The 7.65mm Browning cartridge was introduced to the European market by the Belgium firm Fabrique Nationale in 1899 in John Browning's first successful semiautomatic pistol. In 1903, Colt introduced its first Browning designed autoloader, the Pocket Model, chambered for the same cartridge, but renamed it the .32 Automatic Colt Pistol, or .32 ACP for short. Of semirimmed design, the .32 ACP was introduced with a 71 grain full metal jacket bullet at a muzzle velocity of slightly over 900 fps for around 130 foot pounds of kinetic energy. Several U.S. Companies offer factory loads for this cartridge, but Winchester's loading with a 60 grain hollowpoint bullet at 970 fps is often preferred by the very few law enforcement personnel who continue to use this relatively anemic cartridge in pocket pistols for backup purposes. Winchester lists the muzzle energy of its factory load as 125 foot pounds. Even though many other cartridges enjoy far greater publicity, it is thought that more handguns have been chambered for the .32 ACP than for any other. It is estimated that during the first 10 years of the .32 ACP's existence, Fabrique Nationale alone produced over 500,000 pistols in this caliber.
