The .38 Special, also commonly known as .38 S&W Special (not to be confused with .38 S&W), .38 Smith & Wesson Special, .38 Spl, .38 Spc (pronounced "thirty-eight special"), or 9×29mmR is a rimmed, centerfire cartridge designed by Smith & Wesson.
The .38 Special was the standard service cartridge for the majority of United States police departments from the 1920s to the 1990s. It was also a common sidearm cartridge used by United States military personnel in World War I, World War II, the Korean War, and the Vietnam War. In other parts of the world, it is known by its metric designation of 9×29.5mmR[6] or 9.1×29mmR.[7]
Known for its accuracy and manageable recoil, the .38 Special remains one of the most popular revolver cartridges in the world[8] more than a century after its introduction. It is used for recreational target shooting, formal target competition, personal defense, and small-game hunting.
