The MP5 is a 9mm submachine gun, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar. There are over 100 variants of the MP5, including some semi-automatic versions.
The Thompson submachine gun is an American submachine gun, invented by John T. Thompson in 1918, that became infamous during the Prohibition era, becoming a signature weapon of various police syndicates in the United States.

The Uzi is a family of Israeli open-bolt, blowback-operated submachine guns. Smaller variants are often 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 Magpul FMG-9 is a prototype for a new generation of folding submachine guns, designed by Magpul Industries in 2008. Like other folding machine guns, it would be used for concealed carry and can be disguised as anything from a small package to an extra laptop battery. It is made out of a light-weight polymer material rather than metal, making it very light and easy to carry. It was developed for potential use by personal protection details such as the United States Secret Service. As of 2014 Magpul has indicated no intention of bringing the prototype to production.
The KRISS Vector series are a family of weapons based upon the parent submachine gun design developed by KRISS USA, formerly Transformational Defense Industries (TDI). They use an unconventional delayed blowback system combined with in-line design to reduce perceived recoil and muzzle climb.
The Heckler & Koch UMP is a submachine gun developed and manufactured by Heckler & Koch. The UMP has been adopted by various agencies such as the U.S. Customs and Border Protection. Heckler & Koch developed the UMP as a lighter and cheaper successor to the MP5, though both remain in production.
The STEN was a family of British submachine guns chambered in 9×19mm and used extensively by British and Commonwealth forces throughout World War II and the Korean War. They had a simple design and very low production cost, so they were also effective insurgency weapons for resistance groups.
The Military Armament Corporation Model 10, officially abbreviated as "M10" or "M-10", and more commonly known as the MAC-10, is a compact, blowback operated machine pistol that was developed by Gordon B. Ingram in 1964. It is chambered in either .45 ACP or 9mm. A two-stage suppressor by Sionics was designed for the MAC-10, which not only abated the noise created, but made it easier to control on full automatic.
The M3 was an American .45-caliber submachine gun adopted for U.S. Army service on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to produce and lighter, although, contrary to popular belief, it was less accurate. This myth stems from a US Army training film portraying the M3 as more accurate than its counterparts. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser," owing to its visual similarity to the mechanic's tool.
The Scorpion EVO 3 is a 9mm carbine manufactured by Česká zbrojovka Uherský Brod, the select-fire variant designated as A1 being a submachine gun and the semi-automatic variant designated as S1. The EVO 3 designation denotes that the firearm is a third generation of CZ's line of small submachine guns started by the Škorpion vz. 61.
The Sterling submachine gun is a British submachine gun. It was tested with the British Army in 1944–1945 as a replacement for the Sten but it did not start to replace it until 1953. It remained in use until 1994, when it was phased out as the L85A1 assault rifle was phased in.
The MP 18 manufactured by Theodor Bergmann Abteilung Waffenbau was the first submachine gun used in combat. It was introduced into service in 1918 by the German Army during World War I as the primary weapon of the Sturmtruppen, assault groups specialized in trench combat. Although MP 18 production ended in the 1920s, its design formed the basis of most submachine guns manufactured between 1920 and 1960.
