Griffin Armament Suppressor Revolution 9 Mod 4 Blk

The Griffin Armament Revolution 9 Mod 4 is a modular 9mm pistol suppressor built for shooters who demand both versatility and reliability. This isn't a cookie-cutter can—Griffin engineered the Mod 4 generation from the ground up to solve real-world problems: baffle strikes, mounting security, and the maintenance headache that comes with carbon buildup. Whether you're running a compact carry gun or a full-size duty rig, this suppressor adapts to your setup without tools and keeps functioning smoothly even after thousands of rounds downrange.

The Mod 4 introduces Griffin's proprietary CARBON-GARD baffle technology, a feature that eliminates the frustration of carbon-locked baffles. High-temperature silicone o-rings seal the entire baffle stack, preventing lead and carbon fouling from accumulating between the tube and internal components. That means longer service intervals and easier—genuinely easier—maintenance when you do break it down. Disassembly is truly tool-less; you're not hunting for a wrench or screwdriver to reconfigure length or clean the core.

Security is paramount in a pistol suppressor, and Griffin addressed it head-on with the included EZ-LOK piston and booster assembly. The booster housing stays permanently fixed to the suppressor body, so tightening and loosening the can doesn't destabilize your mount. The O-ring-biased extension and front cap prevent unintended loosening during firing—a massive leap in reliability compared to legacy direct-thread designs. Pair the included piston with a Griffin EZ-LOK barrel adapter (purchased separately), and you've got a 15-fold improvement in mounting security. The suppressor ships full-auto rated and user serviceable, backed by a perpetual lifetime warranty.

Constructed from 17-4 H900 heat-treated stainless steel baffles and 7075-T6 aluminum for the tube and end cap, this is a suppressor engineered to last. Configure it short at 6.56 inches and 10.2 ounces for the most compact setup, or go full-size at 8.31 inches and 12.5 ounces for maximum sound reduction. Either way, you're running one of the few pistol suppressors that actually improves with use instead of becoming a maintenance nightmare.

Frequently Asked Questions

What mounting system does the Revolution 9 Mod 4 use?

The suppressor includes an EZ-LOK piston and booster assembly with a 3-Lug mount interface. To use the included piston, you'll need to purchase an EZ-LOK barrel adapter separately for your specific firearm. Alternative mounting options like Plan A mounts and legacy direct-thread pistons are available but sold separately.

Do I need tools to change the suppressor length?

No. The Mod 4 features tool-less reconfiguration, meaning you can switch between short (6.56") and full-size (8.31") configurations without any tools or adapters.

How often do I need to clean and maintain this suppressor?

The CARBON-GARD sealed baffle technology significantly extends maintenance intervals by preventing carbon and lead fouling from building up between the tube and baffle stack. Exact intervals depend on your usage, but the design is engineered to reduce the maintenance burden compared to traditional pistol suppressors. The suppressor is user serviceable and fully disassembles without tools.

Is the Revolution 9 Mod 4 rated for full-auto or burst fire?

Yes, the suppressor is full-auto rated, making it suitable for fully automatic and burst-fire firearms where legally permitted.
