The JK Armament 155 VersaX 9K is a modular 9mm suppressor that you can set up to fit the job. Run it as short as 3.3" and about 3.7 oz on a pistol, or build it out to the full 7.3" stack (about 8.5 oz) for maximum quiet on a pistol-caliber carbine. A tone tuner is included so you can shape the sound.
It's 7075 billet aluminum with a Type III hard anodized finish. It's rated for full-auto in 9mm, .38 Special and .357 Magnum, with no minimum barrel length on those pistol calibers.
JK has retired the VersaX 9K, so this is limited stock. Grab it while we have it.

Compatibility
The VersaX ships with JK's LT quick-attach taper mount but no muzzle device, so you'll need a matching JK taper muzzle device for your barrel. Prefer direct thread? JK 155 HD thread mounts thread into the same HUB socket, like our 155 HD mount in 11/16x24. Any 1.375x24 HUB booster also fits for running it on a tilting-barrel pistol.
