The .32 S&W Long is a straight-walled, centerfire, rimmed handgun cartridge, based on the earlier .32 S&W cartridge. It was introduced in 1896 for Smith & Wesson's first-model Hand Ejector revolver. Colt called it the .32 Colt New Police in revolvers it made chambered for the cartridge.
The .32 S&W long was introduced in 1896 with the companies first hand ejector revolver. The .32 S&W long is simply a lengthened version of the earlier .32 S&W cartridge. The hand ejector design has evolved some, but with its swing out cylinder on a crane, has been the basis for every S&W revolver designed since. In 1896 the cartridge was loaded with black powder. In 1903 the small hand ejector was updated with a new design, the cartridge stayed the same, but was now loaded with smokeless powder to roughly the same chamber pressure.
When he was the New York City Police Commissioner, Theodore Roosevelt standardized the department's use of the Colt New Police revolver. The cartridge was then adopted by several other northeastern U.S. police departments. The .32 Long is well known as an unusually accurate cartridge. This reputation led Police Commissioner Roosevelt to select it as an expedient way to increase officers' accuracy with their revolvers in New York City. The Colt company referred to the .32 S&W long cartridge as the .32 "Colt's New Police" cartridge, concurrent with the introduction of the Colt's Police Positive revolver. The cartridges are functionally identical with the exception that the .32 NP cartridge has been historically loaded with a flat nosed bullet as opposed to the round nose of the .32 S&W long.
In the United States, it is usually older revolvers which are chambered in this caliber. The cartidge has mostly fallen out of use due to smaller revolvers chambered in .38 S&W Special being more effective for self-defense.
The .32 S&W Long is popular among international competitors using high-end target pistols from makers such as Hämmerli, Benelli, and Walther, among others, but chambered for wadcutter bullet type. The sporting variant of the Manurhin MR 73 is also chambered in .32 S&W Long.
The .32 S&W Long headspaces on the rim and shares the rim dimensions and case and bullet diameters of the shorter .32 S&W cartridge and the longer .32 H&R Magnum and .327 Federal Magnum cartridges. The shorter .32 S&W cartridges may be fired in handguns chambered for the .32 S&W Long; and the .32 S&W Long cartridges may be fired in arms chambered for the longer .32 H&R Magnum cartridge; although the longer cartridges should not fit and must not be fired in arms designed for the shorter and less powerful cartridges.
The .32 S&W long and .32 Long Colt are not interchangeable as the .32 S&W Long and .32 Colt New Police cartridges are, neither is the .34/44 cartridge. At one time it was widely publicized that these rounds would interchange, but it is no longer deemed safe to do so.
