Introducing the Big Dot and Standard Dot night sights: the ultimate tritium sights for defensive purposes, meticulously crafted to elevate your defense firearm to unprecedented heights. These sights boast a proprietary photo-luminescent glow dot that adeptly absorbs ambient light, subsequently emitting a potent glow during low-light conditions. The distinctive convex dot configuration is ingeniously designed to maximize light absorption, thereby enhancing the intensity of the glow dot's charge. Their ample and strikingly visible dimensions make these sights exceptionally versatile, catering to a range of challenges, from age-related vision changes to diminishing eyesight. When in daylight settings, the vibrant orange front dot takes center stage, while under low-light circumstances, the choices of brilliant yellow or green options come to life, providing unparalleled visibility.
