The XS Sights DXT2 Big Dot night sights for Sig Sauer and Springfield Armory pistols are purpose-built for shooters who need reliable sight acquisition from low light to full dark. The DXT2 system pairs a high-visibility front sight with a supporting rear notch to keep your focus where it matters most—on the front sight. Whether you're running night shifts, working in shadows, or training after sunset, the green tritium in both front and rear gives you a constant aiming reference without batteries or external light sources.
The front sight's big dot design combines photoluminescent material with tritium to handle the full spectrum of lighting. In twilight or dim indoor conditions, the glow dot absorbs ambient light and emits a visible glow before it's dark enough for tritium to dominate. The orange/yellow front contrasts sharply against the rear white outline, creating a natural sight picture that your eyes find instantly even under stress. The wide field of view around the front sight keeps your target and surroundings in peripheral focus while your aiming eye locks on the dot.
The V-notch rear sight is intentionally unobstructed so nothing competes for your attention. That design pays dividends in carbine transitions, one-handed shooting, or any scenario where seconds and clarity matter. The rear white outline provides just enough definition to align with the dominant front dot—you're not split between competing visual anchors. Tritium fills both sights, so performance remains consistent whether you're checking zero at the range in daylight or deploying when the sun's down.

The green tritium in both front and rear sights glows continuously without any external light source, providing a visible aiming reference in complete darkness. The photoluminescent material also absorbs and stores light energy, emitting a glow in low-light conditions before tritium becomes the dominant light source.
The high-contrast orange front sight with yellow outline captures your focus and is easier to acquire quickly. The white outline on the rear sight provides definition without competing for your attention—the design keeps your aiming eye anchored on the bright front dot.
Yes. The orange front and white rear outlines provide a clear, high-contrast sight picture in daylight. The tritium becomes more prominent as ambient light decreases, making these sights effective across all lighting conditions.
