A unique shorter variant of the .45 Auto pistol, it features a custom hammer, a three holed trigger, and a snake-skin grip, along with an etched Greek text "καὶ τὸ φῶς ἐν τῇ σκοτίᾳ φαίνει" on the right side and "καὶ ἡ σκοτία αὐτὸ οὐ κατέλαβεν" on the left side of the slide, which translates as "And the light shineth in darkness and the darkness captured it not" . It also has "guttersnipe" sights (a groove which the player aims down), rather than having a rear notch and a front post.
Like most unique weapons, weapon modifications cannot be used on this weapon. Compared to its standard counterpart, the .45 Auto pistol, it has more damage per shot, less spread, a greater rate of fire, and greater durability, albeit having one less round in the magazine. As with the .45 Auto pistol, it is considered an improved holdout weapon, and can be concealed and taken into weapon-free locations so long as your sneak skill is 50 or greater.

- A Light Shining in Darkness (NPC), is a unique non-playable variant used by Joshua Graham. It differs from the standard variant by having 50 base and crit damage, 3x crit chance and a min spread of 0.35. It also uses the same Pip-boy icon as the 9mm pistol (Fallout: New Vegas).
- Joshua's Pistol Whippin' .45, is a unique non-playable variant used by Joshua Graham. It differs from the standard variant by being used as a melee weapon.
- Follows-Chalk's .45 Auto pistol, a unique version is used by Follows-Chalk, a Dead Horses tribal and a companion. It only differs from the standard pistol in its use of companion ammunition and has the standard iron-sights.
It is carried by Joshua Graham. It can be retrieved from his corpse if killed, alternatively, it can be found in a footlocker at the Southern passage in Zion Canyon after completion of the Honest Hearts main quest.
- When aiming down the weapon's iron sights, bullets tend to land quite a bit above the groove in the sights. It may be necessary at some ranges to compensate for this by positioning the groove slightly below where you intend to hit.
Behind the scenes
- The phrase engraved on the slide of the pistol is the Bible passage John 1:5. It is a metaphoric reference to Jesus Christ.
