The XS Sights DXT2 Big Dot night sights for Sig Sauer put a tritium-illuminated front sight in your line of sight—literally. Built around a large, round dot up front, these sights are engineered for the split-second decisions of self-defense shooting. The oversized front sight makes target acquisition instinctive in daylight; add the green tritium glow and the photoluminescent ring that charges in bright conditions, and you've got a sight picture that works when sunlight fades. This is purpose-built for defensive shooters and concealed-carry holders who need their gun ready in any light.
The rear sight strips away complexity with a simple vertical tritium stripe, creating a clean sight picture when you "dot the i"—the company's shorthand for aligning that prominent front dot with the rear notch. The shallow rear notch design opens up your field of view, keeping your eyes on threat and target rather than locked onto the sights themselves. That matters most inside 15 yards, where most gunfights happen. The sights are housed in a black steel construction and designed to fit all common holsters, though you may need to have a gunsmith fit them into your Sig's dovetail.
If you carry a Sig Sauer pistol for defense, duty, or backup, night sights remove the guesswork of locating your gun in low light. The DXT2 Big Dot is a no-frills answer to that problem—no lasers, no batteries, just proven tritium and photoluminescent engineering that's been tested by shooters and trainers for years.

Yes, the DXT2 Big Dot is designed for the Sig Sauer P365. The sights are built to fit all common holsters, but you may need to have a gunsmith file the dovetail for a proper fit.
The front and rear sights are filled with tritium, a radioactive isotope that glows continuously in the dark without needing batteries or external power. The photoluminescent ring around the front sight absorbs light during the day and releases that energy as a glow in darkness, giving you a fully lit sight picture in low-light and nighttime conditions.
The DXT2's large, round front sight is easier to acquire quickly than a thin post, especially under stress or in dim light. The shallow rear notch opens up your field of view so you stay focused on the target rather than the sights themselves. This design is optimized for defensive shooting inside 15 yards, where speed beats precision.
Yes. The large front dot and simple rear notch align easily in bright sun. The tritium is always present, but daylight is so bright it overwhelms the glow—the photoluminescent ring charges during daylight so the sights glow as soon as you move into lower light.
