Product Description The Night Fision Precision Tritium Night Sight Set for the Walther PDP redefines what you can expect from tritium gun sights. When conventional sights rely on aluminum sleeves and painted-on white rings, Night Fision breaks the mold with their patented injection-molded sleeve design. This innovative construction holds the tritium vials securely in place while simultaneously creating a brighter, more durable ring known as The Perfect Dot. The result is maximum visibility in both daylight and low-light conditions, giving you the confidence you need when it matters most. Featuring a distinctive orange front ring with white rear rings and a white center stripe on the rear sight, this set is built in the USA using Swiss Tritium and is compatible with the Walther PDP Compact 4", PDP Full Size 4", and PDP Full Size 4.5".
