AmeriGlo GL806 Features The AmeriGlo 3 Dot Square Notch Rear Sight Set uses green tritium inserts front and rear to glow continuously in low light giving the shooter a usable sight picture long after ambient light fades. The front sight carries a black outline around its green tritium vial which adds contrast against a variety of backgrounds and speeds up visual acquisition during a fast presentation from the holster. The square notch rear sight is cut to create a clean uniform gap around the front sight helping the eye align the dots quickly and consistently under stress. This three dot configuration is a time-tested design trusted by countless concealed carriers and duty shooters alike. Built specifically to fit the Glock 42 43 43X and 48 pistols this sight set is sized correctly for these slimline and subcompact frames without any additional fitting. The Black frame finish is durable enough to withstand repeated holster draws and daily carry wear without losing its sharp sight picture. Upgrading factory sights to a tritium set like this one is one of the most practical improvements a concealed carrier can make to their everyday carry pistol. For Glock owners who carry in dim parking lots hallways or low light rooms the AmeriGlo 3 Dot Square Notch Rear Sight Set delivers the reliable night visibility factory sights lack.
