Sometimes when I'm trying to get a perfect 6 o' clock hold on an NRA style target, I have this problem where there's a small sliver of white between the top of the front sight post and the black. Even when I move the front sight up into the black circle, there's still this thin white line. This makes it hard to know if I am holding in the same place every time.
Is that a defect of the eye, or something to do with the sights, that I can fix?
