The 30 Luger (7.65x21 Parabellum, 7.65 Luger) was developed by Georg Luger and Huge Borchardt in 1898. It is a bottle-necked case firing a 93-grain .309-inch (7.65mm) bullet at 1200 feet per second, very fast for its day. Luger's pistol in 30 Luger was adopted by the Swiss in 1900. 30 Luger was used as a military pistol cartridge by Germany and Finland as well as Switzerland, and it was chambered to numerous pistols. The 9mm Luger (9x19mm) cartridge is essentially the 30 Luger with the bottleneck removed, thus necked up to 9mm. With other case dimensions identical many 30 Luger pistols can be rebarreled to 9x19. Adoption of 9mm Luger by the German army in 1908 was essentially the death knell of the 30 Luger, but 30 Luger pistols remain in use and ammunition is readily available.
