This Night Fision tritium night sight set for the Glock 42, 43 and 43X is a drop-in upgrade for the small single-stack Glocks (Night Fision part no. GLK-003-003-YGZG). Night Fision molds its own sleeve to hold the tritium vial, which the maker says carries more tritium than the average night sight. A domed lens focuses the glow into a crisp dot, so the sights stay usable as your eyes adjust to the dark. The sights stand at Glock OEM height, which keeps your sight picture familiar. They are made for concealed carry owners who want a sight that works day or night.

Key Specifications
