Light Pipe Sights
The sights (Fiber Optic Lumi Sights) are made by Cylinder and Slide and cost about $100 from them. As I recall, I got this set from Brownell's for a little less.
The sights are well made steel (except for the lightpipes). You can have any combination of red and green on both front or rear. They work great for me - age has robbed me of the ability to see black sights against many backgrounds, but I can see these just fine. I have since changed the front to an SDM light pipe just because of its serrated back edge, but that's just a personal preference. There's really nothing wrong with the C&S front, but I have SDM's on all my other 625's so I changed it for consistency of view. Both fronts have a square post profile and the rear has a square notch for extra precision when you need it. I've been using this rig in USPSA for the last two years, and the sights have had no problems.
