The XS DXT2 Big Dot is one of those upgrades you notice the second you pick the gun up. Instead of a thin, hard-to-see factory post, you get a large front dot ringed in photoluminescent yellow with a tritium vial in the center. That yellow charges off ambient light and stays lit as things dim, then the tritium takes over once it's fully dark. In practice it means your front sight is easy to find in bright sun, at dusk, or in a pitch-black room, and it's tuned specifically for the S&W M&P Full Size and Compact Optic Ready platform.
XS built these around what they call a dot-the-i sight picture. You've got a round tritium dot up front and a vertical tritium bar in the shallow V-notch rear, so under stress your eye stacks the dot on top of the bar without second-guessing which sight is which. The rear is intentionally low-profile with a wide, open V so it doesn't clutter your view of the front dot or the threat downrange. The convex shape of the front dot gives it more surface area than a flat sight, which helps it soak up more light and glow brighter.
These are CNC machined from solid steel bar stock, so they hold up to the daily grind of a carry gun. The 0.188 inch front dot is sized to still clear common M&P holsters, and the standard height keeps you working with the same holster you already run. This set is cut for the M&P Full Size and Compact Optic Ready models, so double-check your slide before ordering to make sure you've got the matching cut.
XS designed the DXT2 to go in with a hammer and brass punch rather than a sight press, and they specifically recommend against using a pusher tool. Factory M&P front sights can be stubborn to drive out, and some fitting or light filing to the dovetail is normal with a set like this. If you're comfortable with basic sight work you can knock it out at the bench, otherwise a gunsmith will have it dialed in quickly. Written install instructions are available from XS to walk you through it.
This set is cut specifically for the S&W M&P Full Size and Compact Optic Ready models. Before ordering, verify your slide's sight cut matches, since the M&P family has several variations. If your gun is an Optic Ready full-size or compact, you're in the right place.
Both. The yellow glow ring charges off ambient light and stays visible as the light fades, then the tritium vials keep the front and rear lit in total darkness. That combination gives you a usable sight picture around the clock without needing batteries.
XS recommends installing with a hammer and brass punch rather than a sight pusher tool. Factory M&P front sights can be tight to drive out, and some minor filing to fit the dovetail is common with these. If you're not comfortable doing sight work yourself, a gunsmith can install them quickly.
The oversized front dot is designed to grab your eye fast, which is a real help for aging eyes or high-stress, close-range shooting. Paired with the dot-the-i rear bar, it keeps your focus locked on the front sight without confusing the two. It's a defensive-minded setup built for speed over precision target work.
