I want to replace the sites on my 29-3 with meprolights if I can. I have an astigmatism and the night sights help with sight aquisition in all light conditions. My question is, has anyone replaced their red ramp insert on the front sight with the meprolight? I see they make one to replace the red ramp insert but from the picture it does not seem like it will fit the same as the original insert does...it looks to be a different shape. It might be that the bottom of the meprolight sight is the same shape, and it actually would protrude out from the ramp...not really sure. If anyone has installed the meprolight sight in place of the red ramp insert and can post a picture of what the finished product looks like that would help me decide if I wanted to go this route or not.
