AmeriGlo Agent 3 Dot Tritium Night Sight Set for Glock 42/43/43X/48

Tritium sights glow on their own: a sealed vial of gas, no batteries and no charging under a flashlight. The Agent set puts a tritium lamp in the front sight and one on each side of the rear notch, so the picture you get in the dark is the same three dot arrangement you already use in daylight.

This set covers the slim Glock pistols: the 42, 43, 43X and 48. Those guns get carried hard, and the sights they leave the plant with are polymer, so a metal set with tritium is one of the first changes most owners make. Installation calls for a sight pusher at the rear and a front sight tool, both of which a competent gunsmith has on the bench.
