The Thompson submachine gun, affectionately known as the "Tommy Gun," has been an iconic firearm for nearly a century. Its popularity has endured through various iterations, and its legendary status has been cemented in popular culture. The Thompson SMG semi-automatic is a modern twist on the classic design, offering a unique shooting experience for firearms enthusiasts. In this article, we will delve into the history of the Thompson submachine gun, its evolution, and the features of the modern semi-automatic variant.
History of the Thompson Submachine Gun

The Thompson submachine gun was first conceived in the early 20th century by John T. Thompson, a U.S. Army ordnance officer. Thompson aimed to create a handheld, fully automatic firearm that could be used by troops in trench warfare during World War I. The first prototype, known as the "Annihilator I," was developed in 1917. However, the war ended before the gun could see combat.
In the 1920s, Thompson continued to refine his design, and the first production model, the M1921, was released in 1921. The Thompson submachine gun quickly gained popularity among law enforcement and civilians due to its compact size, reliability, and high rate of fire. Unfortunately, its popularity also extended to the criminal underworld, with notorious gangsters like Al Capone and John Dillinger often using the Thompson SMG in their nefarious activities.
Military and Law Enforcement Use
During World War II, the Thompson submachine gun saw extensive use by Allied forces, particularly in urban and close-quarters combat situations. Its compact size and high rate of fire made it an ideal choice for soldiers in these environments. The Thompson SMG also saw service in the Korean and Vietnam Wars, although it was eventually phased out in favor of more modern designs.
Law enforcement agencies also adopted the Thompson submachine gun, and it remained a staple in many police departments until the 1970s. However, the high cost of production and the development of more modern, lighter, and more efficient designs led to the decline of the Thompson SMG's popularity.
The Modern Semi-Automatic Variant

In recent years, firearms manufacturers have released semi-automatic variants of the Thompson submachine gun. These modern designs retain the classic look and feel of the original while complying with contemporary firearms regulations.
The Thompson SMG semi-automatic is typically chambered in.45 ACP and features a blowback-operated, closed-bolt design. This allows for reliable and consistent performance, with a rate of fire comparable to the original fully automatic version.
One of the most notable features of the modern semi-automatic Thompson SMG is its ability to accept detachable magazines. This allows users to quickly reload and continue firing, making the gun more practical for self-defense and recreational shooting.
