I had the same problem. I would always shoot
4-6 inches left but kept a good group. Had rear sight
Pushed all the way right still shot left 3-4 inches.
Changed out the rear sight to a tactical aiming solution.
I have nothing but great things to say about it. Even at
30 yards hitting right on target. Only thing to focus on now
Is elevation! Rear factory sight to me was to wide and was
To much trouble to get it perfectly Aligned. Plus new sight picks
Up on targets fast.
