45 suppressors are a jack-of-all-trades variety that can fit a wide variety of large and small calibers, handguns and pistol caliber carbines (PCCs). Choosing the best 45 suppressor will depend of course on your host firearm, as well as what you hope to do with it. This blog post will give you our top five picks from the 45 ACP suppressors with some facts and figures to back it up.

45 ACP Suppressor Considerations

A few considerations before we get started: first, user serviceability. Compared to rifle suppressors, pistol caliber suppressors don't produce much pressure inside the can, meaning that they don't automatically expel foreign matter and aren't "self cleaning." If you're shooting a high volume of dirty ammo, a user serviceable 45 suppressor will be the way to go.

Additionally, most 45 suppressors can run on either PCCs or handguns, but you should pay attention to ensure that a larger-diameter suppressor doesn't block your sights. If you only plan to shoot on a PCC, don't worry about size.

Rugged Obsidian 45

Our returning top pick is an extremely versatile modular suppressor that can take a wide range of calibers (all the way up .450 Bushmaster) for all your PCC and handgun suppression needs. It is solidly built and extremely durable — the heaviest on the list when in its full configuration.

Maintaining solid suppression in its 6.7", 10.7 oz smaller configuration, the Rugged Obsidian 45 shouldn't obstruct your handun's sights. Also thanks to smart engineering, the Obsidian 45 is extremely user friendly and user serviceable.

Final verdict: Versatile and durable, the Obsidian 45 is the gold standard of 45 suppressors, and understandably our most popular.

Dead Air Ghost 45M

Both configurations of the modular Dead Air Ghost 45M suppressor are worth bragging about. The shorter length is like a strong K silencer, while the 2.55" addition creates a high-performing full sized silencer. If you need even better performance, the Ghost is wipe-compatible. An included booster assembly makes mounting a breeze, as does a user-serviceable design.

Final verdict: Customers aren't scared of the Ghost. We say it a lot about modular suppressors, but it's especially true here: The Ghost 45M is two suppressors for one tax stamp. It's also durable and serviceable — a well-deserved member of the top five.

Griffin Revolution 45

The Griffin Revolution 45 has quite a few neat features: interchangeable front endcaps for smaller calibers (it comes with a 45 end cap, you can buy 9 or 22 front caps depending on your host firearm), anti-rotation features that keep the can from backing off in the middle of your range session, and the ability to customize with a ton of Griffin accessories.

Its partial aluminum build keeps it light weight, while delivering high levels of durability and sound reduction.

Final verdict: The Revolution 45 can hang with the best of them on versatility and durability. The fun extras and customizability are what sets it apart.

SilencerCo Omega 45K

The magic of the SilencerCo Omega 45K is its lightweight (lightest on the list) yet incredibly powerful suppression. This is made possible by a circumferentially-welded, tubeless construction, which creates the most amount of internal volume possible.

Thanks to its 1.125x28 threading, it's versatile enough to accept a wider range of SilencerCo Alpha mounts and accessories. It runs super well on PCCs and handguns alike, but beware of sight obstruction due to its 1.48" diameter.

Final verdict: Uniquely built, the Omega 45K is light, quiet and — measuring at just 6.36" — maneuverable. If compact is the silencer central to your needs, the Omega 45K is a great option.

Griffin Resistance 45

The Griffin Resistance 45 is the cool cousin of the Griffin Revolution 45. The primary difference is fixed length, which gives it a nicer price point and fantastic sound suppression. Like the Revo 45, you can try out interchangeable endcap options for suppression on a variety of calibers.

Final verdict: Designed for maximum strength and minimum blow back, the Resistance 45 is a high-performing, straightforward silencer central to your needs.
