Trijicon HD Night Sight Set for Smith & Wesson M&P Shield, Yellow Front Outline
The Trijicon SA139-C-600721 HD night sight set provides a yellow front outline for compatible Smith & Wesson M&P Shield pistols. Green tritium lamps illuminate both sights, and the rear uses black outlines around a U-shaped notch.
Trijicon lists the M&P Shield in 9 mm, .40, and .45, together with Shield Plus and Shield M2.0 models. Shield EZ is explicitly excluded. This SA139 configuration is separate from the SA137 sights for the larger M&P family.
The Shield-specific front blade is 0.185 in. high, with a 0.262 in. rear blade. Photoluminescent front paint adds the colored outline, while the tritium lamps provide battery-free illumination. Aluminum lamp cylinders, silicone cushioning, and sapphire caps protect the illuminated elements.
