A suppressed 9mm shooting subsonic ammo is quiet...amazingly quiet.  Take that bulky hearing protection off of your ears and put it on your 9mm pistols, pistol caliber carbines (PCCs), and sub-guns instead!

But which 9mm suppressor should you choose?

Our Top 5 Best 9mm Silencers list is designed to help you compare features, functions, and more so you can make an informed choice.

1. Rugged Obsidian 9
2. Dead Air Wolfman
3. SilencerCo Omega 9K
4. YHM R9
5. Q Erector 9

1. Rugged Obsidian 9

The Rugged Obsidian 9 takes the top spot on our 9mm suppressor list because it’s truly great in just about every way.

With industry-leading sound suppression and minimal blowback thanks to its gas-sealed, non-slotted piston design, it sounds good and runs well on any 9mm pistol or carbine.

Earning a 4.9/5 star rating on over 200 customer reviews, the Obsidian 9 has stood out as a crowd favorite for years. "Quiet, elegant, cool. It’s a great suppressor. Backyard quiet with subs. Could not like it any more than I do." Said one verified purchaser. 

Thanks to its durable, keyed, gas-sealing baffles machined from 17-4 stainless steel, the Obsidian 9 is belt-fed rated on 9mm and can also handle some rifle calibers such as 300 BLK (subsonic), 9x39, and 350 Legend with relevant barrel length restrictions.

Being modular, you can quickly and easily transform the Rugged Obsidian 9 from a full length of 7.8 inches down to a very compact 4.85 inches. This allows the Obsidian 9 to transform between an ideal pistol suppressor to an ideal carbine suppressor, or to match your size and weight requirements with your intended use and preferences.

2. Dead Air Wolfman

The Dead Air Wolfman is a different kind of beast. This fully-welded, 17-4 stainless steel suppressor was designed for submachine gun use but is adaptable to many other applications as well. 

The Wolfman’s modular design allows the user to easily convert it from a full length of 7.5 inches down to a short length of 5.13 inches. Its mounting system is compatible with all of Dead Air’s P-Series of mounts, opening up many options from direct thread mounts in multiple thread pitches to KeyMo and Xeno QD systems, 3-Lug mounts, pistol boosters, and more.

The Wolfman has garnered over 150 reviews, customers exclaimed, "This can is absolutely versatile. Use it regularly on multiple platforms. And it operates perfectly." 

It’s larger in diameter than your typical pistol suppressor, but the Wolfman still runs and sounds great. You can even slap it on a 5.56 carbine, a 300 Blackout, or a 7.62x39 and run it like a standard rifle silencer. It’s full-auto-rated on 9mm, of course.

3. SilencerCo Omega 9K

The SilencerCo Omega 9K is a unique suppressor that carved out a fresh niche in the market when it was released. This compact, lightweight silencer is made of fully welded Cobalt 6 and 17-4 stainless steel, making it extremely tough and durable.

It’s rated not only for full-auto use on 9mm but also for use on both subsonic and supersonic 300 Blackout.

One customer told us, "The best 9mm can for size and money. Put this on my 9mm pcc but it is awesome to know I can toss it on a 300blk to shoot subsonic for a small package as well. Couldn't be more happy with the setup."

Compatible with SilencerCo Alpha series mounts, the Omega 9K ships with a 5/8x24 fixed mount (for 300 BLK firearms), a booster assembly minus the piston (pick up pistons separately in the thread pitches you require), and a 3-Lug tool should you grab a 3-Lug QD mount for use on MP5s and other submachine guns.

This is a great suppressor for taming your PCCs and 300BLK PDWs.

4. YHM R9

The YHM R9 is a lightweight, extremely compact 9mm suppressor that’s made from fully welded 17-4 stainless steel. Due to its tough construction, it’s rated for far more than 9mm, though!

The R9 is good to go on 300 Blackout, 223/5.56, 6.5 Grendel, 350 Legend, and even 308 Winchester on a 16-inch or longer barrel. Suppress nearly your whole collection with this one silencer.

Taking advantage of caliber ratings like that requires an adaptable mounting system, and sure enough, the YHM R9 is threaded at its base in the universal 1.375x24 HUB mount pattern. This opens up mounting options from dozens of manufacturers, including direct thread, QD systems, 3-Lug, pistol boosters, and more.

Obviously, this is a ton of utility from a 9mm suppressor, but even more surprising is the highly affordable price point. Furthermore, it sounds great on 9mm, 300 BLK, and other rifle calibers.

This is a great little suppressor at an awesome price.

5. Q Erector 9

The Q Erector 9, also known as the Q ERECT9R, is simultaneously the shortest, and longest 9mm pistol silencer on the market.

That’s because it’s fully modular. And we mean fully. Every single one of the Erector 9’s nine aluminum baffles can be removed, all the way down to running the front cap directly on top of the stainless steel blast baffle.

In its full configuration with all baffles in use, the ERECT9R is 8.7 inches long and weighs 8.1 ounces. Each baffle removed eliminates 0.34 ounces until you’re down to front-cap-on-blast-baffle, which weighs 5.0 ounces. “Hearing safe” on a 9mm pistol begins at around three baffles, and the full length is incredibly quiet. 

All of this modularity allows you to precisely tune the length and sound suppression desired for your specific firearm and use.

Even in its full length, because the majority of its weight is in the booster assembly, the Q Erector 9 feels extremely nimble and scarcely changes the balance of your pistol, while also being one of the quietest 9mm silencers on the market.

JK 105 CCX 9

JK Armament’s JK 105 CCX 9mm absolutely required an honorable mention here, as it has created a brand new category in the world of 9mm suppression.

This is the first 9mm silencer designed for concealed carry and self-defense use that employs a modern baffle design.

It’s fully modular like the Q ERECT9R, but thanks to its all-aluminum construction and insanely light 2.5-ounce weight in its full configuration, it runs reliably without the use of a booster at all! 

With a 1.05-inch diameter, the JK 105 CCX 9MM doesn’t even require suppressor sights. This is a unique silencer that’s so small and lightweight that you’ll hardly know it's there.

Our Top 5 Best 9mm Suppressors list covers the gamut of silencer styles available to suppress your 9mm pistols, carbines, sub guns, and much more. We hope this rundown helps you make an informed choice!
