Night Fision Night Sight Set Glock 20/21/40 White Front U Notch Blank Rear Black Nitride

When it comes to tritium gun sights, aluminum sleeves and painted-on white rings are the norm. Night Fision breaks the mold, literally. The patented, injection molded sleeve design not only holds the tritium vials securely in place, it creates a brighter and more durable ring, called The Perfect Dot, that provides maximum visibility both day and night.
