AMT AutoMag V

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, who also invented the original .44 AutoMag pistol. One of the extremely small number of handguns that fire a .50 caliber cartridge, it is also one of the few semi automatic guns that fires the .50 Action Express cartridge, it is said to be "the most ergonomic and lightweight of all of those autoloaders". Its built-in compensator ports in the barrel assist in keeping muzzle rise to tolerable levels. The recoil, however, is still surprisingly brisk even for the most experienced shooter. The Automag V has a 5-shot magazine capacity (5+1 total) and is, like all of the AMT pistols, made primarily of cast stainless steel.

Production quantity was supposed to be 3000 units, numbered 0001-3000 to 3000-3000. This goal was never reached, however. 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.
