Growing up, I always imagined that there was no difference between a silencer and a suppressor. They are both devices that go on the end of a gun barrel to lessen the sound of the gunshot, right? Well, it turns out that there is actually a slight difference between the two and it’s all in the name! Silencers were the original name for these devices when they were first introduced in the early 1900s. However, in 1934, the National Firearms Act was passed, and the term “silencer” was replaced with “suppressor” because it was seen as a more accurate description of what the device does.
While the terms silencer and suppressor might be used interchangeably, there are a few key differences between the two. For starters, as mentioned previously, suppressor is a more accurate term since these devices don’t completely silence a gunshot. Instead, they suppress the sound of the gunshot so that it’s less loud and less likely to cause hearing damage. Additionally, silencer is often considered to have negative connotations since it implies that the device is used for nefarious purposes. As a result, many gun enthusiasts prefer to use the term suppressor since it sounds less intimidating.
So, now that we’ve clarified what the difference is between a silencer and a suppressor, you might be wondering which one is right for your gun. The answer is that it really depends on what you’re using your gun for. If you’re using it for hunting or target shooting where noise pollution isn’t an issue, then you probably won’t need either device. However, if you’re in law enforcement or a military setting where the noise of your gun could give away your position, then a suppressor might be a good investment.
Terminology of Firearm Accessories
Firearm accessories can be confusing, and one of the biggest sources of confusion comes from the terminology used to describe each accessory. There are so many different terms used that it can be difficult to know what to call each accessory, and even harder to understand the differences between them.
However, knowing the terminology is crucial to understanding the differences between firearm accessories. Here are some of the key terms you should know when it comes to firearm accessories:
- Silencer: A device that attaches to the muzzle of a firearm and reduces the sound of the gunshot. The term “silencer” is a misnomer, as the device does not completely silence the firearm.
- Suppressor: A device that attaches to the muzzle of a firearm and reduces the sound of the gunshot. While “silencer” and “suppressor” are often used interchangeably, “suppressor” is the more accurate term.
- Muzzle brake: A device that attaches to the muzzle of a firearm and reduces recoil, allowing for more accurate and faster follow-up shots.
- Flash hider: A device that attaches to the muzzle of a firearm and reduces the visible flash that occurs when a firearm is fired. This can help prevent the shooter from being blinded by the flash in low-light situations.
- Compensator: A device that attaches to the muzzle of a firearm and reduces muzzle rise, allowing for more accurate follow-up shots.
How Silencers and Suppressors Work
Silencers and suppressors are both firearms accessories that serve the same purpose: to diminish or muffle the sound of gunshots. While the terms “silencer” and “suppressor” are often used interchangeably, there are differences between the two.
- A silencer, also called a “muffler,” is a device that is designed to completely eliminate the sound of a gunshot.
- A suppressor, on the other hand, is a device that reduces the intensity of the sound, but does not completely silence it.
- Technically, the term “silencer” is a misnomer because guns will never be entirely silent due to the mechanical noise they make.
Both silencers and suppressors function by reducing the noise created when a gun is fired through a combination of three main mechanisms:
- Baffles: These are the internal structures of the device that help to redirect and slow down the gases and sound waves that are produced when the gun is fired.
- Expansion Chambers: These are compartments that allow the rapidly expanding gases from the gunshot to dissipate, reducing the sound level emitted.
- Sound-absorbing Materials: These are materials like foam or rubber that absorb some of the sound waves created by the gunshot.
Noise Reduction Ratings (NRRs)
When evaluating silencers and suppressors, the industry standard for measuring their effectiveness is through their “Noise Reduction Rating” (NRR). This rating measures the amount of decibel(dB) reduction that the device provides.
| NRRdB | Sound Reduction | Perceived Sound Level |
|---|---|---|
| 0-10 | Minimal | No significant reduction |
| 11-20 | Slight | Barely noticeable reduction |
| 21-30 | Moderate | Somewhat quieter |
| 31-40 | High | Noticeably quieter |
| 41-50 | Very high | Substantially quieter |
| 51-60 | Extra high | Barely audible |
| 60+ | Extreme | Virtually inaudible |
Ultimately, whether to use a silencer or suppressor, and to what degree, comes down to personal preference and intended use. That said, it is important to note that the legal requirements for owning and using these devices will vary depending on your location.
