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.
It isn't just cycling... Try running 1008 fps with a stock Glock weak hand only and get back to us.... Dave Sevigney runs 940 fps with 147 grain AA loads... 138 Pf take that s a hint
Ask you buddy to group that 1008 fps load out to 25 then 50 yards.... that will tell you the truth.
My 135 Pf Bear Creek moly load will group 2 inches off sand bags at 50 yards out of both my Spartan 9mm and G34... will yours?
BTW, my 3 random loads chronographed officially at Washington State IDPA Championships at 1019, 1020, 1020... the consensus at state last year was known to be generous.
