D,
Had my right shoulder totally replaced almost exactly two years ago. Doctor described it as a mess post surgery. It is a standard shoulder not reverse, he had both on hand if needed. Surgery was at 0700 and I was home that afternoon. Had me out of the sling the next day saying movement nose to toes with nothing behind the back. Long story short I was shooting trap eight weeks later. He said if it hurts don't do it. Now I don't even think about the shoulder, hasn't hindered anything I do. Heaviest recoil I deal with is a 35 Whelen and is no problem. Good luck. Dale
