9x21 med mer

The 9x21 mm (also called 9x21 mm IMI) pistol cartridge was designed by Israel Military Industries. Based on the 9 mm Luger cartridge, the casing was lengthened from 19 mm to 21 mm. The bullet sits slightly deeper, which results in the same overall length as the 9 mm Luger cartridge. As it is a rimless round, the 9x21 is used in USPSA/IPSC competition in Open class firearms. The reasoning is that the semi-rimmed case will not lock together in a double-column magazine, causing a malfunction, whereas an improperly built .38 Super firearm can, as the rimmed cases can lock together in the magazine, causing a jam. As other .38 Super based rimless cases became available, the 9x21 decreased in popularity in the US for competition use, but it is still widely used in the rest of the world. These competition rounds are handloaded and not available commercially.
