Caliber 9x19 (9 mm Luger): energy, velocity and use
The caliber 9 x 19 (alternative names: 9 mm Luger, 9 mm Para, 9 mm Parabellum) is one of the most widespread calibers for semi-automatic pistols. The cartridge is also used in submachine guns and is the standard caliber for most authorities. The caliber 9 x 19 is the only NATO caliber developed in Germany.
The muzzle velocity ranges from 270 - 600 m/s, with a maximum gas pressure of about 2300 bar. Projectiles in 9 x 19 develop a bullet energy of about 370 - 750 joules. Hunting use is possible, but most hunters prefer small calibers like .22 lfB or large ones like .44 Magnum depending on the purpose.
