A Light Shining in Darkness

A Light Shining in Darkness is a unique weapon $$

Gameplay
A unique variant of the .45 Auto Pistol with a shortened barrel, it features etched text "καὶ τὸ φῶς ἐν τῇ σκοτίᾳ φαίνει" on the right side and "καὶ ἡ σκοτία αὐτὸ οὐ κατέλαβεν" on the left side.

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 character'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.

Behind the scenes

 * Joshua Sawyer stated that the weapon is "loosely based on various 'Officer'-sized compact M1911s, though a compact M1911 like that should probably have a reversed recoil plug." He also stated, "The Colt New Agent is the closest equivalent" and that "One detail we did not reproduce in-game is the reversed recoil plug (found on many, if not all, Officer-length M1911s)."
 * The phrases engraved on the slide of the pistol are Greek and translate as "and the light shines in the darkness" followed by "and the darkness did not grasp it." They refer to John 1:5 in the Bible.
