Glock 23 9mm threaded conversion barrel — drops into a Glock 23 Gen 3 slide and converts the pistol from .40 S&W to 9mm Luger using a 9mm magazine. The 1/2x28 threaded muzzle accepts common 9mm compensators, thread protectors, and pistol-caliber suppressors built to that pitch.
Machined from 4150 chrome moly vanadium steel and finished in black nitride for hardness, corrosion resistance, and a matte look that pairs cleanly with stock or aftermarket Glock 23 Gen 3 slides. Chamber and bore are cut to 9mm spec — feed 9mm range or defensive ammunition from a 9mm magazine in your existing Glock 23 frame.
Specs:
Magazine note: A 9mm magazine is required for feeding. The .40 S&W magazine that ships with a factory G23 will not reliably feed 9mm rounds. G17, G19, or G26 9mm mags work depending on capacity and pistol grip length.
Micro Comp pairing: The 1/2x28 pitch mates with the 3CR 9mm Micro Compensator for a clean muzzle package on a G23 conversion build. Run 50–100 rounds for break-in before adding a comp or suppressor.
