I keep looking at the TruGlo fiber/tritium sights thinking that the fiber would bend and for the triangle and the two slants. It would take more technology that I have at hand to do it. Fiber is picky and doesn't like sharp bends, but there's no reason why the vials couldn't be to the left and right of the front sight, just like they would be on the rear. The illumination comes from the side of the fiber, so other than looking a little clunky, it would work.
