- Oversized convex Big Dot front sight maximizes light absorption and target acquisition speed
- Optic Yellow finish offers the brightest photoluminescent glow intensity available
- Patent-pending glow dot activates in low light before tritium becomes necessary
- V-notch rear sight channels focus directly to the front dot for intuitive alignment
- Tritium vial provides 10+ years of reliable glow in true darkness
- Designed specifically for Glock 17, 19, and 22 with a direct drop-in fit
Who This Is For
The DXT2 Big Dot Night Sights are purpose-built for concealed carriers, home defenders, and law enforcement professionals who need a fast, instinctive sight picture under any lighting condition. If you draw from concealment and need to put rounds on target quickly — in a dimly lit parking garage, a shadowy hallway, or full daylight — the Big Dot's high-contrast, wide-angle design minimizes target-to-sight transitions and gets you on point faster than traditional three-dot systems.

Frequently Asked Questions
How does the Optic Yellow color improve low-light performance over white or orange?
Optic Yellow is primarily based on the white light spectrum, making it highly reflective and able to excite the photoluminescent properties of the dot faster than any other color. This means the sight begins glowing brightly in low-light conditions well before it's dark enough to need the tritium vial — giving you an effective, visible front sight across the widest possible range of lighting scenarios, from dusk to deep shadow.
Will these sights fit all generations of the Glock 17, 19, and 22?
Yes. XS Sights DXT2 Big Dot Night Sights are compatible with Glock 17, 19, and 22 across Gen 1 through Gen 5, as all generations share the same standard dovetail sight cut. No modification to the slide is required, though a sight pusher tool or professional installation is recommended for a secure, properly torqued fit.
What is the difference between the Big Dot and a standard night sight front post?
A standard night sight typically uses a small, flat tritium dot or post that requires deliberate alignment with the rear sight. The XS DXT2 Big Dot uses an oversized, convex photoluminescent and tritium dot that draws the eye instantly to the front sight, allowing for a faster, more intuitive point-of-aim — especially under stress or in dynamic defensive situations where fine sight alignment isn't always possible.
