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 unique variant of the .45 Auto pistol with a much shorter barrel, it features a custom skeletonized hammer and trigger; commander length slide and a snake-skin grip, along with the etched Greek text "καὶ τὸ φῶς ἐν τῇ σκοτίᾳ φαίνει (kaì tò phõs én tẽ skotía phaínei)" on the right side and "καὶ ἡ σκοτία αὐτὸ οὐ κατέλαβεν (kaì é skotía aútò oú katélaben)" on the left side, which translates as "And the light shineth in darkness and the darkness comprehended it not." It also has "trench" sights (a groove running along the top of the pistol 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 firearm. Compared to its standard counterpart, it has greater DPS, less spread, greater critical chance and damage, a greater rate of fire and greater durability, albeit having one less round in the magazine. Unlike the .45 Auto pistol, when aiming down the trench sights, the weapon zooms in more than a regular, un-scoped pistol, making longer range encounters much easier. 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.

Durability
A Light Shining in Darkness can fire a total of about 1,245 rounds, the equivalent of 208 reloads, from full condition before breaking.

Variants

 * .45 Auto pistol - The standard variant found throughout Zion Canyon, and purchasable from merchants in the Mojave Wasteland after the completion of Honest Hearts.
 * A Light Shining in Darkness (non-player character) - A unique playable variant used by Joshua Graham. It differs from the standard variant by having 50 base and crit damage, 2x 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 variant 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.

Location
It is carried by Joshua Graham and can be retrieved from his corpse if he is killed. Alternatively, it can be found in a footlocker at the southern passage in Zion Canyon after completion of the Honest Hearts main questline.

Behind the scenes

 * The design is loosely based on various Officer-sized compact Colt M1911s. It is not a complete copy, as it should have a reversed recoil plug. The Colt New Agent is the closest equivalent real-world production model.
 * The phrase engraved on the slide of the pistol is from the Bible passage John 1:5, "The light shines in the darkness, and the darkness has not overcome it."
 * The same phrase is used repeatedly in the Doctrine & Covenants, one of the Standard Works of the Mormon Church.

Bugs
If loading a saved game from the main menu in which you have A Light Shining in Darkness 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.
