High-visibility sight combinations put you on target faster in high stress or low light conditions by pulling your eyes to the front sight. Sight set includes non-tritium, white line V-notch for the rear sight, green tritium dot surrounded by a white ring for the front. Low profile, no-snag design is great for carry and combat competition guns. Matched sight sets offer direct replacement of factory sights. Big Dot (BD) front sight has a large, easy-to-see white ring surrounding the tritium dot. Airlite Ti replaces pinned front sight on fixed sight guns, requires drilling for pin. Mfg: Xs Sight Systems
