The XS DXT2 Big Dot suppressor height night sights for Glock (brand part no. GL0015P5Y) are a tall tritium front and rear set with a yellow Glow Dot on the front sight. XS Sights sizes the suppressor height set to clear a mounted optic and to serve as backup iron sights, and it fits the Glock 17, 19, 22, 23, 24, 26, 27, 28, 31, 32, 33, 34, 35, 36, 38, 39, 45 and 47. A tritium vial sits in the center of the yellow dot, and the shallow V rear sight has its own vertical tritium vial. Together they make the maker’s dot-the-i sight picture, a big dot over a line. It suits a Glock that needs sights taller than the factory set.
