The XS Sights DXT2 Big Dot Night Sights (brand part number SW-0039S-5Y) are defensive tritium sights built for the M&P M2.0 optics-ready full-size and compact pistols across 9mm, .40 S&W, .45 ACP, and 10mm. XS Sights built the front sight around a proprietary photoluminescent Glow Dot that absorbs ambient light, with a convex shape that increases surface area and intensifies the glow in low light. This particular set uses a yellow front dot, which XS Sights found glows brighter in low light than the orange option, paired with a tritium bar in the rear for a dot-the-i sight picture that keeps front and rear from being confused under stress. The shallow V rear sight has a simple, low profile that gives a wide field of view, and the whole DXT2 line is designed to be large and highly visible, helping shooters with aging eyes or deteriorating vision pick up the sight faster.
