Out of the 114 different powders I have info on Power pistol rates #32 on the relative burn chart. They are rated from #1 to #114 fastest to slowest. So there are powders available the can use a charge of almost 2 full grains less powder for results that will be fairly close. Good luck with whatever you decide on though
Currently I'm loading Berry's 124 grain plated with 6.0 grains of Hogdon H6 with C.O.L. of 1.15 and they shoot fine in my G17 gen 4. I don't have the fps reading, but they don't come apart and the action cycles fine.
