“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 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 is very effective in caves and dark areas.
Furthermore, it is considered an improved holdout weapon, and can be concealed and taken into weapon-free locations so long as your Sneakskill is 50 or greater. It is also the strongest silenced hold-out weapon that can be brought into weapon-free locations once the AP silencer mod has been added.
Durability
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 1120 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.
Joshua's Pistol Whippin' .45, is a unique non-playable variant used by Joshua Graham. It differs from A Light Shining in Darkness by being used as a melee weapon.
Four can be stolen from Joshua Graham's desk in Angel Cave. It is easiest to do this undetected by using the grab key to bring in to an unoccupied area, then taking it.
Some of these are used by tribals in Zion.
There is one of good condition in a footlocker behind Joshua Graham in Angel Cave.
They are sometimes found on the bodies of White Legs, though they are not seen using them while alive.
Notes
According to Joshua Graham, it is based on a nearly 400-year-old design and is the trademark weapon of the New Canaanite tribe.
John Browning, the real-life inventor of the Colt 1911 which the .45 Auto Pistol is based off of, was in fact a member of the Church of Jesus Christ of Latter-Day Saints and was born in Ogden, Utah.

Bugs
Xbox 360 Sometimes, when both modifications are attached to the .45 Auto pistol, it will not show in first person view while in the Mojave Wasteland.
Playstation 3 If both mods are attached and you use a weapon repair kit on it, the weapon stops degrading from use and can continue to be repaired past 100% increasing it's value and condition.
PC If loading a saved game from the main menu in which you have the .45 Auto pistol equipped and drawn, the reload animation takes twice as long as normal. This can be solved by simply switching to another gun and then back again.
PC Sometimes when aiming down the sight while in first person view, the gun will disappear entirely, switching to another weapon then back seems to fix the issue
