If memory serves they moved away from the 10MM and then the .40.You lost me. I'm not trying to be argumentative... just stating my experience.
I can shoot faster followups with my G20 than my G23,no question. My guess is its because I have a better grip on the gun. A guy with smaller mitts will no doubt disagree. I run about 3 cases through my 17's and 19's every year....maybe if I spent more time with the 23....I might like it a little better.
Didn't the FBI move away from .40 due to poor marksmanship? Maybe I'm not the only one- grin
