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. It was a common sight in the media of the time, being used by both law enforcement officers and criminals. The Thompson submachine gun was also known informally as the "Tommy Gun", "Annihilator", "Chicago Typewriter", "Chicago Piano", "Chicago Style", "Chicago Organ Grinder", "Trench Broom", "Trench Sweeper", "The Chopper", and simply "The Thompson".

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 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 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 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 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.
Personal defense weapons (PDWs) are a class of compact selective fire, magazine-fed, submachine gun like firearms – essentially a hybrid between a submachine gun and compact assault rifle. Most PDWs fire a small-caliber, high-velocity bottleneck cartridge, resembling a small or shortened intermediate rifle cartridge. This gives the PDW better range, accuracy and armor-penetrating capability than submachine guns, which fire pistol-caliber cartridges.
