The XS F8 Night for Glock 20/21/29 Tritium Handgun Sight Made a Bold First Impression
Night sights are a critical upgrade for any serious shooter, especially those who carry for personal defense. When the sun goes down, standard sights become virtually useless, and that’s when the XS F8 Night for Glock 20/21/29 Tritium Handgun Sight really shines, literally. Manufactured by XS Sights, these sights are designed to improve target acquisition in low-light conditions for Glock models 20, 21, 29, 30, 30S, 37, 40, and 41, providing a green tritium lamp surrounded by an orange outline in the front sight and a green tritium lamp in the rear.
I’ve always prioritized low-light performance in my firearms. After a near miss during a nighttime encounter several years ago, I vowed to upgrade all my carry pistols with quality night sights. I’ve tested several brands, but was drawn to XS Sights based on their reputation for ruggedness and innovation in sight design.
The XS F8 Night for Glock 20/21/29 Tritium Handgun Sight arrived in a no-nonsense package, well-protected and ready for installation. Picking up the front sight, I immediately noticed the bright orange outline around the green tritium vial. It felt robust and precisely machined. This stood in contrast to some cheaper aftermarket sights I’ve handled that felt flimsy and poorly finished. Compared to Trijicon HD sights, which are excellent but a bit pricier, and Ameriglo Spartans, which I found less intuitive for quick target acquisition, the XS F8 promised a faster, clearer sight picture.
From the moment I unboxed them, I was impressed. They appeared well-made, and the design seemed to prioritize rapid target acquisition, exactly what I was looking for in a defensive firearm. I was excited to get these sights installed and tested on my Glock 20.
Real-World Testing: Putting XS F8 Night for Glock 20/21/29 Tritium Handgun Sight to the Test
First Use Experience
I mounted the XS F8 Night for Glock 20/21/29 Tritium Handgun Sight on my Glock 20 and headed to an outdoor range that allows for low-light shooting after dusk. The initial range session focused on drawing from concealment and engaging targets at 7, 15, and 25 yards. The enhanced visibility in low light was immediately noticeable.
The bright orange outline on the front sight made it incredibly easy to pick up in dim conditions. Even when shooting in a light rain, the sight picture remained clear and distinct. I found the i-Dot sight configuration, with the single tritium dot on both the front and rear sights, surprisingly intuitive, naturally guiding my eye to align the sights quickly.
Extended Use & Reliability
After several months of regular use, the XS F8 Night for Glock 20/21/29 Tritium Handgun Sight has proven to be remarkably durable. I’ve put several hundred rounds through my Glock 20 since installing these sights. There are no signs of the tritium vials dimming or any physical damage to the sight bodies.
The sights have held zero consistently, and the finish has resisted scratches and wear despite daily carry. Maintenance is straightforward – a quick wipe down with a lightly oiled cloth after cleaning the pistol is all that’s needed. These outperform the factory Glock sights by a significant margin in low-light scenarios. And they provide a faster sight acquisition compared to some three-dot systems I’ve used in the past.
