Trijicon HD Night Sights (part no. SA137O) are a fixed 3-dot sight set built for the Smith & Wesson SD9VE and SD40VE, made by Trijicon. The front sight uses a wide orange photoluminescent ring around a tritium vial, giving a bold, fast-to-find aiming point in daylight that keeps glowing under tritium power after dark, while the black rear notch stays low-glare so it doesn’t compete with the front dot.

Frequently Asked Questions
