The 9×19mm Parabellum is one of the most commonly used pistol cartridge in-game. It is mostly used by pistols and submachine guns. This caliber has weak penetration power but weapons using this caliber type usually have high rate of fire. It is the cheapest caliber in-game costing $20 per 30 rounds.


The weapons that are chambered with 9mm cartridge:




  • It can be stated that the counterpart for 9×19mm Parabellum is the .45 ACP.
  • Guns using this caliber usually have low firepower but also have low recoil and high rate of fire.
  • Note that submachine guns use pistol cartridges instead of rifle cartridges, so if a submachine gun and a pistol both use the same ammunition, the player will end up with the same ammunition pool.
  • The H2O and 9mm AHE ammunitions share the same properties as the 9×19mm Parabellum. The only difference is the HUD icon.
