First Impressions of XS Sight Systems R3D Night Sights for Glock Suppressor 43x & 48
For years, I’ve relied on factory Glock sights, finding them… adequate. But adequacy doesn’t cut it when seconds count, especially in low-light situations. When I recently decided to upgrade my Glock 43X, I knew I needed sights that offered superior visibility, especially as I started carrying more often. The XS Sight Systems R3D Night Sights for Glock Suppressor 43x & 48 immediately caught my eye due to their suppressor height, compatibility with red dot optics, and reputation for extreme brightness.
My primary goal was to enhance my Glock 43X’s low-light performance and allow for co-witnessing with a red dot sight I planned to add later. Upon opening the package, I was immediately impressed by the robust construction and the vibrancy of the tritium vials. The steel sights felt solid and well-made, inspiring confidence in their durability.
Compared to Trijicon HD XR sights (which I have on another Glock) and the factory Glock sights, the XS Sight Systems R3D Night Sights for Glock Suppressor 43x & 48 appeared to offer a unique balance. The Trijicons are excellent, but the thinner front sight can sometimes be harder to acquire quickly. I chose the XS Sight Systems R3D Night Sights for Glock Suppressor 43x & 48 because I felt they offered the best combination of visibility, brightness, and co-witnessing capability for my specific needs.
My first impression was one of excitement and anticipation. These sights seemed like a significant upgrade, promising improved accuracy and faster target acquisition, especially when using a suppressor or red dot. I couldn’t wait to get them installed and put them through their paces.

First Use Experience
I installed the XS Sight Systems R3D Night Sights for Glock Suppressor 43x & 48 on my Glock 43X using a sight pusher tool at my local range. My first outing was an afternoon range session followed by some drills as dusk settled.
The bright green front sight was instantly noticeable, even in daylight. The sights were easy to acquire and aligned quickly, making target acquisition significantly faster than with the stock sights. In the fading light, the tritium vials started to glow, providing a clear and distinct sight picture. There were no issues, and I was immediately impressed with the improved visibility.

After several months of regular use, the XS Sight Systems R3D Night Sights for Glock Suppressor 43x & 48 have proven to be incredibly durable. They have held up perfectly, showing no signs of wear and tear despite being exposed to sweat, dirt, and the occasional bump during concealed carry.
I regularly clean my Glock after each range session, and the sights require minimal maintenance. A quick wipe with a clean cloth is usually all it takes to keep them looking and performing like new. Compared to other night sights I’ve used, these have exceeded my expectations in terms of both brightness and durability. The robust construction and consistently bright tritium vials provide a reliable and confidence-inspiring sighting system.
