Trivia

 * It can be stated that the counterpart for 9x19mm 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 both the submachine gun and pistol bullets, having no extra ammunition after reloading.
 * The H2O and 9mm AHE ammunitions share the same properties as the 9x19mm Parabellum. The only difference is the HUD icon.
