10.9mm (.44 caliber) Auto Mag Pistol (AMP) cartridge

by Tim Wing

3The 10.9mm (.44 caliber) Auto Mag Pistol (AMP) cartridge was introduced in 1971. Its rimless, straight wall case was originally formed by trimming the .308 Winchester or .30-06 case to 1.30 inches (33 mm). This round was originally designed for the .44 Auto Mag pistol, a large caliber semi-automatic pistol designed between 1966 and 1971 by the Auto Mag Corporation. This round fell out of use in the late eighties but was resurrected with the introduction of the Monument Arms M-39 “Mesa Eagle” 10.9mm Magnum Gas-Operated Pistol. This pistol, along with the RRG – Monument M-42 .50CAP (Ceramic Automatic Pistol), was introduced in the early to mid-twenties as an answer to the ceramic tactical body armor then being introduced by adversary nations such as the Eastern Bloc of Soviet Independent States. The large size of this bullet made it possible to create a miniaturized High Explosive Anti-Personal Armor (HEAPA) bullet capable of piercing up to three inches steal plate. This, in addition to Tungsten-core Armor Piercing Sub-munition (TAPS), ball and hollow point ammunition made this a powerful and versatile round.
