This type of .45 Automatic pistol was designed by one of my tribe almost four hundred years ago. Learning its use is a New Canaanite rite of passage.Joshua Graham

The .45 Auto pistol is a weapon in the Fallout: New Vegas add-on, Honest Hearts.


The .45 Auto pistol is a single-action, semi-automatic, magazine-fed handgun that utilizes .45 Auto ammunition. While the .45 AP improved sights modification was cut from the game, the sights are still present on the weapon's default model (pre- and post-modified versions). This gives the .45 Auto pistol luminescent sights, and as such, it is very effective in caves and dark areas.

Furthermore, it is considered an improved holdout weapon and can be taken into weapon-free locations with a Sneak skill of 50 or greater. It also has the highest base damage of any silenced holdout weapon once the AP silencer mod has been added.


The .45 Auto pistol can fire a total of about 745 standard rounds, the equivalent of 107 reloads, from full condition before breaking. When modded with the heavy duty slide, it can fire a total of about 1,120 standard rounds, the equivalent of 160 reloads, from full condition before breaking.

  • .45 Auto pistol improved sights – it appears as though there may have been an "upgraded iron-sight" mod available for this weapon but it was cut from the final release, and the weapon's default model uses them instead.

  • It can be purchased from the Gun Runners, Great Khans, Chet from Goodsprings, etc. after returning to the Mojave Wasteland. (The Gun Runners will have a 98% condition gun every three in-game days, also Gun Runners will restock attachments for .45 Auto pistol every three in-game days.)
  • It can be purchased from Joshua Graham. Two or three of them will reappear in his inventory after he arrives at the Sorrows' camp.
  • Although Graham is seen inspecting countless amounts of these pistols when talking with the Courier for the first time, only four in poor condition can be stolen from Joshua Graham's desk in Angel cave.
  • Some of these are used by tribals in Zion.
  • There is one in good condition in a footlocker behind Joshua Graham in Angel Cave.
  • One is given as a reward in perfect condition by completing the quest Bighorners of the Eastern Virgin.


According to Joshua Graham, it is based on a nearly 400-year-old design from one of his Mormon ancestors and is the trademark weapon of the New Canaanite tribe.

Behind the scenesEdit

  • The .45 Auto pistol is based on the Colt M1911, although it is not an exact replica.[1]
  • John Browning, the real-life inventor of the Colt M1911 on which the .45 Auto Pistol is based, was in fact a member of the Mormon Church and was born in Ogden, Utah.
