Can You Put a Suppressor on Any Firearm?

How to know if your firearm is suppressor ready

Suppressors, often referred to as “silencers,” have grown in popularity among civilian firearm enthusiasts and professionals alike. These devices are used to reduce the noise, muzzle flash, and even sometimes recoil produced when a firearm is discharged. While there is a lot of interest around suppressors, questions about their compatibility with different firearms and their legal standing frequently arise. 

The answer to whether you can attach a suppressor to any firearm is not straightforward. Several factors need to be considered, such as the type of firearm, suppressor compatibility, and legal restrictions.

Understanding a “Suppressor”is not a “Silencer”

One of the most common misconceptions about suppressors is that they are called "silencers." This term can be traced back to the early 20th century, when Hiram Percy Maxim patented the first device intended to reduce the noise of a firearm, which he named the Maxim Silencer. However, the term "silencer" is somewhat misleading.

A suppressor doesn’t actually silence a firearm. While it reduces the noise significantly, it does not eliminate it completely. Even with a suppressor, gunfire can still be heard, though it is much quieter than without one. The name "suppressor" is more accurate because it describes the function of reducing or "suppressing" the sound rather than eliminating it.

The noise of a gunshot comes from three sources: the explosive discharge of gasses from the muzzle, the sonic boom caused by the bullet breaking the sound barrier, and the mechanical noise of the firearm’s action. A suppressor only addresses the first of these, making the term "silencer" technically incorrect.

The goal of a suppressor is to slow down and cool the gasses that escape when a bullet is fired. This action reduces the loud crack associated with a gunshot. However, in most cases, especially with supersonic ammunition, the bullet breaking the sound barrier will still make a distinct noise. Subsonic ammunition, which stays below the speed of sound, can make the suppressed shot much quieter, but even then, the firearm is not completely silent. This is why the term "suppressor" is preferred among industry professionals, as it more accurately reflects the device's function.

Types of Firearms and Suppressor Compatibility

Now that we understand the terminology, let's explore which types of firearms can accommodate suppressors. Not all firearms can easily accept a suppressor, and some may require specific modifications. 

Let’s take a look.

1. Handguns

Many modern handguns, especially semi-automatic pistols, can be outfitted with suppressors. However, for a suppressor to be attached, the firearm must have a threaded barrel. Threaded barrels allow the suppressor to be screwed onto the firearm securely. While some handguns come equipped with threaded barrels from the factory, others will need aftermarket parts or professional threading. Popular handguns like the Glock 19, Sig Sauer P320, and HK VP9 often have factory ready threaded barrel options, making them suppressor-ready.

When attaching a suppressor to a handgun, it’s important to consider how it will affect the gun’s performance. The additional weight on the barrel can change the firearm's balance and may impact how reliably it cycles, particularly for semi-automatics. However, suppressors on handguns are highly effective at reducing noise and are widely used in tactical, sporting, and self-defense applications.

2. Rifles

Rifles are among the most common firearms to be fitted with suppressors. Similar to handguns, rifles need a threaded barrel to accommodate a suppressor. Most tactical and modern sporting rifles, such as the AR-15, are designed with suppressor use in mind and often come with threaded barrels. Rifles can also be fitted with caliber-specific suppressors, with the most versatile suppressors being able to handle multiple calibers, such as a .30-caliber suppressor used on both .308 and 5.56 NATO rifles.

One of the key benefits of suppressing a rifle is the reduction in recoil and noise. Rifles typically produce louder gunshots than handguns due to their higher velocity and larger calibers. Suppressors make shooting rifles more comfortable by reducing the sharpness of the gunshot. This is especially useful for hunters who want to protect their hearing without disturbing wildlife as much, or for competitive shooters aiming to minimize distractions.

3. Shotguns

Suppressors for shotguns are less common but are still available. Suppressing a shotgun presents unique challenges due to the larger bore size and the spread of the shot. Shotgun suppressors are typically bulkier and longer than those used for rifles and handguns. While they can reduce the noise of a shotgun blast, the sound reduction is not as pronounced as it is for rifles or handguns.

