The XS Sights SI0013S3Y, also known as the DXW2 Big Dot Tritium Night Sights, provide unparalleled front sight visibility regardless of lighting settings. These sights are uniquely designed to direct focus toward the front sight with the assistance of a high-contrast front and a clear V-notch rear. Distinguished for their innovative approach, the front sights utilise a patent-pending glow dot. This extraordinary feature absorbs light and commences glowing under low light conditions, functioning even before it\'s dark enough for the tritium to be visible.
