XS offers a hand-polished brass bead; the convex face reflects more light than flat-faced factory or competitor offerings, allowing for the cleanest view and the best reflection of ambient light. Brass is less expensive and more durable than gold, and this bead is hand polished using Flitz polishing products with a light protective layer that will minimize oxidization. Brass does not replace tritium on an EDC revolver; the retro classic brass front sights are optimized for range or field use.
