XS DXT2 Big Dot Night Sights (brand part no. GL-0015P-5Y) bring a suppressor-height profile to the Big Dot platform, giving Glock owners running a slide-mounted red dot a fast, co-witness-capable set of backup irons. The yellow front dot measures a genuine 0.188 inches, tritium-powered for constant visibility, while a low-profile V-notch rear sight improves visibility of that front dot for a simple dot-the-i sight picture. A white-outlined rear sight with a tritium center and a rear ledge built for one-handed slide manipulation round out a set backed by a 10-year warranty.
