XS Sights DXT2 Suppressor Height Night Sight Set for Glock 17-36, Big Dot Tritium Front & Tritium Stripe Rear

The XS Sights DXT2 Suppressor Height Night Sight Set for Glock 17–36 puts the front sight front and center—literally. Built around a large, high-contrast Big Dot front paired with a low-profile V-notch rear, these tritium night sights are engineered to keep your focus where it matters in a fight: on the front post. The suppressor-height design clears most slide-mounted red dots and co-witnesses with factory Glock cuts and RMR footprints, making them a natural fit if you're running optics or planning to add them later.

The DXT2's real strength is visibility across the spectrum. The front sight features a patent-pending glow dot that absorbs ambient light and glows in low-light conditions before transitioning to tritium once the sun's down. In bright daylight, the Optic Orange color (a yellow base with a hint of red) cuts through glare with high contrast; as light fades, that glow function kicks in to bridge the gap. The oversized convex dot increases light absorption, intensifying the charging effect. You get a clean, unambiguous sight picture—tritium dot up front, tritium stripe in the rear—that leaves no room for confusion when adrenaline is running high.

The 0.188-inch outer diameter Big Dot is large enough to acquire quickly but small enough to fit common holsters without modification. Installation is straightforward on most Glocks; some Walther models may require minor dovetail fitting. These sights are compatible with Glock 17, 19, 22, 23, 24, 26, 27, 31, 32, 33, 34, 35, and 36, plus Taurus G3c, GX4, and newer G3 models, and Walther PDP and current CCP M2 variants.

Whether you're training for defensive carry, running night courses, or simply want a sight system that works across dawn to dusk, the DXT2 Suppressor Height set delivers the kind of front-sight-focused design that turns good shooters into reliable ones.

Frequently Asked Questions

Will these suppressor-height sights work with my optic?

Yes. The DXT2 Suppressor Height set achieves a lower-third co-witness with Glock factory-cut slides and RMR-compatible footprints. This means if you're running a red dot now or planning to add one, these sights will sit at the correct height to appear in the lower portion of the optic's window.

What Glock models do these sights fit?

The DXT2 set fits Glock models 17, 19, 22, 23, 24, 26, 27, 31, 32, 33, 34, 35, and 36. They're also compatible with Taurus G3c, GX4, and new production G3 pistols, and Walther PDP and current CCP M2 models. Some Walther models may require minor dovetail fitting during installation.

How do the glow and tritium work together?

The front sight's glow dot absorbs ambient light and glows visibly in low light before conditions get dark enough to rely on tritium alone. As daylight fades, you transition seamlessly from the bright Optic Orange dot to the glow function, then to tritium once it's fully dark. This layered approach keeps the front sight visible across the entire light spectrum.

Will these fit in my holster?

The 0.188-inch outer diameter of the Big Dot front sight is designed to fit standard holsters without modification. However, fit can vary by holster design, so test before relying on it for carry.
