Best .45 ACP Suppressors for Pistols and PCC Reviewed

Getting the right suppressor for your .45 ACP firearm can transform your shooting experience. The .45 ACP round has been an American favorite since 1911, famous for its stopping power and manageable recoil. When paired with a quality suppressor, this iconic caliber becomes even more enjoyable to shoot.

Suppressors do more than just reduce noise, they also cut down on recoil, can improve accuracy, and make shooting more comfortable for everyone around. These days, modular suppressors that work with multiple calibers are becoming increasingly popular, giving gun owners more bang for their buck.

In this article, we'll break down the top seven .45 ACP suppressors on the market today. You'll get the full scoop on each one.

Why Trust This List?

All suppressors in this roundup were selected based on:

• Sound suppression performance
• Weight and balance characteristics on both pistols and PCCs
• Modularity options and caliber compatibility
• Real-world applications (target shooting, home defense, hunting)

Our selections are based on the Pro-Armory team's combined experience across military service, competitive shooting, and years working in gun shops. Along with our experience we also combined it with detailed online research and analysis.

We also considered feedback and commentary from actual users and respected voices in the firearms community to bring you informed and practical insights on each product.

What to Look for in a .45 ACP Suppressor

Sound suppression: Decibel ratings matter! Look for suppressors that bring the sound level below 140dB, which is the threshold for hearing safety.

Weight & Size: This is super important, especially for handguns. A heavy suppressor can make your pistol front-heavy and harder to aim.

Modularity: Many modern suppressors can be configured in different lengths. Short configurations work great for compact setups, longer ones offer better sound suppression.

Materials: Titanium offers the best strength-to-weight ratio but costs more. Stainless steel is very durable but heavier. Aluminum is lightweight but less heat-resistant.

Ease of cleaning: User-serviceable suppressors can be taken apart for cleaning, which is essential if you plan to shoot dirty ammunition or rimfire rounds.

Mounting systems: Direct-thread is simple but takes time to attach/detach. Quick-detach systems are faster but add weight and complexity.

Multi-caliber support: Getting a suppressor that handles multiple calibers saves you money in the long run. Many .45 suppressors can also handle 9mm, .40 S&W, and even some rifle calibers.

Price & NFA Factors: Beyond the suppressor cost, factor in the $200 tax stamp and transfer process. A gun trust can make ownership easier in the future.

One of the advantages of .45 ACP is that most loads are naturally subsonic, making it an excellent candidate for suppression. But it isn’t the only handgun caliber where suppressors shine. For shooters interested in smaller calibers, our review of the best 9mm suppressors highlights the top options for pistols and pistol-caliber carbines.

SilencerCo Osprey 45 2.0

A unique polygonal suppressor designed specifically for pistols, the Osprey 45 2.0 is known for its offset shape, allowing shooters to use standard-height sights. It provides excellent sound reduction for .45 ACP handguns and PCCs without adding excessive weight or bulk. Designed for convenience, it locks into position with a push-button system for consistent alignment.

The Osprey stands out from the crowd with its rectangular profile that keeps most of the suppressor's bulk below your sight line. This innovative design means you won't need to swap out your factory sights for taller ones—a common requirement with traditional round suppressors.

If you own both .45 ACP handguns and big bore rifles, this suppressor offers amazing value despite its higher price tag.

CGS Nautilus

The CGS Nautilus works like a bigger version of the Mod-9, but it's made for .45 ACP guns. Even though it's big enough to handle powerful shots, it stays light. Most of its weight sits near the back, so your gun doesn't feel front-heavy when you hold it.

The piston has special cuts that stop that loud first shot noise. The new Orion baffles inside make your shots extra quiet.

Final Thoughts: Which .45 Suppressor Should You Get?

Choosing the right .45 ACP suppressor comes down to your specific needs. Each option has its strengths.

The BANISH 45 and Hybrid 46M excel in their ability to work across many different firearms. It  makes them excellent choices if you have a diverse collection. The SilencerCo Osprey remains the king of low-profile designs, letting you keep your standard sights. For those who demand maximum toughness, the Rugged Obsidian 45 stands as the tank of the group.

Budget-conscious buyers should take a serious look at the CGS Nautilus, which delivers great performance at a lower price point. Big bore enthusiasts can't go wrong with the Hybrid 46 DT, especially if they already own .45-70 or similar calibers.

Remember that suppressors are long-term investments. With the tax stamp soon dropping to $0, the waiting period still makes it worth spending a bit more upfront to get exactly what you need . Consider setting up a gun trust before purchasing—it makes sharing your suppressor with family members much easier and helps with future transfers.

When all is said and done, any of these seven suppressors will serve you well. The best choice depends on which firearms you'll use most often and how you prioritize factors like weight, sound reduction, and price.

Many shooters today also look for suppressors that can cover multiple platforms, not just handguns. If your interests extend to rifles, especially the AR platform, don’t miss our guide to the top AR-15 suppressors for 5.56 and multi-caliber use.

Frequently Asked Questions

Can I use a .45 ACP suppressor on a 9mm pistol?

Yes, you can use a .45 ACP suppressor on a 9mm pistol. The larger diameter of the .45 suppressor can accommodate the smaller 9mm rounds. You'll get good sound suppression, though a dedicated 9mm can might be slightly more efficient due to its tighter bore.

Do I need subsonic ammunition when using a .45 ACP suppressor?

One advantage of .45 ACP is that standard ammunition is already subsonic in most cases. This means you don't need to buy special subsonic ammo—the standard 230-grain loads are naturally below the speed of sound and work great with suppressors.

How often should I clean my .45 ACP suppressor?

For sealed suppressors like the Osprey or Hybrid models, cleaning isn't possible or necessary for centerfire calibers. For user-serviceable suppressors like the BANISH 45 or Rugged Obsidian, clean them after approximately 500-1000 rounds. If you shoot rimfire through them, clean more frequently—every 200-300 rounds.

Can I leave my suppressor attached to my home defense gun?

Yes, many people keep suppressors mounted on home defense firearms. The benefits include reduced noise (protecting your hearing in an emergency) and better control. Just ensure the added length doesn't compromise your ability to maneuver in tight spaces.

How long does the NFA approval process take for a suppressor?

Currently, approval times vary from 60-150 days for eForm 4 applications with a trust. Paper Form 4 applications typically take 7-12 months. Using a service like Silencer Central can help streamline this process.

Are titanium suppressors better than stainless steel ones?

Not necessarily better—just different. Titanium suppressors like the BANISH 45 are significantly lighter but more expensive. Stainless steel suppressors like the Rugged Obsidian are heavier but often more durable against extreme use. Choose based on your priority: weight savings or maximum durability.
