Introduced in 1896, the 32 Smith & Wesson Long round is a centerfire, straight-walled, rimmed handgun cartridge. Developed for Smith & Wesson’s first-model Hand Ejector revolver, the .32 S&W Long was based on the earlier .32 S&W cartridge. The .32 S&W Long round is also called the .32 Colt New Police by Colt.
