The DXW2 Big Dot Night Sights represent the evolution of express sight philosophy—a concept born from African big game hunting and refined over 25 years for defensive pistol use. These sights prioritize what matters most in a gunfight: acquiring your front sight quickly and maintaining focus under stress.
XS Sights engineered the DXW2 system around a fundamental principle: in defensive situations, seconds count. The front sight must be large, bright, and immediately visible—whether in daylight or darkness. The wide field of view provided by the low-profile V-notch rear sight keeps your threat picture in focus while your eyes naturally center on the dominant front sight.
Front Sight: The 0.188-inch convex yellow dot combines tritium illumination with a patent-pending photoluminescent glow compound. The yellow optic absorbs ambient light efficiently and glows brighter than other colors in low-light conditions. The increased surface area of the convex design intensifies light absorption, charging the glow properties faster and maintaining visibility longer.
Rear Sight: Features a non-tritium white stripe that provides contrast without competing for your attention. The simple dot-the-"i" sight picture—tritium dot front, white stripe rear—prevents confusion during high-stress situations when fine motor skills deteriorate.
These sights fit Glock models 42, 43, 43X, and 48. Minor filing may be required for proper dovetail fit. Do not use a sight press or pusher tool during installation.
The DXW2 Big Dot sights deliver the visibility and combat accuracy that defensive shooters demand.
