The M1944 Hyde Carbine was an attempt by George Hyde to manufacture a light rifle for the US Armed Forces. The overall weapon was based on the Thompson Submachine Gun which Hyde himself designed many of his weapons on. Although an original .30 Carbine calibre platform was based on the M1921/27 variants, It worked well but due to the war effort was found expensive for mass production and its weight defied the concept of a Light Rifle.
