A Light Shining in Darkness

A Light Shining in Darkness is a unique weapon in the Fallout: New Vegas add-on Honest Hearts.

Characteristics
A shorter, unique variant of the .45 Auto pistol, it features a custom hammer, a three-holed trigger, and a snake-skin grip, along with the etched Greek text "καὶ τὸ φῶς ἐν τῇ σκοτίᾳ φαίνει" (Kai to phoos en tè skotia phainei) on the right side and "καὶ ἡ σκοτία αὐτὸ οὐ κατέλαβεν" (Kai hè skotia auto ou katelaben) on the left side, which translates as "And the light shineth in darkness and the darkness comprehended 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 added to 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 the player's sneak skill is 50 or greater.

A Light in Shining Darkness can be repaired by the .45 Auto pistol or any semi-automatic pistol with the Jury Rigging perk.

Variants

 * .45 Auto pistol, standard variant found through out Zion Canyon and purchasable from merchants in the Mojave Wasteland.
 * A Light Shining in Darkness (NPC), 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.
 * Joshua's Pistol Whippin' .45, 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 used by Follows-Chalk, a Dead Horses tribal and companion to the Courier. It only differs from the standard pistol in its use of companion ammunition and possession of the standard iron-sights.

Locations
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.

Behind the scenes

 * The design is loosely based on various Officer-sized compact Colt M1911s. It isn't, however, an accurate copy, as it should have a reversed recoil plug.
 * The phrase engraved on the slide of the pistol is almost completely similar to the Bible passage John 1:5. It is a metaphoric reference to Jesus Christ.
