The XS Sights DXT2 Big Dot tritium night sight set brings a defensive-focused aiming system to your Glock 17, 19, 22, 24, 26, 27, 31, 36, or 38. Built around the principle that defensive shooting demands speed over precision, these night sights use a large, glowing tritium dot up front paired with a vertical tritium stripe in back—a combination designed to get you on target intuitively at the ranges where it matters most. The "dot the i" aiming method is intuitive enough to work under stress, and the tritium illumination means you're not guessing in low light.
The front sight features a round tritium lamp with a photoluminescent ring around it, letting you transition smoothly from daylight to darkness without losing your sight picture. The rear sight's shallow notch gives you a wider field of view, which speeds target acquisition and keeps you aware of your surroundings—critical in a defensive scenario. These sights are engineered for close-quarters work; they shine at defensive distances inside 15 yards where most defensive handgun encounters occur.
Compatibility spans the most common Glock double-stack models, so whether you're carrying a 17, carry a compact 26, or shoot a .40 variant, there's a DXT2 set for your gun. Note that some fitting may be required during installation to match your specific dovetail, and the sights are designed to work with common holster configurations.