Benefits of using a silencer or suppressor
There are a number of benefits to using a silencer or suppressor on a firearm, including:
- Reduced noise: Both silencers and suppressors work to reduce the noise produced by a firearm. This can be beneficial for a number of reasons – for instance, if you are hunting, you might not want to spook other animals in the area with the sound of your gunshots. Similarly, if you are at a shooting range, a suppressor can help make your shots less disruptive to other shooters.
- Reduced recoil: Sometimes, silencers or suppressors can help reduce the amount of recoil produced by a firearm. This can be especially useful for smaller or lighter-bodied shooters who might find the kickback uncomfortable or difficult to manage.
- Improved accuracy: In some cases, using a suppressor or silencer on a firearm can actually improve the accuracy of your shots. This is because the reduction in noise and recoil can help you maintain better control over your aim and decrease the likelihood of flinching or anticipation before pulling the trigger.
How do silencers and suppressors work?
Silencers and suppressors both work to reduce the noise produced by a firearm, but they do so using slightly different mechanisms. A silencer typically works by trapping and dissipating the gases that are produced when a bullet is fired, which in turn reduces the amount of noise produced. Suppressors, on the other hand, work by slowing down and cooling the gases produced by a shot, which also helps to reduce the sound. Both devices can be effective at reducing noise, but they may work better for different types of firearms or in different situations.
Legality and regulation of silencers and suppressors
The use of silencers and suppressors on firearms is heavily regulated in many countries. In the United States, for example, the National Firearms Act (NFA) requires that individuals obtain a specific license to own or use a silencer or suppressor. This license involves a background check, payment of a tax, and other requirements. Other countries may have similar regulations in place, or may prohibit the use of these devices entirely.
| Country | Legal Status of Silencers/Suppressors |
|---|---|
| United States | Regulated under the National Firearms Act (NFA). Must be licensed. |
| Canada | Legal with a license and registration. |
| United Kingdom | Prohibited. Exceptions exist for certain military and law enforcement personnel. |
| Australia | Strictly regulated. Can be owned with a license, but use is heavily restricted. |
While the use of silencers and suppressors on firearms is legal in some places, it is important to always follow local regulations and guidelines. Failure to do so can result in serious legal consequences.
Legalities of owning a silencer or suppressor in the US
When it comes to owning a firearm suppressor or silencer in the US, there are many legal aspects that gun owners should be aware of.
Firstly, the National Firearms Act (NFA) of 1934 requires all suppressors to be registered with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) and imposes a $200 tax on each purchase. This means that if you want to buy a suppressor, you need to fill out an ATF Form 4 and pay the $200 transfer tax. Once the ATF approves the application, you can take possession of the suppressor.
Secondly, the NFA also dictates that suppressors can only be used for lawful purposes, such as hunting or shooting at a range. Using a suppressor to commit a crime can result in severe legal consequences.
Thirdly, it is essential to note that the legality of owning a suppressor or silencer varies from state to state. Some states, such as California, do not allow the ownership of suppressors at all, while others require additional permits and licenses beyond the federal NFA requirements.
- As of July 2021, the following 42 states permit civilians to own suppressors: Alabama, Alaska, Arizona, Arkansas, Colorado, Connecticut, Florida, Georgia, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Mexico, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.
- The following states, along with the District of Columbia, prohibit civilian ownership of suppressors: California, Delaware, Hawaii, Illinois, Massachusetts, New Jersey, New York, and Vermont.
- Lastly, Iowa and Minnesota require specific permits to own a suppressor beyond the federal NFA tax stamp.
It is always crucial to check your state and local laws regarding firearms suppressor ownership before purchasing or using one. Even if owning a suppressor is legal in your state, it is essential to note that some localities may have additional restrictions or regulations regarding their ownership or use.

Differences in sound reduction between silencers and suppressors
When it comes to sound reduction, silencers and suppressors are often used interchangeably. However, there are some differences in the way they reduce noise.
- Silencers: These are designed to reduce the noise of a gunshot by capturing the expanding gases that are created when a bullet is fired. The gases are trapped in the silencer and are allowed to expand, cool down, and ultimately dissipate through a series of chambers. The result is a quieter shot that can be up to 40 decibels lower than an unsuppressed shot.
