[edit] History
The 9x18mm caliber was the standard pistol caliber for Eastern European countries, many of which still use this caliber today. 9x18mm caliber uses a larger diameter bullet than other 9mm rounds. 9mm Parabellum is 0.355 inches, however 9x18mm rounds are loaded with bullets measuring 0.363 inches. As a result, different bullets must be used to load 9x18mm cartridges.
As of the Summer of 2005, the Russian military and the Chinese military plan on replacing the 9x18mm cartridge with the 9mm Parabellum cartridge along with pistols of their own design.
[edit] Performance
9x18mm is ballistically slightly inferior to the 9mm Parabellum cartridge. This is due to the 9x18mm being a straight cartridge (.392 caliber rim to .390 neck) rather than the slightly tapered 9mm Parabellum (.394 to .380 neck).[citation needed]
The 9x18mm cartridge is not interchangeable with slightly less powerful .380 ACP, 9mm Parabellum, 9mm Largo or any other western cartridge.
