The XS Sights R3D Tritium Night Sight Set for Glock 17/19/22-24/26/27/31-36/38 (brand part no. GL-R012P-6N) puts a fixed 3-dot tritium sight picture on your pistol, built for fast target acquisition when the light drops. XS machines the housings from steel for durability, then sets a green tritium front dot against an orange rear sight so your eye picks up the front dot first under stress. The rear sight edge is shaped to aid one-handed slide manipulations, and the set installs by hand or with a standard sight pusher tool.
