I'm having a hard time focusing on my Bisley, 7 1/2" front sight. I painted it years ago with Testors orange model paint. I noticed that the top 25% of the paint has worn off. Besides being 61 years old and wearing a bi-focal, I thought that might be part of the problem. So I stripped it tonight and I want to repaint it. Question is, what color? Flat black, white, or some other color? What would give the best contrast to the rear sight white outline for contrast? If this doesn't work, it's getting a red dot. What do you folks have to say?
