Running a suppressor on your HK VP9? You'll need the SilencerCo AC1549 threaded barrel for H&K VP9 — a precision replacement barrel that converts your 9mm VP9 to accept a suppressor or other muzzle devices. SilencerCo engineered this barrel to factory specifications, so it fits and functions like the original, just with the muzzle threading you need to mount modern sound suppressors, muzzle brakes, or compensators.
The barrel is machined from 416R stainless steel and fitted with 1/2x28 threads, the standard pitch for most 9mm pistol suppressors on the market today. It's built to work with the standard 4.5-inch barrel 9mm VP9 and features 1-in-10-inch right-hand rifling that matches the VP9's twist rate. Drop it in, and you're ready to run a can or other threaded muzzle gear without modification to the slide or frame.
If you're serious about suppressor shooting with your VP9 — whether for reduced signature at the range, hearing protection during training, or just quieter practice — a dedicated threaded barrel beats trying to adapt the factory tube. SilencerCo's precision engineering means zero guesswork about fit or reliability.