Shotgun suppressors are primarily used in niche situations, such as by hunters who want to reduce noise while in the field. The suppressor can help prevent scaring off game while still protecting the shooter’s hearing. However, due to the complexities involved in shotgun suppression, they are not as commonly seen as suppressors for other firearms.

4. Revolvers

Revolvers, due to their design, are generally not good candidates for suppressors (despite what Call of Duty may say). The gap between the cylinder and the barrel allows gas to escape, making it difficult for a suppressor to significantly reduce the noise. However, there are exceptions, such as the Nagant M1895 revolver, which has a gas-sealing mechanism that makes it compatible with a suppressor. For most revolvers, though, a suppressor won’t be effective due to the inherent design limitations.

5. Air Guns

Air guns, including air rifles and air pistols, are often quieter than traditional firearms, but they can still produce a noticeable pop when fired, especially with high-powered models. Many air guns can accommodate suppressors, and some are even built with integrated suppressors or moderators. These suppressors work similarly to those on firearms by dampening the sound of the compressed air released when the pellet or BB is fired. Suppressing an air gun can be particularly advantageous for target practice, pest control, or backyard shooting, where noise reduction is a priority.

6. Muzzleloaders

Muzzleloaders, which are loaded from the front of the barrel, present unique challenges when it comes to using suppressors. Since muzzleloaders use black powder or similar propellants, the explosion creates a large amount of gas, soot, and residue that can quickly clog a suppressor. Additionally, attaching a suppressor to a muzzleloader often requires a specially threaded barrel, which is not standard for most traditional designs. Although muzzleloader suppressors are rare, a few manufacturers produce them for modern inline muzzleloaders, where the suppressor can help reduce recoil and noise during hunting or shooting. However, maintenance becomes more complicated, as the suppressor must be cleaned frequently to prevent fouling from the black powder residue.

Why Would You Need a Suppressor?

There are several practical reasons to use a suppressor, beyond just reducing the noise of gunfire.

1. Hearing Protection

Obviously, one of the most significant benefits of using a suppressor is the protection it provides for your hearing. Even with ear protection, the loud crack of a gunshot can damage hearing over time. A suppressor reduces the decibel level of gunfire, which can make shooting more comfortable and safer for your ears (though it is still recommended to wear your ear pro when sending rounds down range). This is particularly useful in enclosed spaces or at indoor ranges, where the noise can be amplified by walls and ceilings.

2. Reduced Recoil

Suppressors can also help reduce the felt recoil of a firearm. The device traps and redirects some of the gasses expelled during firing, which can lessen the kickback. This makes the firearm easier to control, especially when shooting larger calibers or automatic rifles. Reduced recoil can lead to better accuracy, particularly in rapid-fire situations, and is beneficial for both beginners and experienced shooters.

3. Minimized Muzzle Flash

In low-light conditions, muzzle flash can be blinding and disorienting for the shooter. Suppressors help to minimize this flash by containing and cooling the gases before they exit the firearm. This makes suppressors valuable in tactical situations, hunting, or any scenario where preserving night vision is crucial.

4. Less Disturbance

Suppressors are also beneficial in reducing noise pollution. Whether you're shooting on private property or in a rural area, the loud sound of gunfire can be disruptive to neighbors and wildlife. Suppressed firearms are quieter, making them more considerate for those around you.

Legal Considerations

In the United States, suppressors are regulated under the National Firearms Act (NFA) of 1934. This means that while suppressors are legal to own, they require a special tax stamp, registration, and background check. The process involves filling out ATF Form 4, paying a $200 tax, and waiting for approval, which can take several months.

However, suppressor ownership is not legal in every state. States like California, New York, and New Jersey ban civilian suppressor ownership, while others like Texas and Florida permit it under federal regulations. Always check your local and state laws before purchasing or using a suppressor.
