what's the difference between 9mm luger and parabellum
9×19mm Parabellum The 9×19mm Parabellum is a firearms cartridge that was designed by Georg Luger and introduced in 1902 by the German weapons manufacturer Deutsche Waffen und Munitionsfabriken (DWM) (German Weapons and Munitions Factory) for their Luger semi-automatic pistol.[5] For this reason, it is designated as the 9mm Luger by the SAAMI,[6] and the 9 mm Luger by the C.I.P..[3]
