7.65x17SR, 7.65mm Browning, .32 ACP

The .32 ACP cartridge, as it is known in the USA and in Europe as 7.65mm Browning, is also designated as 7.65×17mmSR Browning. It was developed by John Browning in around 1896-97. This was in concert with one of his pistol designs – a simple blowback pistol, which he sold to the Belgian FN company in 1899.

In a very short time, the FN / Browning pistol of 1899/1900 pattern became very popular with European police and security forces. Just three years later this cartridge was introduced in the USA along with the Colt Model 1903 pistol, another creation of John Browning.

It must be noted that this cartridge never really caught on in the USA, and the only military use it saw there was in Colt’s Model 1903 pistols, issued to general officers of the US Armed forces until the mid-70’s. On the other hand, it found wide military acceptance in Europe, being issued to military personnel such as naval officers and aviators, and even to infantry officers in countries such as France, Germany, Hungary, and others. In the police ranks, this cartridge served well into the 70’s, being issued along with smaller pocket-type pistols, of which the most notable were the famous Walthers – PP and PPK.

This cartridge uses a brass cylindrical case with an extractor groove and a small rim (the so called semi-rimmed design, hence the SR suffix in the metric designation). The presence of a rim means that this cartridge was intended for use in both semi-automatic pistols and revolvers (a great many such weapons being made in Europe before World War One, mostly in Belgium). The standard loading is a jacketed bullet. However, nowadays several good factory loadings with expanding bullets are available in this caliber.
