Thompson M1A1 submachine gun

The Thompson M1A1 is a modification of the famous American Thompson submachine gun, developed by John T. Thompson during the First World War. This modification, which dates back to 1943, brought several modifications compared to the original model.

In 1942, it was necessary to simplify the construction in order to save important materials and make production more efficient. The result was the Thompson M1 with a dynamic bolt, and later the Thompson M1A1 with a fixed bolt. The visible difference is the bolt cocking lever - on the first model at the top, on the others on the right side of the weapon. Another change was the replacement of the adjustable sight with a fixed dioptric sight.

However, due to production costs and technological simplification, production of the Thompson M1A1 ended in 1943. It was replaced by the newer and simpler M3 Grease Gun submachine gun.

The Thompson M1A1 gained popularity during the Prohibition era in the US, when it was widely used by both the US police and the underworld. Its distinctive design, reliability and ability to fire quickly earned it the nicknames Tommy Gun or Chopper. It was a symbol of the time and known especially for its use in film and literature. The Thompson remains an icon of American guns and still maintains its place in the world of shooting enthusiasts and collectors. Its robust construction and historical significance make it an exceptional and rare piece in the world of firearms.
