.45 ACP is an extremely common pistol cartridge. It is widely used as a self defense round, due to its larger size and great ballistics. However, with most popular calibers comes a wide variety of available suppressors. In that sense, .45 ACP is no different. There are quite a few suppressors to choose from, which can make narrowing the list down difficult.
In this article, we will go over some of the absolute best .45 ACP suppressors available. However, before we get into the suppressors, make sure you are considering a few key features while shopping. For a handgun suppressor, some of these features are the following:
- Size: If this suppressor is for a carry weapon, size and weight will be an important factor to you. How much bulk are you willing to add to your weapon?
- Affordability: It shouldn’t be a surprise, but suppressors are rather expensive. Regardless of how you look at it, price will be a factor in the buying process.
- Noise reduction: After all, this is the point of the suppressor to begin with. How much noise will the suppressor actually reduce?
- Durability: Since .45 ACP is sometimes used as a hunting sidearm, keep in mind that you may need a highly durable suppressor to be used on your weapon.
With these features in mind, along with a handful of others, you will be able to make a better decision. Generally speaking, you will be able to weigh which factors are more important to you based on your expected use of the weapon. However, we will make a few recommendations throughout the article.
Top Five 45 ACP Suppressors
Excellent noise reduction
Best suppressor for concealed carry
If you don't have much time, I have some quick suggestions for you:
- When it comes to everyday carry, a small and lightweight suppressor is going to be very important. Some choices for you would be the Sig Sauer SRD45 and the Gemtech GM-45.
- When looking for a ranger suppressor, the most important feature is going to be the noise reduction. For this purpose, the SilencerCo Hybrid is the best option for you.
- For hunting, durability is key, and pretty much every suppressor on this list would be good for you. However, a lighter weight means you have to carry less, so that is something else to keep in mind.
- If you are looking for a suppressor for multiple uses, be sure to check out the Advanced Armament Ti-Rant. The modularity of this suppressor makes it an extremely interesting option for most people.
They Hybrid 46 from SilencerCo is an extremely versatile suppressor. You can use it on pistols from 9mm to .45 ACP and rifles from 5.56 to .45-70. As you can see, this gives you an extremely wide array of weapons you can use this suppressor on.
It measures 7.8 inches long, 1.57 inches in diameter, and weighs in at 17.3 ounces. As you will see, this is the heaviest suppressor on our list. While it is not all that long, it is large in diameter and pretty heavy. It’s made of titanium and stainless steel.
However, what sets this suppressor apart is how much noise reduction it is capable of. This reduces the noise of each shot by around 35 decibels.
This is the most noise reduction on our list, and helps to make up for the added length.
The other pros of this suppressor are the durability and the overall quality. Thanks to the titanium and stainless steel construction, this suppressor is extremely durable. The quality is exactly what you expect it to be from SilencerCo. They are one of the most respected suppressor brands in the world.
The cons of this suppressor are the weight and the price. As we already mentioned, this is one of the largest suppressors on our list. The price also makes it the most expensive on our list. However, these cons are outshined by the excellent noise reduction.

The Ti-Rant from Advanced Armament is an extremely unique suppressor.
When you buy this suppressor, you get a tool that can be used in two different configurations, all covered under one tax stamp.
This suppressor can either be used at its full length of 9 inches, or with a very quick change, the suppressor can be used in a shortened capacity at 9 inches long. When using the full size, it weighs 13 ounces, and when using the compact option, it weighs 11.3 ounces. As you can see, this suppressor is significantly lighter, while also capable of being shorter.
When using the full length, the noise reduction equates to 33 decibels when used dry and 41 decibels when used wet. The compact size reduces the noise by 21 decibels dry and 28 decibels wet. In terms of noise reduction, this suppressor performs well.
The other pros of this suppressor are the multi-caliber uses and durable construction. The suppressor can be used with 9mm and .40 Smith & Wesson, and also .300 Blackout with an adaptor. This suppressor is made of titanium and aluminum, which makes it decently durable.
The cons of this suppressor are that the pistons are sold separately.
Due to its modularity and versatility, this suppressor is pretty widely applicable. In the compact configuration, this would make a good everyday carry suppressor, while the full configuration would be great for range shooting. All in all, this suppressor is great for many uses.
- Modularity. Use it either compact or full length.

The Osprey from SilencerCo is another excellent offering from the manufacturer. There are actually two different versions of this suppressor, the Osprey 45 and the Osprey 45K. They are both a distinct rounded corner square shape.
The Osprey 45 is the full size one. It measures 8.06 inches long and weighs 11.1 ounces. It reduces the noise of .45 ACP by about 33 decibels.
The 45K is much more compact. It measures 6.41 inches long and weighs 8 ounces. In terms of noise reduction, it reduces the shot by about 27 decibels.
When comparing this suppressor to the previous one, you can see that it performs slightly better as both the full size and compact options. However, the unfortunate thing is that these are two completely separate suppressors, while that is only one suppressor that can be used multiple ways.
The pros of this suppressor are the overall quality, durability, and relatively small size.
As has been common with SilencerCo suppressors, this suppressor is of the highest quality. It is also worth mentioning that the pistons are sold separately.
