I just purchased my first 1911, a used Kimber Custom LW. I have a few questions, that may be old info to some, or my gun may have a problem. The first is that the gun was pretty consistently hitting high, about 6-7 inches at 25 yard. The sight picture is weird. The red dot in the front sight is MUCH smaller that the white dots in the rear sight, so if i line the top of the sights up I get 3 dots like this 0o0 only upside down, with the center dot high. That's when it seems to shoot high. With the dots lined up center to center, the tops of the sights look weird, like --_-- but then it shoots a little more center. However, that is very difficult to be consistent. What am I not getting?
