I have an old “CRONY”, and here are some results of WW 135’s through my G34 Glock (5.25” BBL). I know the results are somewhat different than others.
1078 fps 5.8 g HS-6
1036 3.6 g Tight Group
957 3.2 g ” ”
956 4.0 g Auto Comp
1065 4.5 g Auto Comp
1163 5.2 g Auto Comp
959 4.0 g CFE Pistol
1053 4.4 g CFE Pistol
P.S. the G34 has a 10 # recoil spring, all locked back the slide last round.
I don’t care what the power factor is.
