Charon's Combat Shotgun (Fallout 3)

Charon's unique shotgun 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 magazine size (5 instead of 12). Generally speaking, Charon's shotgun outclasses any other shotguns. Its damage scales with Charon's level.

Despite the fact that its appearance is identical to the standard combat shotgun, Charon's shotgun is a pump action shotgun. If you give him a standard combat shotgun and ammo, he will not pump it. It also appears to eject rifle shells as opposed to shotgun shells.

It cannot be looted from his corpse.

Trick
There is a trick to make Charon reload without time delay. Simply talk to him when fighting, ask for trade(force reload) or just close the dialog(when he shoots about 5 times). This can save him from dangerous situations.

Using the console I was able to aquire the shotgun but it comes with 0 rounds and can't seem to be reloaded.
