An undercut patridge front sight will be the best answer for sharpening and blackening a sight picture for most people. You'll have to use a custom, as none are available from the factory. The Bowen rear sight will also help, as the top and notch are crisp, as opposed to the factory blades that are not sharp edged and therefore reflect sunlight, etc. A problem with red ramps and fiber-optics is that they shoot to different points in different light conditions. The " bad" news for you is that the 2X scopes and red-dots will be the very best option, in the end, for most people on revolvers.
