The Trijicon DI Night Sight Set combines daylight-bright performance with constant aiming points for Smith & Wesson M&P M2.0 SD9 VE and SD40 VE models, delivering a dual-illumination solution that pairs a green fiber optic front sight with a tritium-backed rear sight featuring a black outline for rapid alignment in any light. This patent-pending design introduces an industry-first interchangeable fiber, allowing field replacement and the customization of fiber and ring retainer colors to tailor a personalized aiming solution that stays bright from full daylight to total darkness. Built with Trijicons proven dual-illumination technology, the fiber is chemically and thermally robust and finished using the same meticulous technique as the ACOG, while the tritium lamp is capped with a sapphire jewel to maximize durability and brightness. The result is an ultra-bright, reliable sight picture that maintains a consistent point of aim, improves target acquisition speed, and enhances accuracy across a range of shooting scenarios, making these DI Night Sights a practical upgrade for serious handgun users seeking dependable performance under varying lighting conditions.
