The 9mm Winchester Magnum, which is also known as the 9×29mm, 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. [2] The first handgun which chambered the cartridge was the Wildey pistol.
Announced to the public in early 1996 at an NRA convention, the 9×23mm Winchester cartridge was claimed to have the lowest recoiling load and still qualify for Major Power Factor designation in the IPSC.

Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
While external dimensions are almost identical, the 9×23mm Largo is a very different cartridge from the modern, high-performance 9×23mm Winchester. Firing the thicker-walled 9×23mm Winchester round in a 9×23mm Largo pistol is dangerous, as old 9mm Largo pistols cannot handle the pressure generated by the 9×23mm Winchester. [citation needed]
The Wildey employs a unique short-stroke gas operation which allows the pistol to be adapted to fire several high-pressure cartridges ranging from the 9mm Winchester Magnum to the .475 Wildey Magnum. Moore described the Wildey patented gas system as an "air-hydraulic piston powered by the firing gases through six small holes in the barrel.
