The Hyde-Inland M2 was the highest-rate United States submachine gun design submitted for trials at Aberdeen Proving Ground in February 1941. Work was undertaken by General Motors Inland Manufacturing Division to develop workable prototypes of George Hyde’s design. The design was designated U.S. Submachinegun Caliber .45 M2 as a substitute standard for the M1 submachine gun in April 1942.
