XS R3D 2.0 FOR GLOCK 21 Suppressor Height Green Review

The XS R3D 2.0 FOR GLOCK 21 Suppressor Height Green Made a Bold First Impression

As someone who has spent over a decade immersed in the world of tactical gear, I’ve seen countless handgun sight systems come and go. However, the XS R3D 2.0 FOR GLOCK 21 Suppressor Height Green immediately grabbed my attention with its promise of enhanced visibility in low-light situations and compatibility with suppressor-equipped Glocks. The combination of tritium and a high-contrast front sight seemed like a significant upgrade for my Glock 21, a pistol I rely on for both personal defense and recreational shooting.

My aging factory Glock 21 sights were dimming, proving inadequate in the dusk scenarios common at my rural property. I needed a robust, suppressor-height solution that could handle the added bulk of a suppressor and offer superior visibility.

Upon unboxing the XS R3D 2.0, I was immediately impressed with the robust construction and the vibrant green outline of the front sight. The sights felt solid, and the BlackNitride finish promised excellent corrosion resistance. Compared to standard aftermarket sights, the XS Sights offering had a distinctly premium feel, particularly with the thoughtful design of the rear sight ledge for one-handed slide manipulations.

I considered Trijicon HD sights and Ameriglo GL-429 sets, but the XS Sights R3D 2.0’s focus on a large, easily acquired front sight and its reported compatibility with a range of red dot optics on MOS-equipped Glocks ultimately swayed my decision. My initial excitement centered around how easily I’d be able to acquire a sight picture in less-than-ideal lighting conditions.

Real-World Testing: Putting XS R3D 2.0 FOR GLOCK 21 Suppressor Height Green to the Test

First Use Experience

I first tested the XS R3D 2.0 FOR GLOCK 21 Suppressor Height Green at my local outdoor range. The range offered both daylight and low-light shooting bays, allowing me to evaluate the sights in varied conditions.

The high-contrast green front sight immediately proved its worth, offering exceptional visibility in bright sunlight. Transitioning to the low-light bay, the tritium lamps glowed brightly, providing a clear sight picture without being overly distracting. The sight acquisition was significantly faster compared to my old sights, and the suppressor height allowed for unhindered aiming with my suppressor attached. There was a minor adjustment to sight picture required due to the increased height, but it was quickly mastered.

Extended Use & Reliability

After several months of consistent use, the XS R3D 2.0 FOR GLOCK 21 Suppressor Height Green sights continue to perform flawlessly. I’ve put them through approximately 1,000 rounds, including various drills and scenario-based training exercises.

The BlackNitride finish has held up incredibly well, showing no signs of wear or corrosion despite exposure to sweat and the elements. Maintaining the sights is simple; a quick wipe with a clean cloth after each range session is all that’s required. Compared to my previous experiences with cheaper sight options, the XS R3D 2.0 system has exceeded my expectations in terms of durability and performance.
