You might try a little nail polish on the front sight, that really helps me to pick it up faster, especially if the back and front start out the same color. I just stole some from the girl, and tried a few different colors till I found what best worked for me. The good thing about this is that if you don't like it, or get tired of it, you can just scrape it off, or if you are worried about your pistol, use cleaner to take it off. They make sight paint... but nail polish works fine for me. One thing I've seen, but never tried, is I saw a fella who got a little plastic jewel, and glued it to the back of his front sight, to make it sorta fake fiber-optic, seemed strange, but he liked it.
