XS Sights' F8 Night Sights for Glock are a top-of-the-line choice for those looking to upgrade their factory-installed sights. Designed with a large, high-contrast front post, these sights are built for fast sight acquisition and increased front sight focus, making them an excellent option for self-defense scenarios.

The tritium-powered front and rear sights provide exceptional visibility in low-light conditions, and the photoluminescent orange Glow Dot on the front sight absorbs ambient light and glows in the dark. The figure-8, 2-dot alignment system simplifies the rear and draws focus to the front sight for accurate indexing. These sights are taller than most traditional sights on the market, providing a more natural sight alignment and serving as backup iron sights for some pistol reflex sights.

These sights are also highly versatile, as they fit standard holster options and co-witness with EOTech EFLX on factory machined slides. The rear sight overhang reduces glare, and the anti-reflective rear tritium lens ensures clear sight picture even in bright sunlight. The rear sight ledge also allows for one-handed slide manipulations.

XS Sights' F8 Night Sights for Glock are an excellent choice for anyone looking to improve their low-light shooting performance. With their durable construction, high-visibility design, and easy installation process, they are an excellent investment for those who take their firearms seriously.

    F8 night sights

    Posted by Randy B on May 28th 2023

    Have now put these on all of my Glocks. Perfect solution for 63 year old eyes. The big front dot gets you on target quickly and the large rear aperture gives you the opportunity to fine tune your shots when you have the time to do so.

    F8 Sights - Great sight picture and easy install

    Posted by Bill L on Mar 18th 2023

    Absolutely pleased with these sights on my Glock 43x MOS. Such a clean and easy installation, unlike some competing products. Great sight picture with a Holosun EPS Carry mounted on C&H plate. Very pleased.

    Best night sight! Super bright in total darkness. I may have damaged the front sight upon installation because it didn't glow and looked damaged. I emailed XS, got a response same day, s new front sight arrived three days latter! Customer service is equal to the quality of their product! I will only purchase XS products in the future. Many thanks to XS! If only they made firearms.

    F8 sights

    Posted by J. J. Isherwood on Jul 2nd 2022

    These are excellent sights with excellent customer service. The Big Dot DXT's are probably a better fighting sight if used under bad environmentals or while moving/clearing a building. But the F8s are a good compromise between traditional notch and post to use on the range and the Big Dot. They allow rapid acquisition with a very prominent orange dot on the front while also preserving aiming for longer distance shots (the DXT's CAN be shot at longer range accurately but take a very conscious effort to line up the dot exactly tangent to the wide V--great for night or bad envrions or fighting from difficult positions but somewhat harder to work day VFR on the range). The F8s sit fairly proud and can be used to help rack a slide if necessary; very well built and rugged. IF you're looking for a traditional type of sight which can be rapidly acquired along with a good straight-8 configuration these are the sights to get. Mounted on a Glock 33.
