The Thompson 1921, also known as the "Tommy Gun," is an American submachine gun developed by John T. Thompson. Chambered in .45 ACP, it gained notoriety during the Prohibition era, where it was used by both law enforcement and criminal organizations. Its high rate of fire and iconic design made it one of the most recognizable firearms of the 20th century.

Adopted by the U.S. military during World War II, the Thompson 1921 saw service in various theaters, including Europe and the Pacific. It was particularly favored for close-quarters combat, where its stopping power and compact design gave soldiers a distinct advantage. The weapon was also supplied to Allied forces through Lend-Lease agreements.

Though eventually replaced by lighter and cheaper submachine guns like the M3 Grease Gun, the Thompson 1921 remains a cultural icon. Its association with the Roaring Twenties, gangster films, and World War II has cemented its place in popular culture and firearms history.
