The .45 Auto pistol is a single-action, semi-automatic, magazine-fed handgun that utilizes .45 Autoammunition. 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 Sneakskill of 50 or greater. It is also the strongest silenced holdout weapon that can be brought into weapon-free locations 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.
They are sometimes found on the bodies of White Legs, though they are not seen using them while alive.
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 scenes
The .45 Auto pistol is based on the Colt M1911, although it is not an exact replica.
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.
