SilencerCo Omega 9K

The SilencerCo Omega 9K is an ultra-compact 9mm suppressor designed specifically for pistol applications where minimal length is critical. At just 4.7 inches long and 7.1 ounces, the Omega 9K adds the least possible length to your host firearm while still providing meaningful sound reduction.

Built from 17-4 stainless steel with a welded monocore baffle stack, the Omega 9K delivers impressive durability in a small package. The suppressor is rated for full-auto fire and handles the increased back pressure of subcompact pistols without issue. The included piston and spring system allows for Nielsen device operation on tilting-barrel pistols.

As an NFA item, the Omega 9K requires ATF Form 4 approval (no transfer tax under OBBBA). The compact size makes it ideal for pistols where a longer suppressor would be impractical, though users should expect moderately higher sound levels compared to full-size 9mm cans. For shooters who prioritize compactness over maximum suppression, the Omega 9K delivers excellent balance.
