Glock 23 Threaded Barrel

Factory G23 Threaded Barrel

This is a Glock-made threaded barrel for the Glock 23, the compact .40 S&W pistol. It replaces the standard barrel so the muzzle extends past the slide with exposed threads for a suppressor, compensator or other muzzle device. It suits G23 owners who want to add a muzzle device while keeping a factory part in the gun.

Features

• Genuine Glock Part — Made by Glock for the Glock 23, so it matches the pistol's original barrel dimensions.
• Chambered In .40 S&W — Matches the Glock 23's factory caliber, so you keep using the same ammunition and magazines.
• Threaded Muzzle — The barrel is cut with external threads at the muzzle, which is where a suppressor or compensator screws on.
• Extended Length — The barrel runs longer than standard so the threaded section sits clear of the slide.
• Knurled Thread Protector — A screw-on cap with a grooved grip covers the threads when no muzzle device is fitted.
• Black Finish — The barrel, hood and thread protector have a uniform dark finish, as the photographs show.
• Marked Barrel Hood — The hood, the squared block at the chamber end, carries Glock's factory markings and serial number.

Fit And Setup Notes

The barrel is built to replace the factory barrel in a Glock 23 and uses the pistol's existing slide, recoil spring and frame. Before you buy a muzzle device, confirm that its thread pitch matches this barrel. Glock pistols have a tilting barrel, so most suppressors on a G23 need a booster, a recoil-assist piston inside the suppressor, to cycle reliably. Many owners also fit taller sights so they can see over the suppressor body.
