The 5.56mm pistol is a weapon added with the Fallout: New Vegas add-on Gun Runners' Arsenal.


This section is transcluded from .223 pistol. To change it, please edit the transcluded page.

The original .223 pistol that became one of the iconic weapons of New California, was originally a full sized .223 revolving rifle, belonging to Irwin, a farmer outside of the Hub. He cut his rifle down to the size of a large pistol, but leaving the vestigial trigger intact.[1] This unique weapon offered firepower comparable to a hunting rifle in the compact package of a pistol. Five rounds of .223 ammunition were more than enough to deal with most dangers out in the wastes.[2]

This iconic sidearm caught the eye of gunsmiths the following years, and the pistol saw mass production but modified to fully accommodate the more powerful 5.56mm.[3][Non-game 1] Vestigial elements like as the double triggers were shed to improve performance. The internal mechanisms are retained from the original .223 revolving rifle, modified as needed to create a powerful double-action revolver.[4]


5.56 pistol expanded

A 5.56mm pistol, it looks clean with an intact black finish. It has two small red LEDs on the side, and a large pale green LED on the back. Much like its unique variant That Gun, it is a heavily modified, pared-down .223 pistol, successor to the same weapon from Fallout and Fallout 2. It weighs five pounds and has a motorized cylinder and crane for quicker shooting and reloading. When reloading, the cylinder mechanically swings open to the left and auto-ejects the spent casings for a more efficient reload time. The green light on the left side turns yellow while reloading, then turns green and emits a ringing noise once the weapon has reloaded. The two variants of this weapon share the capability to use dedicated armor piercing rounds, a trait that is unique among pistols.

Unlike That Gun, the 5.56mm pistol is considered an improved holdout weapon, and thus can be concealed with a Sneak skill of 50 or higher. Along with its unique variant, it is the only pistol in the game that loads armor piercing ammunition that does not require the Hand Loader perk to fabricate.


The 5.56mm pistol can fire a total of about 870 standard rounds, or 174 reloads, from full condition before breaking.

Behind the scenes

Like That Gun, this pistol is modeled on the pistol used by Rick Deckard, the main character of the film Blade Runner, but is not an exact copy. That Gun and the 5.56mm pistol being used to destroy 15 robots with Benefit Or a Hazard challenge is a specific nod.

  1. IrishHooman: "Why was it called "That Gun" anyway? always wondered"
    Joshua Sawyer: "because it's That Gun From Fallout/Fallout 2/Blade Runner. also we didn't have .223 as a primary ammo type."
