DXT Big Dot Night Sights provide faster target acquisition and easier sight alignment in low light environments. They feature a snag-free design for easy holster draw without catching clothing. The v-notch rear sight and large front sight provide easier target acquisition compared to factory sights. Tritium lamps aid alignment in dim and dark environments. Red dot battery boxes that measure 0.275 above the top of the slide will obscure the sights. XS Suppressor/Optic height sights will work with suppressors up to 1.375 in diameter and the Trijicon RMR as long as the battery box height is not above 0.250 above the top of the slide. In most installations it will not work with the Vortex Venom/Viper, and Burris Fast Fire Optics, as they are much taller.
