The Colt 6520 10mm pistol is a small gun in Fallout and Fallout 2.


It is a highly durable and efficient weapon developed by Colt Firearms prior to the Great War. It proved to be resistant to the desert-like conditions of the post-nuclear wasteland and is a fine example of workmanship and quality construction (at least for the pre-War models, which became more scarce over time). The simple design of the gun allows it to be easily manufactured with relatively basic equipment, making it possible to be replicated in workshops in the post-nuclear world. The Colt 6520's durability, reliability, and simple design make it very popular among wasteland denizens, for whom sophisticated high maintenance weapons would be a liability to survival.[1]



  • The 6520 is a standard-issue firearm for vaults. The Vault Dweller starts with one.
  • Sold in weapons shops in the Hub.
  • Ian uses one.
  • Carried by raiders.

  • Many slavers use them.
  • Carried by Iguana Eater.


The Colt 6520 10mm pistol appears in Fallout and Fallout 2. In Fallout 3 and Fallout: New Vegas, it was replaced by the N99 10mm pistol.
