When you need to keep things quiet, be it for range etiquette or home defense needs, suppressors are a must-have.

Given that 9mm firearms are incredibly common these days, both as self-defense weapons and as EDC and tactical sidearms, let’s take an in-depth look at the best 9mm suppressors on the market and see which ones are suitable for 9mm use cases.

Best Overall:

First up is the SilencerCo Omega 45K – many people’s favorite and an incredibly versatile suppressor.

It’s definitely pricey, but overall well worth it thanks to its quality design features. For starters, the silencer uses a tubeless configuration that can deliver fantastic sound suppression without being too heavy or long.

It’s only 4.7 inches long and can reduce the sound of a 9mm shot from about 160 dB to 130 dB or so on average. It only weighs 8.8 pounds, so you’ll be able to use your favorite pistol without things feeling too off.

It uses corrosion-resistant cobalt-chromium alloy and stainless steel. Even better, you can use this 9mm suppressor with supersonic and subsonic ammunition – yes, that means you can combine the suppressor with other weapons as well. Thus, it’s a great long-term purchase for future use, not just for a single 9mm weapon.

It’s tough enough to work with submachine guns or rifles, and it’s easy to install over just a couple of seconds. There’s practically nothing to dislike about it aside from the fact that it doesn’t add a whole lot of accuracy since its short length limits how far it extends from the barrel.

In terms of flaws – it’s not a small cover, so it can add some unwanted bulk to the front of your firearm. It’s also built for a maximum dimension of 1.5″ so it won’t fit over some of the more popular cans, such as a SilencerCo Omega.

That said, when it comes to durability, stability, and effective heat reduction, the Magpul is at the front of the class.

Pros

  • Very easy to install and remove
  • Short and lightweight
  • Super durable
  • Can be used for multiple weapons

Cons

  • Not a big accuracy booster
  • Not as much recoil reduction as other options

Budget Option:

Here’s a compact and slightly less expensive 9mm suppressor. The Advanced Armament Illusion is a good choice for budget-minded shooters who still want something that can deliver great suppression for typical 9mm pistols.

It’s a versatile model, using a patented “special performance system” that can ensure excellent operation with a broad spectrum of different pistol models and types.

You’ll be able to quickly and easily adjust how the suppressor rotates on to your pistol, and you can also rotate the silencer to better suit your sight picture depending on how high the weapon’s sights sit on your gun. This ensures that you won’t have to work with an obstructed sight under any circumstances.

The suppressor comes with a cone baffle stack that can easily be removed for maintenance without needing tons of tools. The baffle helps your ammunition move out smoothly, improving accuracy for every shot.

The overall suppressor is made with stainless steel and has a nitride finish that ensures long-term durability and corrosion resistance. It is a little long for some smaller pistols, so be sure that it’ll fit with your firearm before finalizing a purchase.

Pros

  • Can easily be rotated for a good sight picture
  • Comes with a cone baffle to improve accuracy
  • Baffle can easily be removed for maintenance
  • Made with great materials and nitride finish

Cons

  • Can be a bit long for some pistols

Best Recoil Reduction:

This suppressor is designed for 9mm Luger pistols, and it’s made with a titanium tube that guarantees excellent durability without adding a ton of weight to your pistol. It also comes with stainless steel baffles for added performance.

The attaching end of the suppressor uses a barrel spacer set up that links it securely to your weapon. Screwing in the suppressor only takes a couple of seconds, as does uninstalling the suppressor if you want to replace it with a different barrel attachment. This special setup process also means that it works well with any tilting barrel pistols – a special booster comes with the purchase.

Very little barrel movement with the SDR9 in place.

We also like that the suppressor can work to reduce the recoil you feel by a slight but noticeable amount. Again, this isn’t as powerful as something like a dedicated muzzle brake, but it’s a nice bonus.  All in all, it’s a suppressor that works with a wide variety of pistols and that does a great job of suppressing noise while only weighing 12.6 ounces.

The downside is that you’ll have to clean and calibrate this suppressor relatively frequently. But compared to all the benefits, that’s not much of a flaw.

Pros

  • Excellent titanium body
  • Very easy to attach to a wide variety of guns
  • Works with tilted barrel pistols
  • Reduces recoil noticeably

Cons

  • Needs lots of maintenance and calibration

Full Auto Option:

Sometimes you want a 9mm suppressor for a fully automatic weapon instead of a traditional, semi-auto application.

That’s what the Dead Air Wolf is all about. It was built for short barreled submachine guns of all kinds. It’s design offers a more modular suppressor that features a full-length orientation for longer weapons and a compact configuration for smaller pistols and handguns.

