The Guncrafter Industries Model No. 1 (Or M1) is a variant of the widely popular M1911 handgun, modified for the .50 GI cartridge. John Browning's 1911 .45 ACP has been used for many cartridges over the past century. In every instance the cartridge used a bullet with a diameter that was the same or smaller than the original .451". Both the Desert Eagle and the LAR Grizzly have been offered in cartridges of .50 caliber. Both are large cartridges requiring a large, heavy pistol.
