The 9x19mm, also known as 9mm Parabellum or 9mm Luger, is a popular handgun cartridge widely used in military, law enforcement, and civilian firearms. It was developed in 1902 by Georg Luger and has become one of the most common pistol calibers in the world due to its balance of power, recoil, and magazine capacity. This cartridge measures 9mm in diameter and 19mm in case length. It is known for its versatility, being suitable for various applications, including self-defense, target shooting, and competitive shooting. Many firearms, such as the Glock 17 and Beretta 92, are chambered for the 9x19mm.
