Who This Is For
The XS F8 Night Sights are ideal for Glock 17, 19, and 22 owners who carry for personal defense or use their pistol for home protection — anyone who needs to acquire a sight picture fast, whether at the range in bright sunlight or in a dimly lit hallway at 2 a.m. They're also a smart upgrade for competitive shooters seeking a sharper, faster sight picture over stock factory sights.

Frequently Asked Questions
Will the XS F8 Night Sights fit all generations of the Glock 17, 19, and 22?
Yes. The XS F8 Night Sights are designed to fit Glock 17, 19, and 22 pistols across Gen 1 through Gen 5. They use the same standard Glock dovetail dimensions and can be installed with a standard Glock sight pusher tool or by a qualified gunsmith. Always verify your specific model and generation against XS Sights' fitment guide before installing.
How do the F8 sights perform compared to standard three-dot night sights?
The F8 design prioritizes speed over precision at typical defensive distances. The oversized front sight with its vivid orange photoluminescent ring draws your eye instantly, while the wide rear notch reduces the need for fine alignment. Unlike traditional three-dot setups where the eye must balance all three dots, the F8 system naturally focuses attention on the front sight — resulting in faster, more instinctive target acquisition, especially under stress or in low light.
How long will the tritium in the F8 night sights remain effective?
Tritium has a half-life of approximately 12.3 years, meaning the glow will gradually dim over time. Most manufacturers, including XS Sights, rate their tritium vials for approximately 12 years of reliable luminescence. After that point, the sights will still function normally in daylight and the photoluminescent orange ring will still charge from ambient light — only the passive tritium glow in total darkness will diminish.
