1008 fps is all that's necessary for a 124gr 9mm. Of course you'll want to go a little over that to make sure you don't stray below, but that seems a little excessive...
Mine: 124gr MG JHP, 1.085 COL, 3.6gr BE with a CCI 400 primer. Does 1025-1050 fps out of my gen4 g17. Chrono results show about 20 fps faster from a 34. It's plenty hot to cycle a gen4 reliably.
My buddies Gen3 34s like this load too.
