The AmeriGlo 0.240-Inch x 0.125-Inch Green Sight for Glock (AmeriGlo part no. GL-112-240) is a tritium-illuminated sight insert sized to a 0.240-inch by 0.125-inch footprint, one of several width and height combinations AmeriGlo offers so shooters can match sight dimensions to their specific Glock generation and slide cut. The green tritium vial glows without any battery or light source, giving a consistent point of aim in both daylight and complete darkness, with a white outline ring around the tritium insert to help the eye pick up the dot faster in bright light. It’s a direct swap for a factory or worn sight using AmeriGlo’s standard mounting dimensions.
