The XS Sights DXW2 Big Dot tritium night sight set brings serious visibility to your Glock 42, 43, 43X, or 48 in any light. Unlike standard sights that disappear when the sun goes down, the DXW2 uses a large, high-contrast front dot that glows photoluminescently in low light before transitioning to tritium once it's truly dark. The design philosophy is straightforward: keep your focus on the front sight where it belongs, especially when you need it most. The yellow front dot absorbs ambient light aggressively, charging faster and brighter than other colors—critical when you're transitioning from daylight to indoor or dusk conditions. Paired with a low-profile white stripe rear sight, the contrast eliminates any chance of confusing front and rear in a high-stress moment.
The big dot itself measures 0.188 inches in outside diameter, large enough to acquire quickly while remaining narrow enough to fit standard holsters without modification. The matte black finish stays non-reflective and professional-looking on your carry gun. XS built these sights to be practical: the front sight uses both photoluminescent glow and tritium in one unit, so you get reliable visibility in twilight, darkness, and everything between. Installation requires a dovetail tool; note that some fitting may be necessary depending on your slide, and XS recommends against using a sight press tool.
Made in the USA, these sights are purpose-built for shooters who carry their Glock seriously and want sights that actually work when their eyes aren't young and the light is gone. Whether you shoot the compact .380 platform (42) or the slim 9mm (43, 43X, 48), the DXW2 system delivers the same proven sight picture and light-gathering performance.

The yellow front dot is photoluminescent—it absorbs and stores ambient light, then glows in low-light conditions before it's dark enough to see tritium. The tritium takes over in complete darkness. The white rear stripe is non-tritium, using only white paint, which helps maintain sight picture contrast and keeps focus on the front sight.
