The XS Sights DXT suppressor height night sight set brings fast, reliable target acquisition to a wide range of Glock pistols in any light condition. Purpose-built for defensive shooting and carry, these tritium night sights are engineered to get your rounds downrange when it matters most — whether you're training at the range, carrying for personal defense, or working in low-light environments. XS Sights precision-machines every set in Fort Worth, Texas, and the DXT's big dot design has earned a solid reputation among shooters who prioritize speed and clarity over traditional three-dot geometry.

The standout feature here is the big dot front sight. At 0.188 inches wide, it's substantially larger than conventional sight dots, which makes it easier to track in dim light and faster to align on target under stress. The white outline around the tritium dot works double duty: it catches ambient light during daytime shooting for excellent visibility, and the green tritium glows reliably when darkness falls. Pair that with the express rear sight — a shallow V-notch fitted with a vertical tritium stripe — and you get an unobstructed sight picture with a wide field of view, crucial when you're moving or engaging multiple targets. The setup is designed so you simply "dot the i" (place the front dot in the rear notch) and center it on your target; well-suited for combat-effective hits inside 15 yards.

Suppressor height is the key here. These sights sit tall enough to clear most suppressors and optic mounting systems, so you won't be forced to choose between night sights and accessories. The 0.188-inch outside diameter big dot fits common holsters without modification. One important note: installation may require filing to fit the dovetail properly on your specific Glock; XS strongly recommends against using a sight press or pusher tool.
