Description
This is the genuine factory replacement threaded barrel for the HK VP9, made right here in Germany using cold hammer-forged steel and precision engineering. If you've got a standard VP9 and want to run suppressors, compensators, or other muzzle devices, this is the official HK solution.
The barrel measures about 4.45 inches overall and features a 1-in-9.8 right-hand twist with HK's polygonal rifling profile. You get a micro-polished feed ramp that keeps everything running smooth, and the barrel is finished in matte black to match your slide. Installation is straightforward on compatible pistols, dropping right into place without any gunsmithing or fitting.
H&K VP9 Threaded Barrel Thread Design
This barrel uses M13.5×1 left-hand metric threads rather than the common 1/2×28 standard. That matters because left-hand threads reduce the chance of muzzle devices loosening during recoil, which is why HK chose them in the first place. The left-hand design is standard on European firearms and works perfectly with metric-threaded suppressors and compensators built to this specification.
Drop-in Installation and Compatibility
The barrel is designed as a direct replacement for full-size VP9 platforms and installs without any modification to your pistol. It's machined to exact HK German tolerances, so you get that factory precision fit every time. This is the OEM part, so you're getting the same barrel HK uses on their VP9 Tactical models.

Frequently Asked Questions
Does the H&K VP9 threaded barrel come with a thread protector?
No, the barrel does not include a thread protector. It's sold separately. We recommend getting one to protect the threads when you're not using a muzzle device or suppressor, especially during storage and transport.
Will this VP9 threaded barrel fit my VP9 Compact or VP9 Match?
This barrel is designed for full-size VP9 models only. It will not fit VP9 Compact or VP9 Match variants. If you have a compact or match model, you'll need the barrel made specifically for that version.
What muzzle devices work with the M13.5×1 LH threads?
You can use any suppressor or compensator made for metric M13.5×1 left-hand threads. Many European-made devices and some American manufacturers offer options for this thread pitch. Verify compatibility with your specific muzzle device before purchase, and remember that thread adapters are available if you want to use devices with different thread patterns.
Can I install this barrel myself?
The barrel drops in without fitting or gunsmithing on compatible VP9 frames, making installation straightforward. However, HK recommends having their parts installed by a qualified gunsmith to ensure proper function and safety.
