XS Sights DXT2 PRO Big Dot Night Sights – Glock 20/21, Green Tritium Front

The XS DXT2 PRO Big Dot sight set combines a high-visibility tritium front dot with a tactical rear sight designed for defensive and duty use on Glock 20 and 21 pistols. The oversized front dot provides fast target acquisition in daylight and low-light conditions, while the shallow V-notch rear with tritium bar enables quick alignment under stress. Green tritium front dot glows continuously for 10-12 years without batteries.

Constructed from machined steel with a corrosion-resistant finish, these sights install in standard Glock dovetails using a sight pusher or gunsmith tools. The rear sight features a ledge for one-handed slide racking. Designed for defensive shooting where speed matters more than precision bullseye accuracy—ideal for concealed carry, home defense, and law enforcement applications.
