, with 2 sizes of 16 and 10 rds each.

The Uzi submachine gun was designed by Captain (later Major)Uziel Gal of theIsrael Defense Forces (IDF) following the1948 Arab–Israeli War. The weapon was submitted to the Israeli Army for evaluation and won out over more conventional designs due to its simplicity and economy of manufacture. Gal did not want the weapon to be named after him, but his request was ignored. The Uzi was officially adopted in 1951. First introduced to IDF special forces in 1954, the weapon was placed into general issue two years later. The first Uzis were equipped with a short, fixed wooden buttstock, and this is the version that initially saw combat during the 1956 Suez Campaign. Later models would be equipped with a folding metal stock.[21]
The Uzi was used as apersonal 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's compact size and firepower proved instrumental in clearing Syrian bunkers and Jordanian defensive positions during the 1967Six-Day War. Though the weapon was phased out of frontline IDF service in the 1980s, some Uzis and Uzi variants were still used by a few IDF units until December 2003, when the IDF announced that it was retiring the Uzi from all IDF forces.[26] It was subsequently replaced by the fully automaticMicro Tavor.
In general, the Uzi was a reliable weapon in military service. However, even the Uzi fell victim to extreme conditions of sand and dust. During the Sinai Campaign of theYom Kippur War, IDF Army units reaching theSuez Canal reported that of all their small arms, only the 7.62mmFN MAG machine gun was still in operation.[27]
The Uzi proved especially useful formechanized infantry needing a compact weapon and for infantry units clearingbunkers and other confined spaces. However, its limited range and accuracy in automatic fire (approximately 50 m (160 ft)) could be disconcerting when encountering enemy forces armed with longer-range small arms, and heavier support weapons could not always substitute for a longer-ranged individual weapon. These failings eventually caused the phasing out of the Uzi from IDF front-line assault units.[26]
The Uzi has been used in various conflicts outside Israel and the Middle East during the 1960s and 1970s. Quantities of 9 mm Uzi submachine guns were used by Portuguese cavalry, police, and security forces during thePortuguese Colonial Wars in Africa.[21]
Total sales of the weapon to date (end of 2001) has netted IMI over 2 billion US dollars, with over 90 countries using the weapons either for their armed forces or in law enforcement.[17]
TheRoyal Netherlands Army first issued the Uzi in 1956. It was the first country other than Israel to use it as a service weapon. Their models are distinct in that they have a wooden stock (made to their specifications) that is more angular, an angled butt and a curved comb, and is 2 inches longer than the IDF model. The wooden stock versions were mainly used by theRoyal Netherlands Navy and theMarine Corps. The Army andAirforce received the metal foldable stock versions as replacement. No bayonets were issued.
The GermanBundeswehr (especially its tank crews) used the Uzi since 1959 under the designation MP2.[28][29] It replaced theMP1 (Beretta M1938/49) andThompson M1 in service. The MP2 was fitted with the IDF-style wooden stock and the later MP2A1 was fitted with the metal folding stock. It can be recognized by its distinctive three-position "DES" selector switch: "D" for "Dauerfeuer" ("continuous-fire", or "automatic"), "E" for "Einzelfeuer" ("single-fire", or "semi-automatic"), and "S" for "Sicher" ("secure", or "safe"). It was replaced with theHeckler & Koch MP7 Personal Defense Weapon in 2007.[29] Most of the Uzis used in Germany consisted of receivers with Israeli markings and grips made by FN.[29]
InRhodesia, the Uzi was produced under license from 1976 until the fall of Rhodesia in 1980. It was made from Israeli-supplied (and later Rhodesian-made) components.
