Charles J. Guiteau’s Revolver

Origin
Charles J. Guiteau was a frustrated office-seeker who shot and killed 20th American president James A. Garfield. Guiteau practiced for a month on his revolver, getting used to the kickback. He chose ivory grips, which he thought would look better in a museum display, which it did until the Smithsonian “lost” it. Garfield was shot twice in the back and most likely died not from the bullet wounds, but from infection due to unsterilized surgical instruments. He died two months later and Guiteau was tried as insane and sentenced to hang.

Effects
The gun fires off bacterial diseases instead of bullets. It will cause whoever is shot to develop an infection that quickly spreads throughout the entire body. The effects can cause debilitating pain in the victim and firer, mostly around the back for the victim and the neck for the shooter.
