I had two old boxes of 110gr +P HP's, the hot W-W "treasury" stuff, that I picked up at a gun show. To burn it up, I used it to qualify with a 642 a few years ago, 50 rd course of fire, you go through twice, back to back. I'm very recoil tolerant but this stuff was pretty brutal. In spite of the recoil and muzzle blast the gun was fine after the 100 rounds, I didn't fare so well and ended the session with a sore wrist and two bruised up fingers. It was at least as bad as my friend's M&P340 with 125gr magnums. Anyway, your gun is plenty tough and will handle whatever you can.
