The fail-safe, maintenance-free green Tru-Dot Tritium Rear Night Sight from Meprolight does not require any external power source, and provides years of usable illumination in all weather and light conditions. It replaces the stock rear iron sights on Walther P99 and S&W 99 pistols.
The U-shaped sight has green dots on either side of the opening to easily draw the eye to the pistol's center line for quick target acquisition and tracking. The sight is made from lightweight and durable aluminum with a chip, scratch, and corrosion-resistant anodized finish to stand up to years of use.
