My son had that same surgery twice, high school football injuries. With several months of therapy he was able to do almost anything he wants. He has to be careful with some activities, but shooting is no problem. Even fairly heavy recoiling guns aren't a problem.
You may have to give up martial arts. My son messed his up tackling a running back playing defensive tackle. After the 1st surgery he was told he could only play offense since it did not put the same strain on the shoulder. He was moved to Center and dislocated his pretty bad making a tackle after an interception. My sons shoulder would simply fall out walking down the hall as he changed classes. He got pretty good at putting it back in. He has no problems after the 2nd surgery, but was told to forget college ball.
