John Thompson's original prototype 1919 SubMachine "Tommy" Gun
This review delves into John Thompson's original 1919 prototype submachine gun, the precursor to the iconic 'Tommy Gun'. The prototype, brought to Colt in 1919, featured a .45 ACP caliber, an 'X' serial number, and lacked a stock or sights, serving as the 'pattern gun'. It evolved into the Model 1921, which incorporated a high-polish finish, finned barrel, compensator, stock, and drum magazine compatibility. Early production models were expensive and primarily used by gangsters and law enforcement.
