I know I've restated this many times to you vic, but for the others reading this thread. Low left groupings are not because of the gun or the sights, it's because incorrect grip or trigger pull or any combination of the two. My groups(if you could call them groups) were low left when I first got the 24/7, after blaming the sights and the gun, I tried blaming myself and correcting my shooting problems then magically I group.....near the bullseye(I seem to like to hit the line all the way around the ring). If you try the dry firing excersises you will be amazed at how much the sights move with just the trigger pull. And, when I did a few fast firing shots, when I didn't pull the trigger hard enough, I would jerk the gun down and to the left with no shot or recoil............I wonder why my shots hit there when I did fire the gun?????
