XS Sight Systems R3D Night Sights Features The XS Sights Night Sights Set uses tritium front and rear inserts to deliver a glowing sight picture usable in low light and full darkness. The front sight pairs a green tritium vial with a green outline making it stand out quickly against the rear notch during target acquisition. A photoluminescent glow dot is built into the sight to absorb ambient light throughout the day allowing it to glow brightly during dusk and dawn transitions when tritium alone is harder to see. This layered approach to visibility gives shooters a consistent sight picture across a wider range of lighting conditions than standard tritium sights alone. The rear sight features a wide notch design paired with an anti-reflective lens that reduces glare from overhead or side lighting. Together the front and rear sights create a traditional 3-dot tritium notch and post sight picture that shooters already familiar with iron sights can pick up quickly. Manufactured in Fort Worth Texas this set is purpose-built for the Glock 42 43 43X and 48 pistols. Sold in a bulk pack of 20 sets this listing suits dealers and shooters looking to equip multiple compact Glock pistols with upgraded night sights.
