As a Firearms Instructor I can tell you that GC is absolutely correct which of course he already knew. What amplifies the problem is that fact that there is WAY MORE hand than grip space on small compacts and your modifying your grip, somewhat, compared to your full size frame pistol. That is for the guys shooting low left. Trigger mods are not an option in my line of work but I can see how a lighter breaking trigger could improve the situation. Getting use to the gun by shooting it alot will help tons. For Mark.....First step, as stated, is to make sure its the gun and not you. Having someone, with high level experience with a handgun, help you would be great. If you cant, then try to set up a bench where you can get some support, put a small dot on the target at about 5-7 yards, and concentrate on sight alignment and trigger press. Go slow and methodical. If your shooting ABOVE line of sight, by a long ways at five yards, and doing it consistent, then something is wrong. I have the same gun, which I carry as a back up, mounted to my vest, under my uniform shirt. Never had an issue but I make a living with striker action pistols. It very well could be the gun but I would be surprised.
