I use different approaches on my handguns. I put a Hi-Viz fiber-optic front sight on my 5 inch GP100 and really like it. You have a choice of red, green, or white pipes to use on it, and I seem to prefer the red on that revolver. The pipes are a little larger in diameter than normal and it really shows up well on that revolver. Then on My MKII Target pistols I just have Testor's florescent orange paint on the front sight and like that. My Smith & Wesson Victory came with green fiber-optic front and rear sights, and they are OK but I feel at some point I will probably go to something else but not sure what it will be.
