The XS Sights R3D 2.0 Tritium Night Sight Set for Glock 17-38, Orange (brand part no. GL-R201P-6N) updates the original R3D design with a refined square-front, notch-rear sight picture built for faster alignment under stress. The tritium front dot is ringed in orange for daylight visibility, while the tritium rear sight glows in low light so you keep a usable sight picture around the clock. The rear sight edge is shaped to aid one-handed slide manipulations, a detail that matters when you’re working the gun one-handed.
