Any particular reason to pick gold over brass? I assume it dosen't tarnish? I'm asking because I just picked up a surplus FN Hi Power and am going to send the slide to Novak for some sights. I was just going to throw some springs in it but decided "what the hell, lets do it up". I dont want something that will wear out (tritium) or something that may break (fiber optic) so I ended up on a brass or gold front. Just curious if the gold will be worth the cost.
I don't have experience with either, but from what I've read they have different optical properties, with gold being better in a wider range of lighting conditions. IIRC, if there's any ambient light, the gold will "pick up" the light and reflect it back, where brass won't. I don't know if that difference would matter in any significant manner, though.

I have a gold bead on my Beretta 92 Elite II. Love it. Prefer it to my FO for range use. For real use I still am a Trijicon HD guy, those are pretty much my favorite. Wish they made them std height though. Odd how tall they are.
