Silencerco Ac5335 9Mm 1/2"X28 416R S/S Black

A quality threaded pistol barrel is the foundation of any suppressed 9mm pistol, and the SilencerCo AC5335 9mm barrel is purpose-built for that job. This 416R stainless steel barrel is engineered to handle the pressures and longevity demands of suppressed shooting, with a 1/2"×28 thread pitch that accommodates SilencerCo suppressors and other compatible cans on the market. If you're running a Gen 5 GLOCK 17 and serious about quiet, accurate shooting—whether for home defense, range work, or training—a quality aftermarket barrel paired with a suppressor makes a measurable difference in reliability and shooter experience.

SilencerCo didn't just slap threads on a barrel and call it done. These barrels are built to the same quality standard as their suppressors: 416R stainless steel with a black nitride finish that resists corrosion and wear. That means your investment holds up through thousands of rounds, whether you're running subsonic loads or standard ammunition. The fit and finish reflect the attention to detail you'd expect from a suppressor manufacturer—because they understand that the barrel is part of the system.

Installing a threaded barrel transforms your pistol from hearing-damage territory into genuine hearing-safe territory when paired with a quality suppressor. It's one of the smartest upgrades for shooters who want to preserve hearing, reduce environmental noise, and shoot more comfortably and accurately. If you own a Gen 5 GLOCK 17 and are serious about suppressed shooting, this barrel is a straightforward, reliable choice.
