It sounds like your trying to anticipate the recoil, and your are jerking it to the left. I did the
same thing when I got my G23 but I dry fired and let the trigger break surprise you and Now it's better yet I'm dead on. It's not the gun. You may also have too much trigger finger in the trigger well.

Don't know if your are left or right handed, but you may have too much/little finger on the trigger. Experiment a little and I think you will dial in on the problem.

I think you might need to square your grip up a little. It sounds like you are also jumping a bit when the gun fires. Try shooting really slow, at least make sure to press the trigger really slow, and get rid of that as a possability. Then look at your frame and make sure your hand is as far up as it can be on the grip and try moving until you get it straightened out. I'm no coach or shooting pro but its worth a shot. I had a similar problem when I first started shooting my glocks and it was all in the grip. I figure you are not doing this but be sure you don't have your thumbs crossed also.

anticipating recoil. Your grip may need work but the anticipation is why you can get the first few on target and then you go downhill from there.

I agree with the anticipation comments. This just means you need to go to the range and shoot. The busier the range the better. Its like training a bird dog not to be scared of the gun. You have to condition yourself to get used to the bang. I will even take my ipod in and put music on just to mask some of the percussion sound around me. I use a drill when I find myself flinching. You have to get in the zone. I raise my weapon and line my sights on the target. Channel all your focus on the target just past the front sight. Having the target closer than normal than you would usually shoot will help. Don't focus on the trigger break as much as you are focusing on the target. When you have a clear mind and nothing but the target is in focus slowly and smoothly start bearing down on the trigger while concentrating on the target. Slow and methodical is the name of the game. If you do this for a magazine or two, you should be able to back the target up and do this over and your patterns should start getting better. It would benefit you to do a drill like this with the first magazine every time you shoot.

Sure enough though when I slapped another mag in the same thing happens again 2 or 3 rounds dead center and then the others straight up and left of center. Thanks for the help and suggestions. Do you think adding a 3.5# trigger would help?

3.5 connector helped me greatly.
