Why This Beats the Competition
Having tested suppressors from our Spring TX CNC floor to the 100-yard range we walk to, the Omega 9K delivers where it counts:
- Stellite baffles withstand full-auto fire better than 17-4 steel
- 1.375″x24 threads work with most booster assemblies
- Shorter than comparable models without sacrificing decibel reduction
- Silencerco’s reputation for customer service matters when you’re 200 days into ATF paperwork
Key Features
- Full-auto rated for sustained fire
- Direct thread and ASR compatible
- Stellite baffle construction
- User-serviceable design
- Tested on subguns down to 4″ barrels

Who This Is For
Buy it if:
- You run a 9mm PCC hard enough to need full-auto rating
- You prioritize compact size for HD setups
- You want a suppressor that’ll last through multiple Form 4 transfers
Skip it if:
- You only shoot .45 ACP (check our .45 suppressors instead)
- You need maximum sound reduction (consider longer models)
- You’re budget shopping (we carry affordable options too)

Where can I buy the Omega 9K online?
