The Glock Factory Barrel for the Glock 23 Gen4 in .40 S&W (brand part no. 39896) is a genuine Glock replacement barrel built to the same tolerances as the barrel that ships in a new Glock 23. Machined from black steel and cut to 4.49 inches, it is threaded at the muzzle for shooters who want to add a compensator or suppressor without sending the pistol out for aftermarket gunsmithing. Because it is a factory Glock part, fit and function match the original barrel exactly, making it a reliable choice for replacing a worn barrel or converting a stock Glock 23 to a threaded configuration. This barrel is a Title I part and does not require an FFL transfer on its own.
