M1928 Thompson Submachinegun

Description

This is the gun that made the 1920s roar, and came to symbolize the American gangster of the era. It was used in practically all American gangster movies and came to be nicknamed the Tommy gun.

The weapon was originally adopted (as the M1921) by the U.S. Postal Service, and a year later by the U.S. Marine Corps.

Note: The maximum calculated barrel length for this ammunition is 23 cm. To achieve the historical overall length of this weapon, the barrel was increased to 42 cm. However, all calculations for muzzle energy, damage, range and recoil were generated using the 23 cm value.
