I'd vote for a device to allow a person with a physical impairment to the hand to fire it. I've seen a couple that were made up that allowed the shooter to fire a revolver with the thumb of the right hand pressing down on a lever on the left side of the frame. Acting through a pivot and counter lever it pulled the trigger. The ones I saw worked in SA mode only and looked to be custom built projects.
Plug the holes in the frame, reblue and keep shooting that one.
