.32 S&W cartridge (1878-Present, Union Metallic Cartridge Co.)
Smith & Wesson K32 Masterpiece Double Action Revolver
.32 S&W Long (1896—Present, S&W)
Smith & Wesson 32 Regulation Police
.32 ACP (1899-Present, John Browning)
The .32 S&W Long cartridge is derived from the .32 S&W, by increasing the overall brass case length, to hold more powder. Since the .32 S&W headspaces on the rim and shares the rim dimensions and case and bullet diameters of the longer .32 S&W Long, .32 S&W cartridges may be fired in arms chambered for these longer cartridges.
.32 ACP and .32 S&W are not the same cartridge and are not interchangeable. The .32 ACP (AKA 7.65 Browning) is a semi-rimmed cartridge for autoloading pistols, .32 S&W is a rimmed revolver cartridge.
Help me by adding other S&W firearms that fire these three cartridges.
