9×19mm Parabellum is an ammunition type in Fallout, Fallout 2, Fallout: New Vegas, Fallout Tactics, Fallout: Brotherhood of Steel and was planned to appear in Van Buren.


175 years old by the time the Great War happened, the 9×19mm Parabellum was one of the most popular and widespread ammunition types in the world. Although the U.S. military and federal agencies transitioned to the more powerful 10mm Auto cartridge, the venerable Parabellum remained popular throughout the United States of America. After the war, following a period of scarcity, it re-emerged as the primary pistol round of the New California Republic Army, used by the standard M&A 9mm pistols issued to its troops.


9mm, full metal jacket (ball)


The standard 9x19mm Parabellum round features a design that has seen little change since 1902. It boasts good accuracy, flat trajectory, moderate recoil, and good wound ballistics. In short, it is a reliable ammunition type that will do everyone proud.

9mm, jacketed hollow point


A hollow point 9x19mm specialty round, where the hard metal jacket is applied specifically to increase bullet strength and create a middle ground between damage potential and penetration.

9mm, armor piercing

Gameplay articles:

A variant of the 9x19mm round, designed specifically to defeat enemy body armor. The softer metal jacket covers a dense penetrator, while the bullet is loaded with a higher powder load, leading to improved muzzle velocity. However, improved performance against armored targets leads to impaired performance against softer targets, as the higher velocity reduces the amount of kinetic energy transferred to the target on impact.

9mm, overpressure (+P)

Gameplay article:

A specialty round developed in an attempt to improve the ballistics of the cartridge. The high pressure loading boosts ballistic performance, resulting in better wounding capacity. However, the same load also puts stress on the weapon, increasing the rate at which it wears out.

9mm, hollow point

Gameplay articles:

Hollow point bullets feature a hollowed out shape at the tip of the bullet, causing the bullet to expand upon impact, delivering more kinetic energy to the target and disrupting tissue more extensively. However, this same property also leads to reduced penetrative power, as the bullet will be stopped by armor much more easily due to its properties.

They were also referred to as DD or dum-dum bullets in Van Buren.
