Walther Arms PPQ Q5 Match 5.50" Threaded Barrel - Black (Model 2835231)

The Walther Arms PPQ Q5 Match 5.50" threaded barrel is a drop-in replacement barrel built for shooters who want to run a suppressor or compensator on their Q5 Match steel frame pistol. If you're running a 1/2x28 suppressor or muzzle device—the standard thread pitch for 9mm competition and duty pistols—this barrel gives you a direct swap that maintains the reliability and precision your match gun demands. It ships with a recoil spring engineered to work smoothly with suppressor back-pressure, so you get consistent cycling whether you're running suppressed or open.

This is purpose-built for competitors and shooters who've settled on the Q5 Match platform and want the flexibility to add a can or comp without gunsmithing. The threaded design is optimized for the 1/2x28 standard, so compatibility with quality aftermarket suppressors and muzzle devices is straightforward. It's a no-fuss upgrade that respects the precision tuning your match gun already has.

The black finish matches the standard Q5 Match aesthetic and handles the wear and corrosion that comes with regular use. If suppressed shooting or compensator use is part of your match routine or home-defense setup, this barrel removes the guesswork from the install—drop it in, reassemble, and go to work.

Frequently Asked Questions

Will this threaded barrel work with my PPQ Q5 Match?

Yes—this is a drop-in replacement barrel designed specifically for the PPQ Q5 Match steel frame pistol. Unthread the stock barrel, install this one, swap in the included recoil spring, and reassemble.

What suppressor or compensator can I use?

Any suppressor or compensator with a 1/2x28 thread pitch will fit. That's the standard 9mm thread size, so you have a wide selection of quality options from most major manufacturers.

Does it come with everything I need to install it?

The barrel comes with a recoil spring tuned for suppressed shooting. You'll need basic armorer tools to remove and install the barrel itself, but no additional parts are required for a functional install.

Why does it include a different recoil spring?

Suppressors add back-pressure to the slide cycle. The included spring is engineered to manage that pressure and keep your pistol running reliably whether you're shooting suppressed or open.
