The AmeriGlo Classic Rear Sight (AmeriGlo part no. GL-404) is a black notch rear sight built to fit the full lineup of standard Glock pistols. It uses AmeriGlo’s classic notch profile rather than a tritium or fiber-optic insert, giving you a simple, low-glare rear reference that will not wash out or wear down like a painted dot. Shooters who prefer a plain black rear sight paired with a bright or tritium front use this to clean up their sight picture without spending extra on a rear tritium vial. It is a straightforward, drop-in replacement for the factory Glock rear sight.
