Walther PPQ M1/M2 9mm Luger 4.6" Threaded Barrel with Protector - Matte Steel

The Walther PPQ M1/M2 9mm Luger 4.6" threaded barrel with protector is a direct replacement barrel built for shooters who want to run suppressors on their PPQ compact pistols or customize their platform. This matte steel barrel fits both M1 and M2 generation PPQ pistols chambered in 9mm, giving you a straightforward upgrade path without swapping the entire gun. The 4.6" length maintains the compact ergonomics of the PPQ while the 1/2" x 28 TPI threading is the standard pitch for most 9mm suppressor cans on the market.

Walther engineered this barrel with polygonal rifling, a design that optimizes bullet engagement and promotes better ballistic consistency compared to traditional lands-and-grooves. Whether you're building a dedicated suppressed carry pistol, setting up for indoor range work, or simply want the flexibility to add a can later, this barrel handles the job without surprises. The matte steel finish resists corrosion and won't snag light or draw attention—practical for working guns.

The kit ships complete: the barrel itself, a replacement spring to cycle the new barrel properly, and a thread protector so your muzzle threads stay clean and undamaged when you're not running a suppressor. Installation is straightforward for anyone familiar with basic pistol takedown. No gunsmithing required.
