.32 S&W Long

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.

History
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 it's 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.

Current Use
In the United States, it is usually older revolvers which have this caliber.

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 IOF .32 Revolver manufactured by the Ordnance Factories Organization in India for civilian licence holders is chambered for this cartridge.

Interchangability
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 arms 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 shorter cartridges.

The .32 S&W long and .32 Long Colt are not interchangeable. The .32 S&W long and .32 Colt's New Police cartridges are.
