With a 642 I use Testor's model paint to paint the bottom half of the front sight flat black and the top part gloss orange. So basically, I create a sight picture similar to a blued gun with an orange insert. I use a sharpie marker to blacken the rear sight. Overall, this creates an acceptable sight picture.
