Description
The XS F8 takes one of the biggest weaknesses on a stock Glock, those tiny factory sights, and fixes it with a bold front post that your eye locks onto instantly. The front sight combines a green tritium vial with a photoluminescent orange Glow Dot ring that soaks up ambient light and keeps glowing after dark. Pair that with a wide rear notch and you get a sight picture that's quick to find under bright sun, in a dim hallway, or anywhere in between.
What Makes the F8 Different From Stock Glock Sights
XS calls this the figure-8, 2-dot system for a reason. Instead of the traditional three-dot layout, the F8 simplifies the rear and stacks a single green tritium dot right below the big front dot, so your two glowing references line up into a figure-8 when you're on target. It cuts down the mental clutter in a hurry and pulls your focus straight to the front sight where it belongs. The rear also has an overhang that shades the tritium and knocks down glare in bright daylight, plus a front ledge you can use to rack the slide one-handed against a belt or holster.
Fit and Build on the F8 Glock Night Sights
These are CNC-machined from solid steel bar stock at the XS shop in Fort Worth, Texas, so they hold up to hard use and repeated holster wear. This set fits a wide range of Glock models including the 17, 19, 22, 23, 24, 26, 27, 31 through 36, 38, and 45. They run a touch taller than most traditional irons, which gives a natural sight alignment and lets them serve as backup irons on some optic-equipped slides. The front sight measures .280 inches tall and the rear comes in at .385 inches.
Installing Your F8 Night Sights
Installation is straightforward with a sight pusher tool, or a hammer and punch if you're careful and comfortable doing it. If you'd rather not chance it, any gunsmith can knock this out quickly. XS backs the tritium with a long-term warranty, so these are built to keep glowing for years of carry and range time.

Frequently Asked Questions
Which Glock models do the F8 night sights fit?
This set covers a wide spread of Glock pistols, including the 17, 19, 22, 23, 24, 26, 27, 31 through 36, 38, and 45. It works on Glock slides cut for the standard sight footprint. Double-check your exact model and generation before ordering to make sure the cut matches.
What color are the F8 sights and how do they glow?
The front post has a green tritium vial ringed by a photoluminescent orange Glow Dot, and the rear carries a single green tritium dot. The orange ring absorbs ambient light and stays visible in bright daylight, while the tritium keeps both sights glowing in total darkness. Together they form the figure-8 sight picture that gives these their name.
Can I install the F8 Glock sights myself?
Yes, these are designed to go on with a sight pusher tool, or a hammer and brass punch if you're careful. Many folks handle the install at home, but if you're not comfortable pressing sights a gunsmith can do it in a few minutes. XS also offers written instructions and an install video to walk you through it.
Are the F8 sights good for both self-defense and daytime range use?
They're built to shine in both. The tall, high-contrast front post pulls your eye downrange fast in a low-light or high-stress situation, and the orange ring keeps that same front sight easy to spot under bright sun. The steel construction and tritium hold up to regular carry and plenty of trigger time.
