SilencerCo
Adding a suppressor to your Smith & Wesson M&P 9mm doesn't mean replacing the entire gun—the SilencerCo AC2023 threaded barrel for M&P 9mm does the heavy lifting with a factory-compatible drop-in swap. This replacement barrel threads your standard M&P for suppressor use, turning your centerfire pistol into a hearing-friendly range tool or hunting handgun without any gunsmithing. Built from high-grade stainless steel to original factory dimensions, it slides in like the part it replaces—no fitting, no guesswork.
The 1/2x28 threads are the industry standard for 9mm suppressors, so you'll have zero compatibility headaches pairing it with nearly any modern silencer in its class. The rifling is a 1-in-10-inch right-hand twist, spec'd to handle full-power 9x19mm loads reliably. Whether you're setting up for subsonic shooting, reducing noise at the range, or building a versatile home defense gun that won't ring your ears, this barrel gets you 90% of the way there—the other 10% is choosing your suppressor.
Important: this barrel fits full-size M&P 9mm pistols only and is not compatible with the 5-inch Pro Series. Confirm your model before ordering. Once installed, you'll have a suppressor-ready handgun that looks and functions like factory spec, minus the sonic signature.
