On my full size SR1911 and my Commander the sights seem to be getting a little dim from what they used to be. On my Colt Commander (built in 1975) and with military sights, it's black on black and it hard to hit a black target at the range. Today I tried something to repair the sights. I went to our local Wal-Greens and picked up some liquid paper (the kind they used to use to wipe out typewriter mistakes and redo the paper) and got a tube of that. The tubes come out in a nozzle on it like super glue does and I used that to lighten my sights. It just so happens that the tip of the nozzle exactly fits the sights on my Rugers. I put it on and let it dry 3 times and can see they look a lot better. I don't know how long it will last but at $2.50 a tube, if they last a month that's better than changing out sights. Another thing I would like to know, has anyone changed out their sights on a Ruger and if so, what sights did you use or what sights would you recommend??? I know I don't want the fiber optics but would like other opinions about your likes or dislikes. I am going to try it on my Colt Commander and see how it works on military sights.
