The .38 S&W, also commonly known as .38 S&W Short (referred to as such to differentiate it from .38 Long Colt and .38 Special), 9×20mmR, .38 Colt NP (New Police), or .38/200, is a revolver cartridge developed by Smith & Wesson in 1877. Versions of the cartridge were the standard revolver cartridges of the British military from 1922 to 1963. Though similar in name, it is not interchangeable with the later .38 Special due to a different case shape and slightly larger bullet diameter.[1]
