I am looking for a manageable load for the wife/son to be able to use if I am not home. Full power ammo in the G27 is out of the question. I use factory ammo in my G22 for work/ccw and 3.5 TG under 180gr berrys plated for play. I loaded up some 155/165/180 GD's with 3.5 TG and played around with the G22 and it was very light/fun/manageable not sure on the velocity though as I dont have access to a chrono? They did still knock down the steel plates at 25 yards and was a lot of fun! Anybody guestimate the FPS on 155gr GD HP, 3.5-4.0 TG?
