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 drew inspiration from in many of his weapon designs. An original .30 Carbine based on the M1921/27 variants, it worked well but due to the war, effort was expensive for mass production and its weight defied the concept of a 'Light Rifle'.
