The 9×20 mm Browning Long is a military centerfire pistol cartridge developed in 1903 for the 9 mm Browning pistol adopted by Belgium, France, the Netherlands, and Sweden. The cartridge headspaces on the rim. 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.
