The 9 mm Winchester Magnum, which is also known as the 9x29mm, is a centerfire handgun cartridge developed by Winchester in the late 1970s. The cartridge was developed to duplicate the performance of the .357 S&W Magnum in an auto-pistol cartridge.
The first handgun which chambered the cartridge was the Wildey pistol. Since then, Thompson/Center has produced barrels chambered for this cartridge and AMT chambered their Automag III for it too, but the cartridge never reached the popularity enjoyed by other handgun cartridges and could now be considered obsolete.
