Over the period of looking I have not seen many night sights for revolvers. I have seen a few for ruger red hawks that look great! Are their some available for my ruger super Blackhawk with a 7.5 inch barrel? I'm not sure why night sights have not caught on as fast for revolvers. Is one of the main reasons that they are harder to install on a revolver? They are fairly easy on a auto pistol slide.
