Handgun Gear: Best 9mm Suppressor Choices


The top 9mm suppressor options to put a lid on your nine.

What are the best 9mm suppressors:

The most shot centerfire cartridge in the United States, the 9mm is as pervasive as the air we breathe. Chances are you have one in your collection, even if you’re lukewarm on the caliber. Admit it.

Its prominence is no mystery. The caliber is easy to shoot well, is a capable self-defense option, and is perhaps only eclipsed by the .22LR in economy of ammunition. It is also something else – eminently suppressible. The right can and your pistol – or pistol caliber carbine for that matter – is as stealthy as it gets in the centerfire world. That raises the question, however, what is the right 9mm suppressor?

No easy answer there, like choosing a gun it matters what’s right to you. There are a few facets you’ll definitely want to consider when shopping for an accessory that’s potentially as expensive as your pistol. Among these are:

  • Size: Do you require something short and dexterous for shooting on the move or will a full-sized unit fit the bill.
  • Weight: Will it throw the balance of your gun out of whack?
  • Sound Suppression: How much do you need to achieve your goals?
  • Flexibility: Is the suppressor dedicated to one caliber or will it sever multiple guns?
  • Cost: How much can you afford, given you have a tax bill on top of costs?

As usual, you’ll have to assess your own situation and what suppressor ticks off the right boxes. In the meantime, we’ll give you a taste of some of the best choices out there today. On top of their games, these five 9mm suppressor options fill about every conceivable niche and will certainly keep a lid on your nine.

Gemtech GM-9


Generally a large investment, the GM-9 is priced to actually leave money left over for ammo – subsonic or otherwise. And you’re not compromising. Into the game early, Gemtech knows suppressors and how to get the most out of their tested designs. Furthermore, the company touts the GM line as its most advanced, even at its more affordable end.

Not strictly a 9mm suppressor, it has some flexibility as it is also rated for subsonic 300 Blackout ammunition. Certainly, if you shoot these calibers the GM-9 is a dynamite deal few others in its class match. Not that everything on the can is a bed of roses. It’s long, particularly for a pistol suppressor – 7.8 inches with mount. Livable as a shooting range option, more than that – particularly situations where you require dexterity – it could prove burdensome. The bright side, the suppressor more than makes up for its length with its weight, which is about as much as a whisper – 6 ounces.

Where the rubber meets the road – sound suppression – the GM-9 has a lot of bang for the buck. With an average 30dB of noise reduction, the suppressor performs with the big boys, but costs considerably less.

The other value to the GM-9, durability and ease of maintenance. A black Cerakote finished aluminum tube, the suppressor is up to the test of general use. And cleaning, the monocore baffle makes it a second thought. It easily separates from the tube and takes any worry about getting baffles out of order of the equation.

Sound Reduction: 30dB
Diameter: 1.25″
Length: 7.8″
Weight In Units: 6oz

CMMG DefCan 9

Not everyone shoots 9mm from pistols. In turn, not every 9mm suppressor need be designed for handguns. A fact plain as day to AR specialists CMMG. Jumping into the noise reduction game this past year, the company tailored the pistol-caliber members of its DefCan line for sub-guns and AR pistols, rifles and carbines.

Unmistakably, the DefCan 9 looks the part. While extremely slender (1.38 inches), it is long – long as they come on this list at least. At 10.25 inches, even if it could fit your pistol, you wouldn’t want it there anyway. On a long-gun, SBR or AR-pistol, it’s a completely different story. That extra length to dissipate gases does a number on a gun’s report, cutting it 32dB on average.

For its size, the DefCan 9 should prove a second though mounted, given its featherweight. The suppressor adds a scant 10 ounces to a firearm, which is akin to adding many lighting options to the fore of a rail. Aluminum construction keeps the unit light, as well as imparting it with some desirable thermal properties, dissipating heat in a flash.

In its guts, the DefCan 9 uses a stack of seven M-style baffles, each of which has a squared port on the aperture. The design point further improves noise reduction, directing gas particles laterally inside the tube. The suppressor is completely sealed, in turn, not user accessible. However, it requires no routine cleaning.

