John Hartigan (Bruce Willis) narrates his encounter with child rapist/killer Roark Jr.(Nick Stahl) on a dock in Sin City: "I take his weapons away from him. Both of them." This is the arm that the detective shoots off the villain in the film adapted from Frank Miller's graphic novel.

Prop and description from Prop Store of London:

"Roark Jr's (Nick Stahl) SFX severed gun holding hand used in the comic book style thriller Sin City. The prop hand is still holding onto a silver and black gun and was used in the scene when Hartigan (Bruce Willis) has Roark Jr. cornered on the pier and shoots his arm off as he lays on the ground. The hand and gun are made from hard rubber and have been painted with a realistic skin tone, it has nail detailing and prop blood at the end of the leather coat. Measures 45cm (17.75”) long."

The prop gun is based on a Colt compact. The entire prop is lifesize and the skin is very detailed. Cracking is evident around one of the fingernails, but nothing is missing (besides the rest of the creep's body).
