Joseph Smith's Pepperbox Pistol

Joseph Smith's Pepperbox Pistol is an 'ancient artifact' of the Jesus Christ Church of Latterday Saints, which has been decommissioned and recommissioned since the death of Joseph Smith in 1844. In New Canaan, the gun has been passed down from Mormon leader to Mormon leader, since it was found in the late 2100s.

Background
This was the side arm of Joseph Smith, the founder of the Mormon church, that he had on his person the day that he was killed. He actually shot three men with it before going down.

The gun was put on display as a historical artifact for centuries after his death and was decomissioned during this time. However, after the bombs dropped, the gun, along with the other artifacts were buried under rubble.

The Mormon church eventually found the gun and had their best gunsmiths get it to working condition, replacing as few parts as possible. The gun is very old and even in its hayday, it wasn't the most efficient or effective weapon but that hardly matters to the one who holds it as it has a symbolic value, that is worth a lot more.

It is currently carried by Jeremiah Rigdon, the leader of the Mormon Church. He has never fired it before and probably never will as it's basically ceremonial.
