Description
Primary Weapons Systems built its name on piston-driven ARs, and the BDE line of suppressors carries that same engineering-first mindset. The BDE 9mm centers on a baffle core printed from aerospace-grade 6AL-4V titanium, a process that produces internal geometry you simply can't cut on a lathe, all while coming in lighter and stronger than traditionally machined titanium. At roughly half a pound and 1.45 inches in diameter, it hangs off the end of a pistol without turning your handgun into a boat anchor, and it's rated for 9mm hosts plus subsonic .300 Blackout if you want to stretch its legs on a bolt gun or braced pistol.
Modular Baffles Make the BDE 9 Two Cans in One
The removable aluminum baffles are where this can earns its keep. Run the full stack when you want every last decibel knocked down, or pull sections off for a shorter, handier package that still takes the bark off a 9mm. PWS taper-threaded the baffle connections specifically to fight carbon lock, so the sections come apart for cleaning even after a lot of dirty pistol ammo, and they won't walk loose under fire either. Symmetrical internal baffle notches help keep your point of impact consistent, and the textured exterior cuts down on heat mirage when things get warm.
Mounting the PWS BDE 9mm to Your Host
The rear of the can uses the industry-standard 1.125×28 TPI thread pattern, which means it plays nice with the huge ecosystem of pistons, fixed mounts, and boosters already on the market. Grab a piston that matches your barrel's threads and you're in business on just about any threaded 9mm pistol, or set it up fixed-mount for a PCC or subgun.
Finish That Shrugs Off Range Days
A PVD coating over the titanium paired with Type 2 anodizing on the aluminum sections gives the BDE a tough, easy-to-clean black finish inside and out. It's a smart, lightweight, adaptable 9mm can from a company that sweats the details, and it holds its own against silencers costing quite a bit more.

Frequently Asked Questions
Do I need a separate piston to run the PWS BDE 9 on my pistol?
Yes, the BDE 9 uses the widely adopted 1.125×28 TPI thread pattern at the rear, so it accepts most industry-standard pistons and mounts. Pick up a piston that matches your barrel threading, typically 1/2×28 for most 9mm pistols, and you're set. That same pattern also opens the door to fixed mounts for PCCs and other non-tilting-barrel hosts.
Can the BDE 9mm handle .300 Blackout?
It's rated for subsonic .300 Blackout in addition to 9mm, which makes it a handy crossover can. Keep it to subsonic loads on the Blackout side and it will serve double duty between your pistol and a suppressed .300 BLK setup.
How does the modular design on the BDE 9 work?
The suppressor ships with removable aluminum baffles that let you change the overall length and sound reduction level. Run it full length for the quietest performance or shorten it up when a compact package matters more. The baffle sections use taper threading, which keeps them from carbon locking together or loosening during fire.
Is 3D printed titanium as durable as machined titanium?
PWS prints the core from Grade 5 6AL-4V titanium using additive manufacturing, and the result is lighter and stronger than traditionally machined titanium. Printing also allows internal baffle geometry that conventional machining can't reproduce, which benefits both sound performance and accuracy.
