9×25mm Mauser

The 9×25mm Mauser (or 9mm Mauser Export) is a cartridge developed for the Mauser C96 service pistol around 1904 by DWM. Mauser pistols in this relatively powerful caliber were primarily intended for export to Africa, Asia, and South America. The 9mm Mauser Export cartridge was produced specifically for Mauser pistols and carbines made from 1904 to 1914 and then later from approximately 1930 to 1945 for submachine guns chambered for this caliber.
