9mm Browning Long is similar to the 9×19mm Parabellum, but has a slightly longer casing and is semi-rimmed, so the cartridge headspaces on the rim. 9×19mm also uses a heavier bullet and is more powerful. Ammunition was produced in Belgium, France, England, Sweden and the United States. There was some production in Germany during World War I for the Ottoman Empire, and the cartridge was also used in South Africa.
The cartridge is now obsolete and it is hard to find reloadable brass for this ammunition; one option handloaders have is to take the .38 Super and shorten it to the right length.
As of 2016-04 Prvi Partizan in Serbia still manufactures 9mm Browning Long ammunition.

CIP barrel dimensions are 0.351" for minimum bore diameter, and 0.359" for minimum groove diameter.
