Whether you call it the 9mm Luger, 9mm Parabellum, 9mm NATO, 9 millimeter, or just plain 9mm, 9x19mm ammunition is the most popular cartridge for handguns in the world – with more than 60% of the world’s law enforcement agencies currently using this ammo. The role of 9mm Luger bullets in World War I and its continued popularity today testifies to its capabilities as an efficient and effective cartridge.
