This GSX 23X uses a genuine Glock 23 slide with rear cocking serrations and a durable matte-black nDLC finish. The 4.02-inch carbon-steel barrel is treated with the same finish for corrosion resistance and easy cleaning.
The hybrid GSX frame deletes the original finger grooves and adds aggressive wrap-around stippling, giving shooters a secure grip while accepting all Gen 3 Glock internal components. An extended magazine catch and extended slide-lock lever come installed for faster, more positive manipulation.
Pairing the compact slide with a full-size grip lets the pistol cycle quickly while accommodating Glock 22/35 pattern magazines up to 22 rounds. Standard Glock white-dot front and white-outline rear sights provide a familiar sight picture right out of the box.
Built with glass-fiber-reinforced polymer rails and a striker-fired action, the GSX 23X maintains the proven reliability of the Glock system while adding capacity and ergonomic improvements that matter on the range or in defensive roles.
