XS Sights DXT2 Big Dot night sights bring reliable, fast target acquisition to your Smith & Wesson pistol in any light. Designed with the defensive shooter in mind—whether you carry for work, protection, or competition—these tritium night sights combine a bold front sight dot with a clean, functional rear to help you get on target quickly when it matters. The green tritium tubes glow without batteries; the yellow outline on the front and white outline on the rear catch light and your eye in daylight, then transition seamlessly to self-illuminated night shooting. If you've ever struggled to see your sights in a dark hallway or dimly lit range, the DXT2's larger-than-standard dot design addresses exactly that problem.
The heart of the DXT2 system is the big dot front sight—0.188 inches of sight picture. The convex shape absorbs ambient light and converts it to a soft glow in low-light conditions, while the photoluminescent material adds extra visibility when external light is scarce. During development, XS Sights found that the yellow outline variant glows brighter in darkness, making it the go-to choice for shooters who prioritize low-light work. The rear sight features a shallow V-notch and a low-profile ledge, giving you an unobstructed view of your front sight while also serving as a tool for one-handed slide manipulation—a useful feature in defensive scenarios.
Built from CNC-machined steel, these sights are tough enough for daily carry, training, and duty use. The tritium inserts are backed by a 12-year warranty, so you're covered for the service life of your gun. Installation requires gunsmithing or the right tools and knowledge; if you're not comfortable drifting sights yourself, have a qualified armorer handle it to ensure proper fitment and zero.

No. The tritium tubes are self-illuminating and require no batteries, charging, or external power. They glow continuously for approximately 12 years, after which the tritium decays naturally.
Yes. The yellow outline on the front sight and white outline on the rear sight are highly visible in daylight conditions. The tritium glows all the time, but bright outlines ensure fast sight acquisition in any light.
XS Sights testing found that the yellow outline variant glows brighter in low-light and nighttime environments compared to other colors, making it ideal for defensive and duty use where low-light performance is a priority.
