The AMT Automag V 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. Production quantity was to be 3000 units, numbered 0001-3000 to 3000-3000. This goal was never reached. The MK V used the same frame as the MK IV, and pistols have been discovered with MK V frames with MK IV slides and vice versa.
