Fits M&P & M2.0 - Full Size, Compact, Shield, Shield Plus, Shield OR, 380 EZ, 9 EZ, and CSX Models Our DXT2 Night Sights for Smith and Wesson pistols are tritium night sights specifically crafted to enhance the performance of your EDC pistol. These defensive sights are meticulously designed with features to ensure optimal visibility in low-light conditions. The front sight utilizes a unique photoluminescent Glow Dot, which absorbs surrounding light and emits a gentle glow when lighting is limited. The convex shape of the dot provides a larger surface area, maximizing light absorption and intensifying the brightness of the Glow Dot. Our primary objective when designing the DXT2 sights was to make them large and highly visible, addressing common issues such as aging eyes and deteriorating vision. During our testing, we observed that the orange front sight is most visible in daylight, while the yellow variant glows brighter in low-light environments. The rear sight features a shallow V shape, ensuring a simple, low-profile design that offers an extensive field of view. To prevent confusion between the front and rear sights in high-stress situations, we adopted the "dot-the-i" sight picture. This sight picture consists of a tritium dot in the front sight and a tritium bar in the rear sight, facilitating quick and accurate target acquisition. In most gunfights, both the victim and attacker are in motion, with the victim primarily focused on the threat. The DXT2 Night Sights address these challenges by being big, bright, and easy to see, regardless of the time of day. XS DXT2 Tritium Night Sights serve as exceptional defensive sight choices for your pistol, ensuring the front sight remains visible regardless of lighting conditions. With these sights, you will be prepared for any potential confrontation, regardless of the lighting conditions you're in.
