RMC,
I have no answer for you. I'm looking for the same answer myself.

I had rotator cuff surgery on December 31, 2007, so today I am 14 weeks post-surgery. (The photo was 10 days post-surgery.) I have recovered most of my range of motion, but not all. My therapy is now concentrated on re-building strength in the muscles. I can shoulder a gun now, but there's no way I can do it really fast, and I'm not ready for the impact of recoil.
I'm thinking maybe in another month or so.By the way, I didn't have staples to close my incision. They used the steri-strip tape, as you can see in the photo. Also, this is my right shoulder. The photo being shot in the mirror makes it look like the left. I am a right handed shooter.
Good luck with your recovery.
