So I used to own a G23, my home was broken into in 2009 and it was stolen. I shot it pretty well. I am more of a rifle/shotgun guy than a pistol guy but I shot it fairly well. Well the break-in has screwed with me mentally, and have since replaced the 23 with a 27. I havn't shot it much but it always shoots low/left for me. Went to the range the other day with my bro who has a 27 and 23. I shot both of his and they shot the same way, so he shot mine and had no problem. So i decided it's me. Then I found if i relax my grip, i can make very tiny groups! But the problem I have is it makes me feel like the pistol is jumping out of my hands....if i grip it a little tighter, we are back to low/left. How do I get rid of this? I shot his 23 thinking it was the 27 that was not fitting me like the 23 used to, but it did the same thing.
