The AmeriGlo 4L Optic-Compatible Sight Set (AmeriGlo part no. GL-456) is a front and rear iron sight set for Glock pistols that gives an elevated co-witness sight picture through a slide-mounted red dot. The front is a black serrated post .280 inch tall, and the rear is a flat black blade that stands .355 inch. AmeriGlo lists it as fitting all Glock models, including MOS slides. It also works as backup iron sights if the optic fails, and for use with a suppressor.
