Kellogg's pistol

Kellogg's pistol is a unique .44 pistol found in Fallout 4.

Background
Deeming her husband unable to provide for the family, Mrs. Kellogg entrusted her only son Conrad with a revolver, telling the little boy that the newly-formed New California Republic and what he learned in school was not to be trusted. This meant the only thing in the world that would protect him was the very weapon he held in his hands. Kellogg eventually became very adept with his revolver and became an expert marksman. He used the gun to kill countless opponents over the course of his extended life, including the Sole Survivor's spouse.

Gameplay
This .44 Magnum revolver is Kellogg's primary weapon of choice. The weapon originally had factory wooden grips and a standard barrel, but its owner eventually modified it with a bull barrel and synthetic comfort grips.

Kellogg's pistol has the Relentless effect which allows critical strikes to refill Action Points.

Weapon modifications
Kellogg's pistol comes with a standard receiver, bull barrel, comfort grip, and standard sights.

Variants

 * .44 pistol: Standard version.
 * Eddie's Peace: Unique scoped version that deals extra limb damage.
 * The Gainer: Unique .44 pistol with fire damage.
 * Early Retirement - Unique .44 pistol that deals extra damage against synths.

Location
Found on Kellogg after killing him (or near his body) in Fort Hagen, during the quest Reunions.

Behind the scenes
When Kellogg fires his gun in front of the player for the first time, the player can hear a spent casing hit the ground, even though revolvers do not eject spent casings. However, according to the firing sound's location in the game's files as well as its filename (Sound/FX/WPN/Pistol10mm/NPC/WPN_Pistol10mm_Fire_NPCKelloggChargen_01.wav), it seems that at some point in development, Kellogg was supposed to be using a 10mm pistol instead of his current .44 magnum.
