My 74 year old eyes are having trouble with the red on the front sight picking up the red bullseye. I wonder if there is a green replacement? I checked the S&W company webpage and didn't see one. Any idea who would have one for sale? Just the green plastic, not the whole sight.
Go look at Brownells, or Midway and see if there is a "kit" for the replacement. There used to be and many different colors were available. I've seen blue, green, white, yellow, etc.
