An improved Hyde-Inland 2 was designated U.S. Submachine gun, Caliber .45, M2 as a substitute standard for the M1 Thompson in April 1942. As Inland's manufacturing capacity became focused on M1 carbine production, the US Army contracted M2 production to Marlin Firearms in July 1942. Marlin began production in May 1943.
Notable differences of the T29 to the M3 SMG was the increased length of the magazine well and magazine release catch to use M1 Carbine magazines.
