XS DXT2 Big Dot Night Sights (brand part no. GL-0015P-5N) bring the oversized, high-contrast Big Dot front sight to a suppressor-height profile, so the set co-witnesses cleanly with a slide-mounted red dot on Glock pistols spanning the 17 through 38 frame family. Tritium powers both the front and rear inserts on a steel body, keeping the sight picture visible day or night without a battery. It’s built for shooters who want the speed advantage of a Big Dot sight without giving up their optic.
