I went and shot my G22 (G3), G23 (G3), & G27 (G4) today. I am going to try to make Wednesday's my range day. I put 50 rounds through each pistol. I shot @ 7 yards trying to work on technique. I shot my G23 first, American Eagle 180 grain, nice groups, but a little low left. I then shot my G22. 5 ten shot groups, WWB 180 grain, all well centered, smaller than my fist. Then I shot the G27. I don't think I could hit the broadside of a barn with that little sucker. WWB 180 grain. Pie plate sized groups, all low left. Pretty disappointed with it so far.
I was really trying to make sure I staged the trigger between shots and tried to make sure I was bringing the trigger straight back. I changed my grip and trigger finger placement around, trying to find the sweet spot, no dice. Nothing I did would help.
Next Wednesday I am going to try it with no backstrap and a couple different loads. I also took the grip adapter off the G23 to see if it helps that one.
