9×19mm Parabellum (Luger) Overview

The 9×19mm Parabellum, also known as 9mm Luger or simply 9mm, is the most widely used handgun cartridge in the world. Originally designed by Georg Luger in 1901 and adopted by the German military in 1908, it has become a global standard for both military and civilian use.

It is chambered in most modern pistols, submachine guns, and compact carbines.
