I recently got some TFO sights installed on a glock, and I am now shooting left. Before I got the sights installed I did not have this problem. At 12 yards my groups are tight and about 1-2 inches to the left of point of aim. I can compensate by holding to the right side of the target. When I hold right I am able to put shots in the middle of the target consistently. I couldn't be happier with the groups most shots are touching minus a flyer once in a while, but I am not hitting where I would like to. I am just looking for some advice about tapping the sights over to compensate or is it me pulling the trigger (I do not want to embrace a bad habit)?
