XS Big Dot Tritium Night Sight System
Designed specifically for defensive use, the XS Big Dot Tritium front sight transforms your revolver into a low-light capable defensive tool. This sight system combines proven tritium technology with XS Sights' proprietary photoluminescent Glow Dot for performance in any lighting condition.
How It Works
The Big Dot's convex design provides significantly more surface area than traditional sight dots. This larger geometry absorbs more ambient light and intensifies the charge of the Glow Dot, ensuring visibility whether you're shooting in bright daylight or complete darkness.