TheUnited States Secret Service used the Uzi as their standard submachine gun from the 1960s until the early 1990s, when it was phased out and replaced with theHeckler & Koch MP5 andFN P90. WhenPresident Ronald Reagan was shot on March 30, 1981, Secret Service Special Agent Robert Wanko pulled an Uzi out of a briefcase and covered the rear of the presidential limousine as it sped to safety with the wounded president inside.[17]
A Mini UziArgentine special forces with a Micro UziUzi Pro
The standard Uzi has a 10-inch (250 mm) barrel. It has a rate of automatic fire of 600 rounds per minute (rpm) when chambered in9mm Parabellum; the.45 ACP model's rate of fire is slower at 500 rpm.[21]
TheMini Uzi is a smaller version of the regular Uzi, first introduced in 1980. The Mini Uzi is 600 mm (24 in) long or 360 mm (14 in) long with the stock folded. Its barrel length is 197 mm (7.8 in), its muzzle velocity is 375 m/s (1,230 ft/s) and its effective range is 100 m (330 ft). 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).[21]
TheMicro Uzi is an even further scaled down version of the Uzi, introduced in 1986. The Micro Uzi is 486 mm (19.1 in) long, reduced to 282 mm (11.1 in) with the stock folded, and its barrel length is 117 mm (4.6 in). It has a closed bolt compared to its original counterpart.[34] Its muzzle velocity is 350 m/s (1,100 ft/s) and its cyclic rate of fire is 1,200 rpm. It weighs slightly over 1.5 kg (3.3 lb).[21]
TheUzi Pro, an improved variant of the Micro Uzi, was launched in 2010 byIsrael Weapon Industries Ltd. (I.W.I.), formerly themagen ("small arms") division ofIsrael 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 of such a small-sized firearm. The Uzi Pro features fourPicatinny rails, two at the sides of the barrel, which can be removed, one below the barrel for the addition of foregrips and one on the top for optics. The under barrel rail is often shown with a specialised foregrip which attaches to the pistol grip to form a handguard. In addition, the cocking handle has been moved to the left side.[35] The new weapon weighs 2.32 kg (5.1 lb) and has a length of 529 mm (20.8 in) with an extended stock,[36] and 300 mm (12 in) while collapsed. As of 2011 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.[36][37]
The Uzi carbine is similar in appearance to the Uzi submachine gun. The Uzicarbine is fitted with a 400-millimetre (16 in) barrel, to meet the minimum rifle barrel lengthrequirement for civilian sales in the United States. A small number of Uzi carbines were produced with the standard length barrel for special markets. It fires from a closed-bolt position in semi-automatic mode only and uses a floating firing pin as opposed to a fixed firing pin.[27] The FS-style selector switch has two positions (the automatic setting was blocked): "F" for "fire" (semi-auto) and "S" for "safe". Uzi carbines are available in .22 LR, 9mm, .41 AE, and .45 ACP calibers.
The Uzi carbine has two main variants, the Model A (imported from 1980 to 1983) and the Model B (imported from 1983 until 1989). The Type A was the same as the fully automatic Uzi, while the Type B had a firing pin safety and improved sights and sling swivels. These two variants were imported and distributed by Action Arms.[27]
The American firm Group Industries made limited numbers of a copy of the Uzi "B" model semiauto carbine for sale in the US along with copies of the Uzi submachine gun for the U.S. collectors' market. After registering several hundred submachine guns transferable to the general public through a special government-regulated process, production was halted due to financial troubles at the company. Company assets (including partially made Uzi submachine guns, parts, and tooling) were purchased by an investment group later to become known as Vektor Arms. Vektor Arms built and marketed numerous versions of the Uzi carbine and the Mini Uzi.[38] As of 2024, average prices can be over $25,000.00 USD.[39]
Today, while the civilian manufacture, sale and possession of post-1986 select-fire Uzi and its variants is prohibited in the United States, it is still legal to sell templates, tooling and manuals to complete such conversion. These items are typically marketed as being "post-sample" materials for use by federal firearm licensees for manufacturing/distributing select-fire variants of the Uzi to law enforcement, military and overseas customers.[40]
TheMini Uzi carbine is similar in appearance to the Mini Uzi machine pistol. The Mini Uzi carbine is fitted with a 500-millimetre (20 in) barrel, to meet the minimum rifle overall length requirement for civilian sales in the United States. It fires from a closed-bolt position in semi-automatic mode only.[27]
TheUzi pistol is asemi-automatic, closed bolt, and blowback-operated pistol variant. Its muzzle velocity is 345 m/s. It is a Micro Uzi with no shoulder stock or full-automatic firing capability. The intended users of the pistol are various security agencies in need of a high-capacity semi-automatic pistol, or civilian shooters who want a gun with those qualities and the familiarity of the Uzi style. It was introduced in 1984 and produced until 1993.[21]
TheUzi Pro pistol is a current version of the Uzi pistol. It has rails on the top and bottom, and there is an optional stabilizing brace. Unlike any other Uzi variant, the Uzi Pro pistol has a side charging handle, rather than a top charging handle, and has a three-stage safety. There are three safeties on the Uzi Pro pistol: a thumb safety, a grip safety, and a firing pin block. This model was intended for law enforcement and civilian use, due to the compact size, rails, and a semi-automatic rate of fire. Unlike other Uzi variants, the Uzi Pro pistol is only chambered for 9×19 Parabellum.