DefCan 9 Specs
Caliber: 9mm
Sound Reduction: 32dB
Length: 10.25″
Diameter: 1 3/8″
Weight: 10oz
Finish: Hard Coat Anodized
Attachment: Bi-Lock Flash Hider with Included Peel Washer, Threaded 1/2-28

SilencerCo Omega K 9

It’s difficult to make a suppressor list without a SilencerCo Omega K rearing its head. That goes for the ubiquitous 9mm. Residing on the tonier end of the market, the Omega 9K is hardly money wasted. It’s light, compact and does what it was designed to do – keep a lid on your noisy guns.

Among the smallest 9mm suppressors on this list, the tubeless Omega K adds a negligible 4.7 inches to the overall length of your gun. Yes, you’ll still know it’s there, but if you happen to compete or engage in any shooting activity that requires agility the suppressor won’t hang you up. Furthermore, at 7.2 ounces, the can won’t knock your pistol out of balance as greatly as heavier options.

Made from stainless steel and stellite (a cobalt-chromium alloy), the Omega K is wang-leather tough. The abrasion-resistant and extremely hard alloy is renowned for its wear resistance, standing up to long shooting sessions as well as the most rugged external punishment.

As to the suppressor’s performance where it counts – noise reduction – it’s a bit below par compared to longer options. SilencerCo pegs the average report of a 9mm outfitted with an Omega at 131.5dB, around 28.5dB of noise reduction. Not top of the charts, not a slouch either – especially for its size. If you need a push over the edge to spend the money, it can digest sub and supersonic 300 Blackout rounds as well.

Omega K 9 Specs
Caliber: 9MM AND .300 BLK
Muzzle Average: 9MM: 131.5 DB , .300 BLK SUB: 133.7 DB, .300 BLK SUPER: 138.4 DB

    • Advanced Armament Illusion 9

      Dancing to its own beat, the AAC Illusion 9 is perhaps the most unique 9mm suppressor choice out on this list. Yet, it works… exceedingly well.

      A big check in the plus column, the 9mm specialist works with the sights already on your pistol. ACC achieved this through embracing what is known as an “eccentric” suppressor design. In particular, this means more of the can’s volume is below the bore, instead of equally distributed. This makes the Illusion a mount-and-shoot affair, no need to upgrade to high-rise sights to get on target.

      Reed slender, the Illusion doesn’t appear to have the space required to muffle a pellet gun, let alone a 9mm. It makes up for this with length and plenty of it. The suppressor measures 7.88 inches, enough to make it a bit unwieldy on the most compact pistols. Baffle geometry also plays its part in noise reduction, pushing gas particles to the larger part of the expansion chamber and letting it do its job.

      To that end, it performs splendidly. AAC lists a full 33dB of noise suppression from the Illusion and on the range that is absolutely believable. It brings a nine’s report to mouse-fart level. Even lower from there if you shoot it wet.

      The Illusion is an investment, but if you’re truly looking to dampen your pistol you’ll get your money’s worth.

      Illusion 9 Specs
      Caliber: 9mm
      Weight: 10.4 oz
      Length: 7.88”

      Griffin Armament Revolution 9

      Adaptable to your requirements, the Revolution 9 is akin to two cans in one package. Modular in design, the 9mm suppressor has two configurations – full length and what Griffin Armament’s call its “K” version. The latter arrangement shaves 3-inches off the Rev 9, making for a more adroit unit, ideal for a nightstand gun or the like.

      You guessed it, you run small, you run louder. Never fear, you’ve got plenty of sound suppression to work with in the Rev 9. Booster housing on and all eight baffles in, the 7.6-inch suppressor shaves an impressive 34dB off a 9mm’s report. In the smaller “K” configuration, three baffles removed, it still provides a respectable 32dB of noise suppression.

      Griffin Armament designed the Rev 9 as more than a range toy, stoutly constructed with stainless steel baffles and a hard-coat anodized aluminum tube. This, as you might expect, make the suppressor a bit weightier – 11.2 ounces at full length. However, if you can stand a little more noise the “K” configuration drops the Rev 9 to 9.7 ounces.

      Overall, it’s a clever and flexible concept that should cover all your bases, whatever they might be.

      Revolution 9 Specs
      Diameter: 1.375”
