Updated 75/28/20

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.

Arguably, the cut-down size would work on a pistol, except along with diameter the Wolf is fairly hefty at 14 and 7 ounces in its two configurations. However, if you mainly run sub or carbines, this will work for your sidearm in a pinch.

CGS Mod 9

Doesn’t matter if you’re talking handguns or precision optics, striking a balance is always a challenge. Suppressors are no different, though CGS goes a long way to finding middle ground with its MOD 9. Lightweight, yet durable and an excellent noise-reduction profile, the 9mm suppressor walks the line on all the desirable attributes shooters search for in a can.

Yeah, the MOD-9 is a full-sized can, measuring in at 7.7 inches in length, with a 1.37-inch tube diameter. If you aren’t kicking in doors for a living that should prove more than manageable, especially for the payoff. CGS has cooked up a quiet suppressor—mouse-sneeze quiet. Of course, this varies depending on ammo and barrel length, but expect most 9mms with a 4-inch-plus fire tube to generate between 113 and 120 dB with a MOD-9 mounted. Aluminum is the main ingredient of the build, including the suppressors 6 baffle stack and tube. This keeps it a light 10 ounces. On a last note, the piston assembly is impressive, with 12-point rotational adjustment to dial in for impact shift.

Standby 9mm Suppressor Options

Rugged Suppressors Obsidian 45

9mm Suppressor Rugged-Suppressors-Obsidian

Technically, the Rugged Suppressors Obsidian 45 is much more than a 9mm suppressor. Rated for .45 ACP, the extremely robust device handles some real heavyweights, including .450 Bushmaster, .45-70 Government and .458 SOCOM—with the appropriate barrel length. Quite a spread, to say the least, making the Obsidian an ideal choice if you not only want to hush up your ‘Nine’, but a load of rifles and carbines.

The versatility doesn’t stop with caliber compatibility. Modular, you can tailor the Obsidian to your firearm and application with an 8.7-inch full configuration and 6.7-inch K configuration. This gives you ideal lengths for use on your rifle or pistol. Either way, the suppressor is full-auto rated for all pistol calibers, as well as .300 Blackout and does a number on your gun’s report. At full length, it knocks a 9mm pistol’s report down to 123.7dB run dry. The unit features a non-slotted piston design, cutting down on gas blowback from handguns, and is constructed of a durable aircraft-grade aluminum tube and stainless steel baffles. This is a true jack-of-all-trades.

Dead Air Odessa-9

9mm suppressor odessa

Sound suppression, for obvious reasons, is what headlines suppressor innovation. But what about the little things that make a can more functional and practical to a greater swath of shooters? Dead Air homed in on these and, it’s safe to say, knocked it out of the park with the Odessa-9.

Among the most notable aspects is the 1.1-inch tube.
On the surface, the slim design might not sound like much, until you consider it is fully compatible with nearly every pistol’s stock sights. Moreover, the 9mm suppressor adapts to any application you put in front of it, given its modular design. You can run the Odessa with all 11 baffles if noise suppression is at a premium or with just one if you need to take the edge off your gun’s report. And it will do its job when run short, with four baffles putting subsonic ammunition at or near safe hearing levels. Full length, the 10-ounce suppressor reduces subsonic 9mm ammo to around 122dB. There’s little argument, the Odessa-9 makes going suppressed a whole lot easier.

SilencerCo Osprey

9mm Suppressor osprey

SilencerCo’s uniquely shaped Osprey isn’t a spring chicken by any stretch of the imagination. But that doesn’t make the 9mm suppressor any less effective at doing its job. It’s among the best at cutting down noise, as well as offering one of the best possible shooting experiences.

The eccentric suppressor (meaning the bore doesn’t run down its center axis) offers a load of advantages over its cylindrical counterparts. First and foremost, it provides more internal volume for gases to expand, thus offer more noise-reduction capabilities. A 9mm’s noise is reduced to 127dB, which is dynamite. Furthermore, it’s off-center design helps it stay out of your sight picture, in turn you get to keep your stock sights. Yet, the device is extremely lightweight, compose aluminum tube and baffles, and stainless steel blast baffle. Top noise reduction capabilities, user-friendly and lightweight—what’s not to like?

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.

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.

Caliber: 9mm
Weight: 10 ounces
Length: 10.25 inches
Diameter: 1.375 inches

Average Decibles: 128db (estimated)
MSRP: $700

SilencerCo Omega 9K

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 9K Specs

Caliber: 9MM AND .300 BLK
Weight: 7.2 ounces
Length: 4.7 inches
Diameter: 1.48 inches
Materials: Stellite Tube, Stainless Steel Baffles

    • 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.

      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.
