Frequently Asked Questions
How do the DXT2 Big Dot sights perform in daylight compared to low light?
The Optic Orange front dot is engineered to be highly visible in all conditions. In bright daylight, the bold convex dot shape and high-contrast orange color provide a fast, clear sight picture. As light fades, the photoluminescent glow dot activates — bridging the gap between daytime and true darkness. In total darkness, the tritium insert takes over, giving you a self-illuminating aiming point without any external power source.
Will these sights fit both the Glock 42 and the Glock 43?
Yes. XS Sights designed this specific set for the Glock 42 and Glock 43 platform. Both pistols share compatible sight dimensions, so the DXT2 Big Dot set is a confirmed fit for either model. Installation typically requires a standard sight pusher tool or can be performed by a qualified gunsmith for best results.
How long does the tritium in these night sights last?
Tritium is a mildly radioactive gas that naturally decays over time, gradually reducing brightness. XS Sights backs the tritium vials in the DXT2 with a 12-year warranty, and the inserts typically remain usefully bright well beyond that window. The photoluminescent glow layer supplements the tritium during the early stages of low light, so you benefit from two distinct illumination systems working together.
