Having the right sights on your small, compact handgun can make the difference in a fight, and the XS Sights DXT2 Big Dot night sights are built right to encourage the front-sight focus needed to get fast, accurate rounds on target when it counts, even in low-light or nighttime conditions. Each pair of XS Sights DXT2 Big Dot night sights are built with a tritium-illuminated, round front sight that allow for fast targeting in the dark, while a photoluminescent ring around the tritium lamp also allows for easy aiming when moving from bright to dark environments. The front sight is combined with the company's rear-sight design that incorporates a vertical, tritium-illuminated stripe. When it comes to aiming, getting your gun on target is fast and instinctive: just dot the i! The XS Sights DXT2 Big Dot night sights are constructed with a shallow rear notch for a greater field of view, and the sight is designed for rapid aiming at targets inside of 15 yards. This particular pair of DXT sights are sized right for the Glock®G42 and G43. The sights fit all common holsters and may require filing to fit into the dovetail.
