First off tell your dad to get better!

If this isnt going to be a permenant injury you might want to encourage him to give the lefty idea a try rather than buy an entirely new gun. I dislocated my shoulder two yrs ago and the doc said not to shoot with it so I just practiced a little and it worked out. You just have to remind him to close his right, dominant, eye and shoot with his left if he wants to hit something.[:-]
