XS Sights
The XS Sights DXT2 Big Dot night sight set for S&W M&P Full Size and Compact handguns is purpose-built for shooters who need to move fast in low light. Self-defense and home-defense scenarios often happen when ambient light is lowest—inside buildings, at dawn, at dusk—and that's where tritium-illuminated sights earn their weight. This set pairs a large, round tritium front sight with XS's signature rear stripe design, both glowing without batteries. The front sight adds a photoluminescent ring, too, which picks up ambient light during transitions from bright to dim environments, giving you an aiming reference whether the lights are on or off.
The "dot the i" aiming method—lining up the round front sight in the rear notch—is faster and more instinctive than aligning three dots or thin post-and-aperture combos, especially under stress. XS designed this set for rapid engagement at typical self-defense distances, inside 15 yards, where speed matters more than precision at distance. The shallow rear notch gives you a wider field of view, reducing the tunnel vision that can creep in during high-stress moments. These sights fit all common holsters, though you may need to fit them to your slide's dovetail with a small amount of filing.
Compatibility is straightforward: this set is engineered for S&W M&P double-stack handguns in full-size and compact frames, as well as the SD-VE platform. If you carry or train with your M&P as a defensive tool and spend time shooting in variable light, night sights aren't a luxury—they're a practical upgrade that keeps your sight picture intact long after your flashlight battery dies.
| Brand | XS Sights | |
| Model | DXT2 Big Dot | |
| Sight Type | Night sights (tritium + photoluminescent) | |
| Front Sight | Round tritium with photoluminescent ring | |
| Rear Sight | Tritium-illuminated vertical stripe | |
| Compatible Firearms | Smith & Wesson M&P Full Size, M&P Compact, SD-VE | |
| Rear Notch Style | Shallow (wide field of view) | |
| Intended Use | Self-defense, home defense, rapid shooting inside 15 yards |
Yes—this set is designed for S&W M&P double-stack handguns in full-size and compact frames, as well as the SD-VE platform. Installation may require minor filing to fit your slide's dovetail. The sights fit standard holsters.
Tritium is a radioactive isotope sealed inside glass vials that continuously produces a faint green glow without any external power source. The light is always on, though subtle—just bright enough to form a sight picture in darkness. The photoluminescent ring on the front sight absorbs ambient light during the day and early evening, providing an additional aiming reference during light-to-dark transitions.
With the DXT2, you align the round front sight inside the rear notch, similar to dotting the letter "i." This method is faster and more intuitive under stress than aligning three dots or thin post-and-aperture combinations, especially at typical defensive distances inside 15 yards.
No—the DXT2 set is purpose-built for rapid engagement at close defensive distances, typically inside 15 yards. The big dot front sight prioritizes speed and instinctive aiming over the precision required for longer-range or target work.
