I vote for idea on shaving the comb to the correct height for you. I've done it on more than one gun. But first, shoot the gun at a steel patterning plate (w lead shot) three times from 16 yards. If you bring the gun up and fire at the plate w/o aiming deliberately as you would if patterning the shot load, the pellets will tell you where that gun hits for you. Treat the comb accordingly...
