The XS Sights DXT2 Big Dot is built around one simple idea: your eye should find the front sight without thinking about it. That big convex orange dot up front does exactly that, driving your focus to the point of aim while a shallow V-notch rear stays out of the way and keeps your field of view wide open. It's a front-focused setup that shines when speed matters, and it's a favorite for everyday carry and duty use on Glock pistols.
The front sight combines a tritium vial with a photoluminescent Glow Dot that soaks up ambient light and glows in that in-between dusk period before it's dark enough for the tritium to take over. The orange color is the pick for daylight contrast, giving you a high-visibility front sight against busy backgrounds, while still glowing brighter than plain tritium as the light drops. XS uses a "dot-the-i" sight picture here, meaning a dot in front and a bar in the rear, so you never confuse the two when your heart rate is up.
These are CNC machined from steel bar stock, not plastic, so they hold up to drops, hard holster wear, and years of range time. The convex dot has no sharp edges to snag on clothing during a draw from concealment, and it wipes clean of powder residue with a cloth. XS also builds these to a suppressor height, which raises them tall enough to clear most cans and to co-witness with a red dot optic on MOS slides.
This set covers a wide swath of the Glock lineup, including the 17, 19, 22, 23, 24, 26, 27, and 31, with the standard front Big Dot measuring 0.188 inches wide. If you run an optic-ready MOS pistol, the suppressor height gives you a lower 1/3 co-witness with popular optics like the Trijicon RMR and Holosun 507C. Installation is straightforward with a punch and hammer or a sight pusher, and plenty of shops will drift them in for you.
Yes. Because these are suppressor height, they sit tall enough to give you a lower 1/3 co-witness on optic-ready MOS slides. That works with popular optics like the Trijicon RMR and Holosun 507C, so you keep a backup iron reference in the window without crowding it.
Orange gives you the best contrast in bright daylight against varied backgrounds, which makes the front sight jump out fast. It still glows in low light thanks to the photoluminescent dot and tritium, though the yellow version glows a touch brighter after dark. If your priority is daytime visibility, orange is the way to go.
Most people find them straightforward. You can drift them in with a punch and hammer or use a sight pusher, and there are install videos on the XS site. Factory sights can be tight to remove, so if you'd rather not fuss with it, plenty of shops will press them in for you.
This set covers a wide range including the Glock 17, 19, 22, 23, 24, 26, 27, and 31, including MOS versions. The subcompact 42/43/48 family uses a different XS set, so double-check your exact model. If you're unsure, the frame size and generation determine the right fitment.
