The AMT Automag IV is a large single action semi-automatic pistol made by Arcadia Machine and Tool (AMT). The weapon was created by Harry Sanford, inventor of the original .44 AutoMag pistol. This model fires the .45 Winchester Magnum round; however until 1993 it was chambered for a time in the obscure 10mm Magnum cartridge. It has a 7- or 8-round magazine and is made of stainless steel.
