XS DXT II Big Dot Night for Glock 42, 43, 43X, 48 Green/Yellow Outline Tritium Handgun Sight Review

The XS DXT II Big Dot Night for Glock 42, 43, 43X, 48 Green/Yellow Outline Tritium Handgun Sight Made a Bold First Impression

For years, I’ve relied on standard iron sights and the occasional red dot. However, the call for quicker target acquisition in low-light scenarios became increasingly urgent. The XS DXT II Big Dot Night for Glock 42, 43, 43X, 48 Green/Yellow Outline Tritium Handgun Sight promised a solution and after many range trips I can safely say, delivered.

I wanted something that improved my sight picture under duress and low light. Standard 3-dot tritium sights work, but felt too cluttered and precise for close-quarters, high-stress situations. Upon opening the package, the sheer size of the front sight on the XS DXT II was striking. It felt like a deliberate and confident design choice from XS Sights.

I considered Trijicon HD sights, and Ameriglo CAP sights but they felt too similar to existing setups I’ve used. The XS DXT II Big Dot stood out with its unique “dot-the-i” configuration. My initial reaction was a mix of excitement and apprehension; would such a large front sight be accurate, or would it obscure the target? Only the range would tell for sure.

Real-World Testing: Putting XS DXT II Big Dot Night for Glock 42, 43, 43X, 48 Green/Yellow Outline Tritium Handgun Sight to the Test

First Use Experience

My initial testing ground was a local indoor range, transitioning from bright light to simulated low-light conditions. The immediate difference was the speed at which I could acquire the front sight. The large, bright green dot practically jumped into my vision.

Under dim lighting, the tritium began to glow, providing a clear and distinct sight picture. Recoil management with the Glock 43X felt unchanged but my target acquisition had improved drastically. The only snag arose initially with longer-distance shots; the dot naturally covers more of the target at 25 yards.

Extended Use & Reliability

After several months of consistent range use and incorporating the XS DXT II into my EDC rotation, my confidence grew. The sights held up remarkably well, showing no signs of fading or damage. Cleaning was simple; a quick wipe with a cloth kept the lenses clear.

Compared to standard iron sights, the XS DXT II provides a dramatic improvement in target acquisition speed, especially in sub-optimal lighting. The bold sight picture made transitioning between multiple targets faster. However, it requires conscious effort to fine-tune long-distance accuracy due to the size of the front dot.
