The AmeriGlo Optic Compatible Sight Set for the Glock 43X and 48 Slimline A-Cut (AmeriGlo part no. AC-880) pairs a green tritium front sight with a plain black rear sight, both cut for a precise, elevated co-witness with a slide-mounted red dot. AmeriGlo built this Slimline version specifically for the narrower 43X and 48 single-stack slides, where a Standard Width set built for the Gen 5 line wouldn’t seat correctly. It uses a threadlock-prepped screw with a 16 in-lb torque spec for a secure, repeatable install.

Key Specifications

• Fits the Glock 43X and 48 Slimline A-Cut slide specifically, not the wider Gen 5 Standard Width slide.
• Front sight uses a green tritium insert with a black outline for reliable low-light aiming.
• The rear sight is plain black with no tritium, keeping cost down versus a full front-and-rear tritium set.
• Front blade measures .125 in. wide and .240 in. tall.
• A square notch rear, .150 in. wide, gives a precise co-witness sight picture.
• Torque specification of 16 in-lbs, with threadlock pre-applied to the mounting screw.
