I know everyone talks about replacing the rear sights because they are polymer, not metal. I'm one that figured if the frame is polymer, then the sight should be fine. I have always hated the rear dots. Mine were not symmetrical and very obnoxious. Today I got tired of it and took a piece of 220 sandpaper to the rear sight. All I have to say is that blacked out rear sights are the way for irons. No sharpies. No paint. No chemicals. Just a few minutes of careful sanding.
