The New BANISH 9 Suppressor and Why You’re Going To Want One
June 2, 2025Posted by derrek.sigler
Have you heard the news? BANISH Suppressors has an all-new pistol silencer out – the BANISH 9. As you may have guessed from the name, the new silencer is designed for the 9mm cartridge and as you also likely have surmised being from BANISH, it is pretty advanced. The new can works with 9mm pistols, rifles, and PCCs, as well as other popular cartridges like .380 ACP, .300 BLK, 350 Legend, and more.
“We designed the BANISH 9 with the goal of maximum sound suppression across a variety of firearm platforms, and while we focused on 9mm, we wanted to accommodate a range of popular chambering,” said Lukas VanLaecken, BANISH Suppressors Director of Engineering. “Not only is it one of the quietest 9mm suppressors on the market, it's also lightweight and versatile, and utilizes BANISH's Micro Booster™, a proprietary Nielsen device assembly, along with additional direct thread options for pistol caliber carbines.”

With the addition of the new BANISH 9 silencer, BANISH now has three distinct options in the pistol suppressor market. You may wonder which is the best suppressor for your handgun needs. If you're like me, you want all three. But how do these three offerings stack up against each other? Each has specific capabilities that make it special. Let's review.
BANISH 9: The latest full-size silencer for maximum 9mm suppression
The BANISH 9 is the latest model and boasts some amazing technology that you should consider. According to internal testing at BANISH, they claim it is one of the quietest 9mm suppressors on the market. With a 34 dB reduction in sound output, that says a lot. You can learn more about how suppressors control sound output here.
The BANISH 9 is made from Titanium with an anodized aluminum outer tube and end cap. It uses 14 baffles and as you would expect from BANISH, it is completely user serviceable.
One of the biggest advancements the BANISH 9 makes is the new BANISH Micro Booster™ We all know that some pistols require a Neilsen Device to operate with a suppressor. This is due to the pistol using the energy of the blast to cycle the next round. A suppressor can absorb too much of that energy, and with the added weight of the can on the barrel, the pistol won’t cycle. A Neilsen Device adds a spring-loaded piston to the end to help the pistol cycle. The BANISH Micro Booster handles this in the most compact design on the market, adding very little weight and length to your firearm. BANISH is the first company to do this and now they have created a new category of products for the competition to try to emulate.
It is becoming more common to see pistol suppressors on the range and everywhere else. The 9mm is known as a finicky round to suppress, however, due to the lower power of the round. That and some pistols just are known for not cycling well with a suppressor. Yes, I’m still looking at you Glock. That’s not a dig a Glock or any other pistol manufacturer though. I like Glocks. I also like Sigs, too. You just need a threaded barrel for them. (And I have it on good authority that you’ll soon have a place to get threaded barrels, too.) The engineers at BANISH say the BANISH 9 works well with every pistol out there. I’m trying to personally test that theory out and will report it here as soon as I can make it happen. Stay tuned.
You want a BANISH 9 because it is the quietest full-size 9mm suppressor available. That and it works on every pistol and PCC. This is a case where silence speaks volumes and the BANISH 9 has a lot to say.
If you haven’t heard yet, the BANISH 9K made a big impact within the firearms world when it was released. It is a fully-titanium suppressor that is made using additive manufacturing processes that are very similar to 3D printing, but a bit more complex. Basically, a laser forms granulized titanium into the can. Because of this, the suppressor is extremely light and compact, a fact that makes it work on many pistols without the need for a Neilsen device. It only weighs 2.7 ounces!
The BANISH 9K is offered with 1/2x28 standard or 13.5x1LH metric direct thread options, so you can fit it to your Sig and some older HK models. A few folks have reported that it doesn’t work with their pistol without a Neilsen device (aka a piston). These are mostly some Glock models and usually with certain ammo – usually light practice ammo that doesn’t pack much punch. It makes the BANISH 9K too much weight on the barrel to cycle. It’s an easy fix and again, it is only select pistol brands – and you know who you are.
Why do you want one?
That’s easy, it is just too cool to not want one. The biggest differences between the BANISH 9 (B9) and the BANISH 9K are pretty easy to spot. The 9K is printed versus the B9 that is made in the traditional way. The B9 is quieter and user serviceable, plus it comes with the Micro Booster (you can opt out of the Micro Booster™ if you want). The 9K is smaller, lighter, and simpler.
Let me make things easier for you – You really want both. I know I do. In fact, I ordered both. And yes, if you read my earlier story on the 9K, you know I wanted a Springfield Echelon to mount it to. Well, I got one, but I’m going to mount the B9 to it. For the 9K, I also bought a Springfield Armory Hellcat Pro. Why did I buy both pistols, you wonder? Because I was left unsupervised in the gun shop and I’m financially irresponsible. No, that’s just a joke. Besides, if my wife reads this – They were on sale, I swear! And come on, this is America and I can buy both! In fact, I may go buy some more. Freedom is a great thing.
