The 9 × 23 mm Winchester is the 9 × 23 mm Winchester is a rimless, straight taper, brass case, Boxer primed cartridge. It was derived from the 9 × 19 mm Parabellum cartridge by lengthening the case and increasing the powder load. It is very similar to the 9 mm Largo and 9 mm Steyr cartridges and can be distinguished from these by the fact that the 9 × 23 mm Winchester is loaded only with JHP or JSP, rather than FMJ bullets. The 9 × 23 Winchester cartridge was developed as a joint venture by Colt and

Winchester-Olin to provide a cartridge for semi-automatic pistols that would develop terminal ballistics on a par with those of the .357 Magnum. Compatible platforms include suitably chambered pistols.
