My 9mm loads for pistol clock at about 1100 fps when shot through the CZ and Hi-Power.
Running through the UZI with the anteater, michigan legal, and weird looking barrel they clock about 1400 fps.
I am using 124 fmj. No issues at all.
I would use 115g or 147g and not think anything about it.
Just go out and shoot and have fun.