The BANISH 45 was the lone pistol suppressor in the lineup for some time until the 9K came out. Being rated for a .45 ACP, it can handle any pistol caliber from there down, including rimfire and some rifle cartridges, too. BANISH designed it to be universal, where you just swap pistons to change calibers and firearms. It’s modular, too, so you can adapt it to what type of shooting you are doing.
The BANISH 45 is made using aluminum baffles with a titanium body. In the long configuration, it weighs only 11 ounces, and it does a great job suppressing the .45 ACP, a round that is already subsonic. When setup for 9mm, it is very quiet at 36 decibels depending upon ammo choice.
Why do you want one?
The key feature to the BANISH 45 is versatility. It can handle any pistol caliber with the right setup, unless we’re talking about the .50 Desert Eagle crowd, and if you’re shooting one of those hand Howitzers, you likely don’t care about the noise. The BANISH 45 is the best option for those of us who like shooting .45 ACP and even 10mm. If you grab the two 9mm models as well as the BANISH 45, you’ll have the complete set and be ready to suppress all of your pistols.
Why suppress your pistols or PCCs
We, as humans, have five basic senses. That’s it. And with those five senses, we interact with everything in our environment. Some folks don’t have all five human senses, and some lose one or two along the way. I don’t know about you, but I find my senses to be rather important, and hearing is a big part of the joy I find in life. The bad thing, at least for me, is that a lot of the things I really enjoy are also very loud. I mean, who wants to hear Eddie Van Halen playing a guitar with the volume turned way down low? And if you’ve never heard a two-stroke engine, like a dirt bike or a chainsaw, getting the guts revved out of the motor, well, I feel sorry for you. All joking aside, hearing is very important, and suppressors make your firearms hearing safe. I have a whole blog post which you can read here that talks about the hearing safety standard of 140 decibels. The standard pistol operates at around 160-170 decibels, so you can quickly see how important one of the pistol suppressors listed above truly is.
And it’s not just your own ears that you need to be concerned about. Take your kids shooting? You should! It’s great fun and it teaches them a lot. And using suppressors protects their ears, too. Got a dog? Protect the dog’s hearing too by using a can. If you’re like me, then the dog is part of the family, and you protect family. And if the dog isn’t considered family in your household, I’m not sure we can be friends.
I heard pistols don’t shoot well with suppressors
Some brands of pistols don’t like suppressors, but that can be overcome with the proper setup. If you run into a situation where your pistol isn’t running right with a suppressor, take a look first at your ammo. Look at the way the suppressor mounts to the pistol and the piston, if necessary, to keep things functional. Most pistols with the proper set up will work great with a suppressor attached. If you find you’re running into cycling issues, take a step-by-step approach, starting with the ammo and working your way back. I have yet to see a regular pistol in a popular caliber, that can’t be suppressed.
Why suppress a pistol?
I get it. It makes sense to suppress a rifle, especially a hunting rifle, but a pistol? Are you going to carry a concealed pistol with a can on the end of it? Probably not, although you could with the right can and the right holster. I saw a conversation on the internet about this topic of suppressing pistols. The author of the original post made it sound like it wasn’t a great idea, but it actually makes total sense. (I.E. hearing is a sense, and you want to preserve it.)
Shoot your handgun in an enclosed space and then ask me if a pistol suppressor is a good idea. I’ll tell you it is, but I’ll have to either write it down for you or say it really loudly so you can hear it.
And yes, you can take a suppressor for say a .30 caliber rifle, and use it on a pistol, but it isn’t going to work as well as a dedicated pistol suppressor would. The urge to save money can be strong but add in the need for extra attachments to get it to work, and then ammo for trial and error to figure it all out.
If you use a 10mm pistol for hog hunting, a BANISH 45 suppressor is the way to go.
And I can see the argument you might make of, “Well, you work for a suppressor company so of course you say we need one.” Fair point, but in the many years I’ve been writing about the great outdoors and all the cool products out there, I don’t say great things about products that I don’t use myself. How did the old commercials go? “I’m not just the president of the Hair Club for Men; I’m also a member.” I’m not just a writer for a suppressor company; I’m also 100% convinced they are a good idea and make all shooting sports better. I am currently converting all my rifles to be suppressor ready, and many of my pistols are either getting threaded barrels or are going to get traded in for threaded new ones. And my shotguns - more on that later.
Ready?
Now that I’ve got you all hyped up talking about pistols, suppressors, freedom, dirt bikes, and Van Hallen, you now want a suppressor of your own. Getting one is easy with the simplified processes this company has in place. Let’s get started.
While many suppressors can be used on several different caliber firearms, we have some specific models that can make your shooting more enjoyable. Pick the caliber that you have in mind. If you don’t see your caliber, pick one close to it to see our recommendations.
