As with any silencer purchasing process, the best 45 suppressor largely depends on what you’re wanting to shoot it on. The great news about 45 silencers is that their versatility basically sells themselves. With the ability to run larger calibers, along with smaller calibers, 45 suppressors really do tend to be considered a jack of all trades. This blog post will be giving you our top 5 sellers to date this year in the 45 ACP suppressor category, as well as lending some insight on why they’ve become go-to’s for our customers.

1. Rugged Obsidian 45
2. SilencerCo Osprey 45
3. SilencerCo Omega 45K
4. SilencerCo Octane 45 2.0
5. Dead Air Ghost 45M

If you’re in the market for a 45 suppressor, then this list will help you know where to get started with your purchasing process - and that’s what silencer to buy, and what other customers might be looking for when they go to buy their 45 suppressor.

Before we lift off, we want to set the mood, and what better way to do that than to dive into what sets 45 ACP suppressors apart from their compadres: their user serviceability, and their use on a PCC versus handgun.

User Serviceability: It’s becoming more and more common to see that a suppressor is user serviceable, but does it matter for 45 suppressors? Well, if you look below at the nifty graph we provided, our top five list does have two silencers that aren’t user-serviceable, so for some people, it doesn’t matter, most likely due to how they clean their suppressors. Unlike rifle suppressors, pistol calibers produce far less pressure inside of a silencer. Because the pressure isn’t great enough to expel the projectile from the silencer, it can ultimately lead to an excessive buildup of carbon. While regular maintenance is advised for some pistol suppressors, depending on your cleaning methods, a user serviceable suppressor might not be necessary for you. We should mention here that user serviceability does not imply ease of cleaning. If you’re running some seriously dirty ammunition through your firearm-suppressor dream team, expect to have to clean it either by using some elbow grease, or an ultrasonic cleaner, or having to do something in the middle of those two.

PCC vs. Handgun: In our previous blog post, we covered the difference between Pistol Caliber Carbines (PCCs) and handguns. Most 45 ACP suppressors will be able to run on either pistol caliber carbines or handguns interchangeably, but be mindful of suppressor diameter and whether a clear sight picture with stock iron sights is important to you.

The provided graph shown gives you our top five selling 45 suppressors in 2020. This graph will arm you with the ability to quickly assess the similarities and differences between these top runners. Afterward, keep reading to review a more in depth analysis of why we think they managed to make their way to the top.

The Rugged Obsidian 45 is a powerhouse of a suppressor dedicated to everything pistol or rifle, with the ability to perform on some higher pressure rounds like .450 Bushmaster and .300blk subsonic. Constructed of stainless steel and aluminum, Rugged’s Obsidian has been a top choice due to its impressive balance between lightweight, and durability, while still offering modularity. The Obsidian’s design also makes this suppressor extremely user friendly and user serviceable.

Mike, one of our suppressor aficionados, simply said that the Rugged Obsidian has gained popularity because “it’s built like a tank, is configurable for length, has all the accessories you would need and is priced right.” Pulling in quite the crowd for our customers looking for a built-tough suppressor, this Rugged silencer has secured its spot as one of the most popular 45 suppressors in 2020.

Final verdict: The Rugged Obsidian 45 has a stronghold on the best 45 ACP suppressor list because of its true versatility between its modularity and caliber options. Performing well on handguns and pistol rifles, the Obsidian 45 provides suppression without obstructing your firearm’s sight picture.

The SilencerCo Osprey 45 is one of the chosen ones on our best 45 suppressor seller list because of its futuristic design, impressive noise reduction, and easy to install and uninstall locking lever. The Osprey shows that SilencerCo truly thought outside of the circle on this one, using an oblong shaped suppressor to provide as much internal suppressor volume for maximum sound suppression.

Will, one of our trusty suppressor pros, says, “the SilencerCo Osprey was popularized as a non-tubular silencer that moves the bulk of the silencer under the bore of the firearm, clearing up more room for iron sights to clear the top of the silencer.” We see customers gravitate toward the Osprey due to its impressive suppression and uniformity with its host. Additionally, the SiCo Osprey boasts a cam lever with corresponding teeth on the piston retaining ring in order to easily align the rotation of your Osprey quickly.
