SilencerCo Omega 9K

SILENCERCO OMEGA 9K SUPPRESSOR - ULTRA-COMPACT 9MM SILENCER, FULL-AUTO RATED

The SilencerCo Omega 9K is an ultra-compact, full-auto rated suppressor for 9mm pistols, PCCs, and submachine guns, and it is also rated for subsonic and supersonic .300 BLK. Its tubeless construction combines Cobalt-6 and 17-4 stainless steel under a black Cerakote finish, keeping the 9K at just 4.54" long, 1.48" in diameter, and 7.3 oz. That small footprint keeps a pistol, PCC, or subgun short and maneuverable, which makes the Omega 9K a strong fit for home defense and tactical use as well as time at the range.

The Omega 9K uses SilencerCo's Alpha mounting system and ships with a 5/8x24 Alpha Direct Thread Mount for fixed-barrel hosts, plus the piston spring and retainer cap for handgun use. Handguns with unlocking barrels need a SilencerCo piston matched to the barrel threads, and the piston is sold separately. The Alpha ASR Mount pairs with SilencerCo ASR muzzle devices for quick attach and detach. For another quick-attach option on fixed barrels, the SilencerCo 3-Lug Mount works with a SilencerCo 3-lug muzzle device, while the Fixed Barrel Spacer takes the place of the piston spring when running a piston on a fixed-barrel firearm.

CAPITOL ARMORY'S OPINION

Compact 9mm suppressors used to take the edge off and not much more, since size came first and sound reduction came second. The Omega 9K changed that. At 4.54" long, it outperforms some full-size cans while keeping your host short and maneuverable. The 9K is right at home on PCCs and subguns, and it's our go-to compact PCC suppressor. Our staff runs it on MP5s almost exclusively, and most buyers put it on a CZ Scorpion, Sig MPX, or 9mm AR where overall length matters. On traditional pistols, there are quieter options out there, but anything quieter is about twice as long. If you love the size and want something even lighter, SilencerCo also makes the SilencerCo Spectre 9.

The .300 BLK 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, and not many 9mm suppressors can say that.
