The Best .45 Suppressors on the Market

When it comes to buying a suppressor, every person is different. They’ve each got their own checklist of things they’re looking for in a can. Because what’s most important to you might be different from what’s important to the next person, no one can really say what is truly “the best” silencer on the market.

That’s why we broke it down into some categories that we hope will help steer you towards the best .45 suppressor on the market for your specific needs.

A lot goes into picking out a suppressor. Cost, performance, length, weight, material, and more all factor into the final decision.

When it comes to picking a .45 suppressor, you have to weigh all of those variables and decide which ones are must-haves, nice-to-haves, and deal-breakers. For some people, cost will be the deciding factor. For others, it could be decibel reduction.

So, we took a look at a handful of different categories that people tend to focus on when choosing a suppressor. Hopefully, this list helps you decide what .45 suppressor will work best for you.

The BANISH 45 motto is “one suppressor, one tax stamp, many guns” and it definitely lives up to it. As the name would suggest, the BANISH 45 is designed for .45-caliber cartridges, but it isn’t limited to them.

Standard .45 ACP is, by its very nature, subsonic. This makes it a breeze to suppress and a popular choice if you want a quiet yet beefy cartridge. Of course, not everyone shoots .45 ACP. Some people prefer 9mm or even 10mm. The BANISH 45 handles both of those cartridges with ease.

With the rise of .300 Blackout as an incredibly popular caliber for AR-style pistols, we figured that the “many guns” part of the motto ought to extend to that caliber as well. As such, the BANISH 45 is capable of handling subsonic .300 Blackout rounds as well.

Whether you’re shooting the small .22LR, stepping up your game to 10mm, or anything in between, the BANISH 45 can accommodate it. Obviously, barrels on a .22 are considerably smaller than those of a 10mm, so you can choose from seven pistons with different thread options so that you can fit your BANISH 45 onto the gun barrel of your choice. (We also recommend a dedicated rimfire can, such as the BANISH 22, but you can use the BANISH 45 if you can’t swing two suppressors right now.)

Made of lightweight titanium and aluminum and able to change between two sizes means that this modular suppressor can be an incredibly compact can, while sacrificing very, very little. In fact, when shortened to 6.7” it weighs just 9.6 ounces, making it the lightest suppressor in its class.


  • Self-serviceable
  • Lightest in its class in the short configuration
  • Full auto rated


  • Price may put it out of reach for some people

Everyone has a budget, but that doesn’t mean you have to sacrifice quality for price.There are plenty of suppressors on the market that perform very well and cost relatively little. If you want a high-quality suppressor that won’t break the bank, we’d recommend you look into the Coastal Guns Ultima 45.

At just $550, it’s the most affordable option on this list. (Remember, though, that the price tag doesn’t include the mandatory $200 tax stamp for all suppressors.)

You’ve probably never heard of Coastal Guns, and that’s OK. There are a lot of “little guys” out there who make products that are just as good (and sometimes better) than the “big guys” who are household names. This is one of those situations.

Made of aluminum and stainless steel, the Ultima 45 comes in at 10.4 ounces and 9.5” in length. That puts it right in line with the other options on this list in terms of weight; it’s not the lightest, but it’s not the heaviest.

Length, however, is where it stands apart from the rest of the group. The Ultima 45 suppressor is 9.5” in length. Period. It’s a fixed-length suppressor and cannot be shortened. Now, that’s not necessarily a bad thing. A lot of suppressors are fixed length. We just wanted to point it out since all the others on this list are modular.

This suppressor utilizes a piston system called the Recoil Attenuation Device (R.A.D.). The R.A.D. is a Nielson Device designed so that the Ultima will function on semi-auto pistols. There are several different mount interfaces to accommodate a wide variety of barrel sizes and thread pitches so that you can use the Ultima 45 on a number of different guns and calibers.


  • User-serviceable
  • Price of $550 makes it affordable for almost anyone


  • Not modular in size; fixed weight and length
  • Longest suppressor on this list

The Dead Air Ghost 45M takes the prize for the shortest or most compact .45-caliber suppressor on the market.

Adding a suppressor to the end of your barrel certainly adds length and weight to your gun, and that can change the overall balance of your setup. The best way to mitigate this is to keep the suppressor as compact and lightweight as possible. Made of stainless steel, titanium, and aluminum, Dead Air has combined those metals to create a can that is light, compact, and durable.

With a removable section that’s more than two inches long, the Dead Air Ghost 45M comes in at just 6.2” in length and 9.6 ounces in its shortest configuration. At that weight, it ties with the BANISH 45 for the lightest on the list, but it pulls ahead in length. The Ghost 45M is half an inch shorter than the BANISH 45. That may not sound like much, but even the smallest measurements count when it comes to suppressors.

