SILENCERCO OMEGA 9K SUPPRESSOR - 9MM / 300 BLACKOUT PISTOL AND SUBGUN SILENCER

The SilencerCo Omega 9K delivers sound reduction that rivals suppressors twice its length in a package under 5 inches. At 4.56" long and 7.3 ounces, it adds minimal length and weight to PCCs, subguns, and pistols while still providing meaningful hearing protection. Fully welded tubeless construction from Cobalt-6 and 17-4 stainless steel handles full-auto fire and extended shooting sessions without a baffle stack to maintain or lose. The Omega 9K is rated for 9mm and 300 Blackout - both subsonic and supersonic - making it one of the few compact 9mm suppressors that can also run on a 300 BLK host without barrel length restrictions on supersonic loads.

The suppressor ships with a 5/8x24 Alpha direct thread mount. The Alpha mounting system is compatible with pistons for tilting-barrel handguns, 3-lug mounts for MP5-pattern hosts, and ASR mounts for quick-attach capability. 

CAPITOL ARMORY'S OPINION

Before the Omega 9K, compact 9mm suppressors were loud. They took the edge off but prioritized size over sound reduction. The Omega 9K changed that. At 4.56" long, it outperforms many full-size cans while keeping your host short and maneuverable.

Most buyers run this on a CZ Scorpion, Sig MPX, or 9mm AR where overall length matters. It works well on pistols too, though the direct thread setup adds some length compared to a dedicated pistol can with a booster. The Omega 9K shines on fixed-barrel hosts where you want to keep things compact without giving up suppression.

The 300 Blackout rating is a bonus. If you run a short 300 BLK pistol or SBR and want one can that moves between platforms, the Omega 9K handles both subsonic and supersonic loads. Not many 9mm-sized cans can say that.
