10mm submachine gun (Fallout 3)

FO76 publicteam xpd.pngFor an overview of the topic, see Submachine gun.

The 10mm submachine gun (SMG) is a small gun in Fallout 3.


With a fully automatic rate of fire and a 30-round magazine, the SMG is effective against wildlife and unarmored humans. 10mm ammo for the weapon is one of the most plentiful in the game. It is not accurate due a high spread. The 10mm SMG can fire a total of about 1190 times, the equivalent of 40 reloads, from full condition before breaking.


  • Sydney's 10mm "Ultra" SMG - Relic hunter Sydney's weapon of choice, the Ultra SMG holds an astounding 50 10mm rounds in a single magazine, and deals more damage than the standard SMG.
  • Operation: Anchorage Sim version - A sim-only version of the weapon which differs only in health, with a whopping 999,250 hit points, which essentially prevents the gun from ever degrading, well over 1500 rounds of ammunition can be fired without it degrading 1%. It can be obtained in the sim through certain equipment packs on the equipment terminal.
  • Cut Content 10mm Alloy Steel Submachinegun - Another version of the weapon was cut from the Operation: Anchorage add-on. Called the 10mm Alloy Steel Submachinegun, it is otherwise identical to the standard 10mm SMG.