Dead Air’s Ghost 45M suppressor also offers the ability to use it with wipes, which enhances the suppressor’s performance by tightening down the bore aperture and increasing the number of decibels that it can reduce. This makes the Ghost 45M the smallest and quietest can in its class.


  • Removable section for modularity is more than 2” long
  • User-serviceable
  • Full auto rated


  • It’s the most expensive suppressor on this list, costing $20 more than the BANISH 45

Specs: Dead Air Ghost 45M
Caliber: .45
Weight: 9.6 oz or 12 oz
Length: 6.2” or 8.7”
Price: $969



A suppressor has to be quiet. I mean, that’s the name of the game, right? Well, if you’re looking for the quietest .45 suppressor that money can buy, look no further than the Rugged Obsidian 45.

Clocking in with a decibel reduction reading of 37 decibels, the Obsidian 45 is one quiet can! The hearing safe decibel threshold is 140 decibels, and the Obsidian 45 knocks it out of the park. In its full-length configuration, .45 ACP measures 129.3 decibels. Shooting 9mm instead? It measures just 123.7 decibels. That’s downright impressive. Period.

The construction of the Obsidian 45 is equally impressive. The body is made of aluminum and the baffles are made from stainless steel. Speaking of the baffles, they’ve got two indexing tabs on each one so that you can easily and quickly align them for proper reassembly. As a bonus, that precise alignment also helps reduce carbon buildup, making cleaning an easier task.

The use of a non-slotted piston is also a big plus for the Rugged Obsidian 45. This creates a full circumference gas seal to dramatically lower gas blowback and make shooting more fun.

If you’ve already got an Obsidian 9 and are looking to add the Obsidian 45 to your collection, I’ve got some money-saving news: it is fully compatible with Obsidian 9 accessories. Pistons, fixed mounts, fixed barrel spacers, 3 lug mounts, etc are interchangeable with the Obsidian 45.


  • Super quiet: 37 dB reduction rating
  • Rated for full-auto and belt-fed
  • Compatible with Obsidian 9 accessories


  • Heaviest on the list at 12.8 ounces, but that’s still pretty light

Specs: Rugged Obsidian 45
Caliber: .45
Weight: 10.7 oz or 12.8 oz
Length: 6.7” or 8.6”
Sound reduction: 37 dB

This is definitely one of the harder things to pin down. Trying to select the single best, or even a few best, .45-caliber suppressor hosts is hard to do. A lot of this is because of the different needs of different shooters and what they find most important.

As a result, we’re going to look at a few guns that make good suppressor hosts. They’re being chosen based on caliber (remember, lots of variety for a .45 caliber suppressor!), threaded barrel availability, and reliability of the gun, among other things.


OK, so you probably saw this one coming from a mile away. Since a .45-caliber suppressor works great with 9mm pistols, we’d be fools not to include 9mm hosts for a .45 suppressor.

Given the popularity, reliability, and variety of threaded barrels available for the Glock 17 and 19, this is an easy choice. There may not be any other pistols on the market more suited to running a suppressor than the Glock 17 and 19.


John Moses Browning’s 1911 pistol has been a mainstay for more than 100 years. Darn near every handgun company on the market makes a 1911 of some sort, and they can be had in a variety of calibers and size configurations to fit your specific needs. You can get them in .45 ACP, 9mm, and even 10mm – all of which do very well with a .45-caliber suppressor. While most don’t come with factory threaded barrels, there are plenty of aftermarket options available.


AR pistols are incredibly popular, and one of the most popular calibers for this setup is .300 Blackout. Subsonic .300 Blackout rounds are super quiet when fired from a suppressed AR pistol. Since many .45-caliber suppressors can safely handle subsonic .300 Blackout, it’s an easy addition to this list when you factor in the popularity and modularity of the host gun.

NOTE: Make sure you consult both your suppressor’s owners manual and the ammunition that you’ll be shooting to ensure that your .300 Blackout cartridges are compatible with your suppressor. Otherwise, you could damage the can and/or hurt yourself.



You really have to take a good, hard look at the guns you plan on suppressing before choosing the .45 suppressor that’s right for you.

This means not only looking at the guns and calibers that you currently own, but also ones that you might own in the future. Do they all fall within the caliber compatibility of a .45 suppressor? If yes, then it’s time to narrow down your options.

Figure out what’s most important to you: cost, weight, length, decibel reduction, etc. Once you know the most important factor in your decision, then you can start narrowing down the field of potential candidates.



It’s a tough question. Kind of like picking your favorite kid, right? (Although, let’s be honest: everyone’s got a favorite kid whether they admit it or not.)

We’re not afraid to admit that we’re partial to the BANISH 45. It is, after all, our own kid so to speak. However, there are plenty of other great options out there just like the other ones on the list above.
