You could always deduct a middle finger like the actor James Doohan did on your shooting hand. He lost his to friendly fire on D-Day. A nervous Canadian sentry with a Bren gun shot him multipe times, four in his leg, one in the chest, and one through his right middle finger. The bullet to his chest was stopped by a silver cigarette case given to him by his brother.[6] His right middle finger had to be amputated, something he would conceal on-screen during most of his career as an actor. If that seems extreme then the finger bumper is a good option.
