Trijicon HD XR™ Night Sights - Smith & Wesson M&P / SD9 / SD40 SA637-C-600850

The S&W M&P and SD9 VE series are trusted for their ergonomics, but to truly master these platforms, your aiming system must deliver precision at any range. The Trijicon HD XR Night Sights (MPN: SA637-C-600850) address the needs of shooters who require more than just a close-quarters solution. By utilizing an Extended Range design, Trijicon thinned the front sight post to provide a much larger field of view, which is essential when engaging targets at increased distances.

Traditional Tritium night sights often feature thick posts that can obscure a target at twenty-five yards. The Trijicon HD XR solves this by allowing more light on either side of the front post within the rear U-notch. This creates a refined sight picture for precise identification and clear visibility of hit locations. Whether you are a competitive shooter or a professional, seeing more of your target leads to faster, more confident decision-making under pressure.

Visibility is critical during the "gray time" between day and night. These Trijicon Night Sights feature a high-contrast photoluminescent yellow outline on the front post that serves as a speed ring, instantly drawing your focus during a draw. In total darkness, the self-luminous Green Tritium lamps take over. These battery-free lamps provide a reliable three-dot aiming point, ensuring a consistent point of aim for S&W M&P Yellow Night Sights users in any environment.

The construction of these pistol sights is built for durability. Each lamp is protected by a sapphire window and an aluminum cylinder to shield it from solvents and heavy recoil. The rear sight also features a steep, hooked surface for emergency one-handed slide manipulations. This set fits M&P, M2.0, and SD series models, offering a professional-grade upgrade.