Regardless, it’s a durable piece of equipment that’s easy to clean and can withstand tons of fully automatic fire without decreasing in performance. It weighs either 7.5 or 14.7 ounces depending on its configuration; either way, that’s fairly lightweight for most folks. The compact orientation is also only 4.1 inches long.

It’s ultimately tough enough to be used with 300 blackout rounds. Just keep in mind that the barrel is a bit thick – even if it doesn’t weigh a whole lot, this might throw your balance off a bit. But it does ensure that the suppressor works wonders when it comes to reducing noise output.

Pros

  • Can be used from pistols or submachine guns
  • Both configurations are lightweight
  • Very durable
  • Works with 300 blackout rounds

Cons

  • Might affect the balance of your weapon
  • May require suppressor-height sights on pistols due to the diameter

Most Innovative:

Alright, so this isn’t a dedicated suppressor by itself. Instead, it’s a 9mm pistol with “integral suppression”, meaning that its shots are always suppressed since the suppressor module is essentially built into the handgun’s frame. Still, we think it’s a great choice if you want premium performance and are willing to put down some extra money to acquire it.

It’s a semiautomatic pistol that is shorter than practically any other traditional 9mm handgun with an additional suppressor attached. It fires 147 gr, 9mm pistols at sounds of about 139 dB – talk about suppressing power!

It also uses Glock magazines, so you can combine the pistol with a variety of excellent accessories.

It’s a phenomenal pistol with barely any recoil and an ergonomic handle. Subsonic and supersonic ammo both work with this pistol and its integrated suppressor. You can also use a modular control to extend the barrel a little bit for added accuracy, though this does increase the sound of the weapon.

Pros

  • Suppressor is built into the handgun
  • Very little recoil
  • Excellent noise reduction
  • Comfortable grip
  • Easy to accessorize

Cons

  • Very expensive

What to Look for in a Quality 9mm Suppressor

Various Suppressors
Lots of 9mm suppressors

The different factors that distinguish 9mm suppressors from one another can impact how well they suit your firearm and its intended use. Let’s break them down one by one.

1. Material

What kind of material? Metal, duh.

Obviously, the material construction of a 9mm suppressor matters a lot. Practically all of them will be made of some type of steel, usually stainless, titanium, or something similar.

You can also find many suppressors bolstered by durable polymers that can either reinforce the steel for added stability, increase noise reduction, or minimize heat transfer even further.

Hardier and lighter materials are almost always better – but they tend to increase costs. The lighter the suppressor, the less it affects your weapon’s balance, and the more accurate you will be with it attached.

2. Recoil Reduction

Some of the best suppressors can also help balance the recoil of your weapon. Keep in mind that this is a side effect, not the focus of the suppressor.

You shouldn’t expect it a suppressor to reduce your recoil in the same way that a muzzle brake often can. Still, suppressors that can add a little bit of extra stability to your weapon are always great choices.

3. Compatibility

Ensure that a given 9mm suppressor fits with your weapon and is rated for the shooting you do.

Some suppressors are only designed to be used with certain 9mm pistols, while others are suitable for compact and full-size handguns or even full-auto firing.

Still, more suppressors can work with longer rifles chambered for 9mm ammunition, like certain AR-15 builds cobbled together by hobbyists.

4. QD or Direct Thread

Direct Thread

Certain suppressors are really easy to screw onto the end of your gun via direct threading — such as a rifle in 5.56 NATO caliber threaded for 1/2-28. A suppressor threaded in 1/2-28 simply screws onto the end of the barrel or flash hider. It’s the cheapest option, requiring nothing other than the barrel and suppressor, which means it’s also the lightest and least expensive route to quieting down your rifle (or multiple common-caliber rifles). Direct threaded suppressors can back off over time, so you’ll need to make sure it’s tightened to spec before shooting or risk it backing off to the point of causing a (rather expensive) failure.

Quick Disconnect

Quick Disconnect (QD) will often require a dedicated adaptor but it makes attaching and disconnecting a suppressor incredibly easy.  They’re also convenient – in that you can mount an adapter to a muzzle device on multiple rifles and swap your suppressor all day long. 

QD options tend to be more expensive, as you’ll need an adapter for every gun you run, plus they add weight.   

5. Weight

Lastly, be sure to keep the weight of a suppressor in mind before purchasing. Again, lighter suppressors are almost always better since they don’t throw off your aim with your weapon when attached to the barrel. Heavier suppressors might be tougher but can make a firearm more difficult to use accurately.

See what happens when you overdo it?

Conclusion

At the end of the day, all of these 9mm suppressors are great choices. The Silencerco Omega Silencer is a good all-around choice for most users thanks to its asking price and excellent design choices.

But we feel any of these will work well for lowering the noise output of even the loudest 9mm pistols or submachine guns and help you complete your hunt or tactical operation successfully. Good hunting!
