Charon's combat shotgun

Fallout 3
Charon's unique Combat Shotgun which does not deteriorate, has infinite ammo, and has its unique firing spread and firing rate. It will fire perfectly straight with a very tight spread that hardly gets wider. It cannot be interacted with.

Compared to standard combat shotgun, Charon's shotgun has MUCH higher accuracy and longer range with smaller clip size (5 instead of 12). Generally speaking, Charon's shotgun outclasses any other shotguns.
