5 Best 9mm & .45 ACP Suppressors

Looking for a silent pew? You’ve come to the right place.

The wide world of the NFA encompasses the most fun guns and accessories.

If you are willing to brave forms, fingerprints, $200 bucks, and a wait time best described as horrid – then you can access some of the coolest toys around!

The NFA is a giant paperwork and tax mess that makes freedom tough to enjoy…so you want to make sure you’re spending that money and time on a tool that is truly quality.

Suppressing the good ole 9mm AND .45 ACP is easy and there’s plenty of options out there.

By the end you’ll know the best suppressor for your handgun, PCC, or sub-gun.

Should You Go Multi-Cal?

The NFA (National Firearms Act) is annoying and encompasses a $200 tax stamp (which thankfully hasn’t changed since it started).

Plus it takes many months to actually process.

If you were thinking of a dedicated 9mm suppressor…you might want to rethink again.

You don’t want to hinder your future suppressing options because you only have a 9mm right now. With a multi-caliber suppressor you’ll be good to go from tiny rimfire all the way up to .45 ACP.

And some will even handle .300 BLK subsonic rounds.

And if you’re thinking of applying for the NFA without a gun trust…don’t. Definitely go with one. We use Capitol Armory’s $79 option that’s super easy and done from the comfort of your own couch.

Hearing Safe

Before we dive into some awesome silencers, let’s take a moment to talk “hearing safe.”

The National Institute for Occupational Safety and Health’s threshold for hearing safe is 140-decibels. Meaning, anything higher than that will damage your hearing.

An unsuppressed .22 LR measures about 145-decibels while a “normal gunshot” (we’re going to guess your average 9mm, .45 ACP, etc.) comes in around 165 to 170 decibels.

Suppressor Noise Thermometer

On the other hand, most average caliber suppressors cap out around the 130 to 140 decibels…scrapping below that hearing safe threshold. Though, .22 LR suppressors significantly reduce the volume to 115-decibels.

Why am I telling you all this?

Because a silencer doesn’t mean you shouldn’t also wear hearing pro. It just means that you might not need the heavy-duty pair you usually tote to the range.

We’re also including manufacturer specs for dBs. The real world numbers will vary on your gun and ammo…but it gives you a good idea of what is truly “hearing safe.”

Silencer Central’s Banish 45 might be the perfect solution if you have a couple handguns that need suppression and you don’t have loads of cash to pay for multiple tax stamps and silencers.

2. Rugged Obsidian 45

Want a super durable steel that can take anything a handgun can throw at it? Check out the Rugged Obsidian 45.

You can unscrew the top cap to make it shorter. Plus…even in the short mode it still sounds pretty good.

And since pistols are dirtier…it’s a good perk that you can take it apart to clean.

It also takes SilencerCo Alpha mounts so it’s super modular.

There’s also caliber specific endcaps but we have found negligible effects of having the correct one if you’re sizing down.

Manufacturer Specs (Rugged Obsidian 45):

  • Decibel Rating: 129.3dB for .45 in full config; 123.7dB for 9mm in full config
  • Rating: belt-fed pistol up to .45 ACP; rifle calibers up to .300 BLK, .350 Legend, & .450 Bushmaster

3. CGS Mod-9

The CGS Mod-9 has an initial steel booster and one steel baffle…with the rest aluminum.

You won’t be going full-auto for long periods of time but it will take anything a regular handgun can do. We recommend pausing a little after the equivalent of 60 rounds for it to cool down.

However, that steel in the back gives it a great balance on most handguns. And the little extra weight in the back helps mitigate the more pronounced *cachunks* (first round pop) of shooting with suppressors.

Another cool thing? It’s good for rimfire rounds and also breaks down for easy cleaning.

Manufacturer Specs CGS Mod-9):

  • Rating: rimfire to .300 BLK Subsonic
  • Weight: 10 oz
  • Diameter: 1.37″
  • Length: 7.7″

4. SilencerCo Osprey 45

No pistol suppressor list is complete without the SilencerCo Osprey series.

Today we have the Osprey 45 with its iconic rectangular shape which keeps it under the front sights…negating the need for suppressor height irons or switching to red dots.

It is a sealed can but it will likely outlast your guns. But because you can’t crack it open to clean it…don’t shoot rimfire through it since they are so dirty.

For it’s size it’s also very quiet.

5. Dead Air Ghost 45M

We love the Dead Air Ghost 45M for its modularity.

Of course it can reduce it’s length and open up for cleaning.

But its last few baffle stacks are aluminum to reduce front weight. All the more abused parts are in the beginning so you’re still GTG for full-auto usage.

Plus there’s 3-lug adapters for your favorite MP5 clone.

Keeping it Quiet

Suppressors are just fun. I fired my first suppressed pistol at SHOT many years ago and was hooked. I loved how the gun felt, how comfortable and quiet it was, and just how effective they are.

It’ll never be as quiet as movies make silencers out to be, but the reduction in noise, flash, and concussion makes shooting way more comfortable. The added reduced recoil and muzzle rise is also a nice touch.

    There are quite a few grammatical, spelling errors, and then some ‘wtf was that supposed to say?’, moments as well in this article. Is there an editor (they’d have to be a really shitty editor if there is) or are you looking for one?
    Because I enjoy reading (or trying to...) your articles and would love to help you present a much more clear, concise, comprehendible, and therefore more helpful product as well as presenting your organization and yourself as a much more professional and trustworthy source to your readers, colleagues, and critics.

      Thanks for the feedback! We're working on updating older articles as we speak to bring them up to speed on current PPT standards. So, just hold tight. Thanks!

    Is there a single recommended can that would work well with 9mm glock, sig MPX, and ar 15-22?

    January 23, 2021 6:49 pm
    • Eric

      Pretty much any 9mm can that you can take apart to clean will be fine on a .22. If it has a modular mount, you can use a booster for 9mm pistols and rim fire, and a fixed mount on rim fire or 9mm PCC

    What do you think of the XCaliber SeaFire Diamond 45ACP from The Silencer Store? Am looking for quality suppressor that won't break the bank. I am planning to add a 1/2X28 piston to it so I can also use it on my 9mm Springfield XDM with raised sights for home defense. What say you?

    The CGS Kraken (called the mod 9 now) is one of the best 9mm fullsize handgun cans and it might be the quietest too.

    It should be noted that Dead Air only makes limited runs of the Wolf since they replaced it with the Wolfman which is very similar to the Omega 9K in size but has the benefit of the extra removable baffles.
