STATUS – Obsolete

SERVICE – Designated “Substitute Standard” in April, 1942

     Designed by George Hyde, this was an evolution of his previous weapons. Submitted as the Hyde-Inland II in June, 1942. The design proved superior to the M1 and M1928A1 Thompsons in general accuracy, particularly in full automatic fire. Minor improvements to the basic design (deepening the magazine well and redo the buffer) resulted in the weapon being recommended for adoption. Many difficulties prevented the weapon from reaching production until May, 1943. That was five months after the M3 “Greasegun” had been standardized. The production of the M2 was ceased after about 400 weapons had been produced.