TheArma Grupa Strojnica ERO (Arms Group "ERO machine-gun") was a Croatian Uzi clone made locally byArma Grupa of Zagreb during the Yugoslav War. It was made entirely from steel stampings, causing it to weigh more (3.73 kg (8.2 lb)).[41] The only difference from the Uzi is the selector switch, which is marked "R" (Rafalno {"burst"}, for full automatic fire), "P" (Pojedinačno, for single shot) and "Z" (Zaključan {locked}, for safe) and itsrate of fire is 650 rounds per minute. It uses the 32-round magazine as standard, but can use any 9mm Uzi-interface magazine of 25 rounds or larger.
The Strojnica Mini ERO is a clone of the Micro Uzi; it differs in that it had a heavy-gauge folding wire stock like theSkorpion Machine Pistol. It weighs 2.2 kilograms (4.9 lb) unloaded and is 545.5 millimetres (21.48 in) overall with the folding stock extended and 250 millimetres (9.8 in) with the stock folded. It uses the 20-round Mini Uzi magazine.
The EROs were used by the Croatians as early as 1992.[42]
The BA93 and BA94 are Myanmar made clones of the Uzi.[43] Production started inMyanmar after 1991 when an Israeli delegation visited the country and supplied theTatmadaw with Uzis.[44][45] It also included the rights to manufacture the Uzi under license.[46]
The BA93 is based on the Uzi, but with a longer barrel and fixed stock.[47] It was introduced in 1993.[46] It is commonly seen with Myanmar soldiers and special forces units operating in commando or VIP protection operations.[46]
The BA94 was introduced in 1994.[48] Improvements made include moving the charging handle from the top to the left with a shorter barrel.[46] This model is mostly seen with Myanma police forces.[46]
Norinco of China manufactures an unlicensed copy of the Uzi Model B that is sold as the Model 320.[49] Early versions were marked "POLICE Model" in English. Modifications were made to avoid the US Assault Weapon Import Ban: the folding stock was replaced with a woodenthumbhole stock, the barrel nut was welded in place, and the bayonet lug was removed.[50] The gun had a grayparkerized finish,[49] a 410 millimetres (16 in) carbine-length barrel and is 800 millimetres (31 in) overall.
The Zastava M97 is a Serbian clone of the Mini Uzi.[52] Two variants consist of the M97 with an 8 in (200 mm) barrel and the M97K with a 6.5 in (170 mm) barrel and no folding stock with a vertical foregrip permanent attached.[52][53]
Myanmar: Locally produced under model number BA93 (wooden stock) and BA94 with, used mainly by Myanmar Police Force and Special Operation Task Force.[56]
Vietnam[55] - People's Army news (Báo Quân đội nhân dân) informed that Technical Department of Special Operation Command (Sapper) had a project to design and manufacture calibration device for MARS attached on Micro Uzi.[71]
Italy: The Mini Uzi variant results by official schedules to be in the inventories of theItalian National Police.[77] A local version called theType 821-SMG was manufactured from 1984 to 1989 by theSOCIMI - Società Costruzioni Industriali Milano, S.p.A. inMilan.
United States:[27][70] From 1968 to 1973, the CIA bought 3,000 Uzis for use in Southeast Asia byDirect Action operatives and Special Forces troops. From the 1960s to 1990s, The US Secret Service's VIP details used a chopped-down model that could be concealed in a briefcase.
