Small Glocks like the 42, 43, 43X, and 48 make great carry guns, but their factory sights can leave your eye hunting for the front post when it counts. The XS DXT2 Big Dot fixes that with an oversized front dot your eye locks onto without thinking. The whole idea here is speed: a big, bright front sight paired with a shallow V-notch rear that stays out of the way so you can see your target clearly downrange.
The front sight uses a convex photoluminescent Glow Dot in Optic Orange that soaks up ambient light and keeps glowing as things get dark, bridging that gap before it's dim enough for the tritium to take over. Orange gives you excellent contrast against most backgrounds in bright daylight, so it pops whether you're on a sunny range or moving through shadows. At the center of that dot sits a tritium vial, and the rear V-notch carries a tritium bar with a white outline, giving you a clean dot-the-i alignment that's hard to confuse under stress. Line the front dot up over the vertical rear bar and press.
XS machines these from steel bar stock in Fort Worth, so they hold up to drops, hard slide racks off barricades, and years of carry. The front dot measures 0.188 inches across, which is generous for visibility yet still slides into most holsters made for these Glocks. The edges are rounded and snag-free, so nothing hangs up when you draw from concealment.
Installation is straightforward for anyone comfortable with a punch and a little patience, and XS includes the front sight tool, thread locker, and hex key you'll need to get it done. These sights fit the Glock 42, 43, 43X, and 48. If your eyes aren't what they used to be, or you just want the fastest front sight in any light, the DXT2 Big Dot is one of the more proven upgrades out there and it's backed by a no-questions night sight warranty.
Yes, this set is cut specifically for the Glock 42, 43, 43X, and 48 slides. It replaces both your factory front and rear sights. Just make sure you're matching the right sight set to your exact model since XS makes different cuts for the larger Glock frames.
Both use the same Glow Dot technology, but Optic Orange gives you better contrast against varied backgrounds in bright daylight, while Yellow charges faster and glows the brightest in low light. This SKU is the Orange version. Eyesight varies from person to person, so some folks just see one color better than the other.
Most people can handle it with basic tools and some patience. The set comes with the front sight tool, thread locker, and a hex key, though you'll want a proper sight pusher or punch for the rear dovetail. If you're not comfortable working on your slide, any gunsmith can knock it out quickly.
It does. While the 0.188-inch front dot is larger than a stock sight, it's designed to clear most holsters made for these compact Glocks. The rounded, snag-free profile also keeps it from catching on clothing during the draw.
