The G23 Gen4 delivers the compact frame size counterpart to the G19 in .40 S&W, pairing carry-friendly dimensions with a 13+1 capacity and a 4.02" barrel. It retains Glock's fixed polymer sights with a white dot front and rear-only slide serrations for straightforward operation.
Gen4 updates include a reversible, enlarged magazine release and a dual recoil spring assembly that refines cycling characteristics. The frame is MBS-ready, allowing setup changes when using Glock’s modular backstrap system components.
The dustcover features a single-slot accessory rail for mounting compatible lights or other add-ons. Controls are simple and durable, with the familiar Glock trigger safety integrated into the Safe Action, striker-fired, short-recoil, locked-breech system.
This pistol has an aftermarket grip overlay with a stipple-style texture applied to the sides and backstrap for added traction. It also carries matching serial numbers on the slide, barrel, and frame, with markings that include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." and an AT mark on the chamber.
Construction is classic Glock: a polymer frame paired with a steel barrel, fixed polymer sights, and clean, functional lines. The included trio of factory 13-round magazines supports the platform’s standard capacity.
