AmeriGlo 4XL Tritium Night Sight Set for Glock, Green/Black

The AmeriGlo 4XL Tritium Night Sight Set for Glock in green front/black rear (AmeriGlo part no. GL-824) gives Glock owners an elevated iron sight picture that co-witnesses with slide-mounted miniature red dot optics and suppressors. AmeriGlo has spent years refining tritium sight sets for duty, concealed carry, and range use, and the 4XL height solves the common problem of irons disappearing behind a taller optic or can. The front post measures 0.385″ high and the rear 0.480″ high, tall enough to bring both sights into the same plane as most red dot windows. Green tritium up front stays visible day and night, while the flat black rear keeps the picture uncluttered for a fast sight alignment.
