The XS Sights DXW2 Big Dot Sight (part no. GL-0011P-3Y) fits the Glock 42, 43, 43X, and 48, giving those slim single-stack carry guns a single, fast-acquiring yellow Big Dot front instead of a standard three-dot picture. The DXW2 rear is a low-profile V design with a non-tritium white stripe, built to get out of the way and let the tritium front do the work in a defensive shooting.

Key Specifications

• Front sight is tritium-powered for round-the-clock illumination.
