Take your carry revolver to the next level with the XS Sights Standard Dot Tritium Front Sight. Installs easily (pin hole must be drilled) and offers a vast upgrade over standard sights, with an easy to see tritium insert. The XS Sights standard dot is 30% smaller than the Big Dot but is still larger than the industry average. The standard dot offers more precise shot placement while remaining a solid defensive option.
