The XS Sights R3D 2.0 tritium night sights in orange (brand part no. GL-R201P-6N) are a standard-height 3-dot set for Glock 17, 19, 22, 23, 24, 26, 27, 28, 31 through 36, 38, 39, 45 and 47 pistols. A tritium lamp sits in both the front and the rear, and the front adds an orange photoluminescent glow dot for contrast in bright light. The rear is a wide notch with serrations and an anti-reflective lens, and XS finishes the set in Black Nitride for corrosion resistance. It is a traditional notch-and-post picture for carry and duty Glocks.
