The .44 Auto Magnum Pistol (AMP) is a large-caliber, semi-automatic pistol cartridge developed in 1971 by Harry Sanford.[2] The primary use is in the Auto Mag Pistol.[3] The cartridge was also employed in the Wildey automatic pistol, including a few other custom pistols.[4] While factory loads are manufactured, cases can be made by cutting down and reaming out .308 Winchester or .30-06 Springfield brass,[5] with ballistic performance similar to the .44 Magnum revolver cartridge.[3]
The .44 AMP was discontinued in 1982 after eleven years before being brought back sometime later in 2017, continuing current production to the present time.
