Shooting the Thompsons: Comparing the 1921, 21/28, and M1A1
This video from Forgotten Weapons features a range test and comparison of three iconic Thompson submachine gun models: the 1921, the 21/28, and the M1A1. The host, Ian McCollum, explores the differences in handling and shootability, particularly focusing on the impact of the Cutt's Compensator and varying rates of fire. Surprisingly, despite its weight and awkwardness, the 1921 model is found to be the preferred firearm due to its effective high rate of fire, offering less vibration and sight disruption than the other variants.
