If you want something distinctive and functional, you can get more of a biege -- gold finish, one that's harder than melonite or tenifer, (Rockwell 74 hardness) by having the slide and barrel finished in nickle boron for about $100. It's harder, produces less friction on moving parts and requires less cleaning too. I am not sure if that would void S&W's splendid lifetime warranty, so that's something you might want to consider/check before making some changes to your firearm.
