My 1911 GI front sight glares in bright sun light. Is there an easy modification to reduce the glare? I don't want to bother replacing the sight. I know it is common to paint the sight, but I doubt it would be effective in term of reducing glare. Consider to cut fine serrations on the rear side of the half round sight blade with a needle file, but I can't think of an easy way to make even cuts. Is there a good way doing that?