- Suppressors: Suppressors work by reducing the speed and pressure of the gases that are released when a bullet is fired. This is done by allowing the gases to expand through a series of baffles or chambers before they exit the suppressor. While suppressors can also reduce the sound of a gunshot, they are not as effective as silencers. Typically, suppressors can reduce the sound of a gunshot by 20 to 30 decibels.
It’s important to note that both silencers and suppressors only reduce the noise of a gunshot, not eliminate it completely. Additionally, the level of sound reduction can vary depending on the caliber of the firearm and the type of ammunition being used.
To give you a better idea of how silencers and suppressors stack up against each other in terms of sound reduction, take a look at the table below:
| Firearm | Unsuppressed | Silenced | Suppressed |
|---|---|---|---|
| 9mm Handgun | 158 decibels | 128 decibels | 138 decibels |
| .223/5.56 Rifle | 165-170 decibels | 130-135 decibels | 140-145 decibels |
| .308 Rifle | 169-174 decibels | 135-140 decibels | 145-150 decibels |
As you can see, silencers are generally more effective at reducing noise levels than suppressors. However, both devices can make a significant difference in the sound of a gunshot, which can be crucial in certain situations such as hunting or tactical operations where noise reduction is important.
Variations in design between silencers and suppressors
Although the terms silencer and suppressor are often used interchangeably, there are some differences in their design that can affect their performance and effectiveness. Here are some of the main variations in design between silencers and suppressors:
- Shape: Silencers tend to be cylindrical, with a wider diameter than suppressors. Suppressors, on the other hand, often have a more streamlined shape, which can improve their portability and make them more discreet.
- Baffles: Both silencers and suppressors use baffles to slow down and cool the gases that are released when a firearm is discharged. However, the number and shape of the baffles can vary widely between different designs. Some silencers have many small baffles, while others have fewer, larger baffles. Suppressors may use a mix of different baffle shapes and sizes to improve the performance of the device.
- Materials: Silencers and suppressors can be made from a range of different materials, including aluminum, titanium, and stainless steel. The type of material used can affect the weight, durability, and cost of the device.
- Mounting: The way that a silencer or suppressor attaches to a firearm can also vary. Some models screw onto the barrel of the gun, while others slide over the barrel and are secured in place with a locking mechanism. Some suppressors also use quick-detach systems that allow them to be easily added or removed from a firearm.
- Performance: While both silencers and suppressors are designed to reduce the noise and recoil of a firearm, they can have different levels of effectiveness depending on the design. Some suppressors may do a better job of reducing sound levels, while others may offer better recoil reduction or be more compact and portable.
- Regulation: In some countries, there may be different regulations governing the use of silencers and suppressors. For example, in the United States, silencers are regulated by the National Firearms Act and require a special tax stamp to purchase.
Overall, the differences in design between silencers and suppressors can affect the performance, portability, and cost of each device. It’s important to understand these variations when choosing a silencer or suppressor for your firearm, and to ensure that you comply with any relevant regulations or restrictions in your area.
The History of Silencers and Suppressors in Warfare and Hunting
Throughout history, humans have sought ways to make their weapons quieter in order to gain a strategic advantage. The earliest forms of silencers date back to the late 1800s when Hiram Percy Maxim developed a device to reduce the noise of firearms. Back then, silencers were primarily used for hunting, as poaching was a major issue, and hunters needed to be discreet to avoid detection by game wardens. However, with the outbreak of World War I, countries around the world began exploring the use of silencers for military purposes as well.
- In the early days of silencers, they were primarily used for small-caliber firearms such as handguns and rifles. They were also relatively uncommon due to the high cost of production.
- However, by World War II, silencers had become more widespread, with various nations developing their own versions. The German MP-40 submachine gun, for instance, had a detachable suppressor that reduced the noise of gunfire by 20-30 decibels.
- The advent of the Cold War brought about even more advancements in suppressor technology. In the United States, the CIA used silencers on their 22-caliber high standard pistols during covert operations in the 1960s.
While silencers and suppressors were originally designed for military and hunting applications, they have become increasingly popular among recreational shooters in recent years. In the United States, they are legal for civilians to own in most states (although there are still restrictions in some places), and many gun owners choose to use them in order to protect their hearing and reduce noise pollution at shooting ranges.
However, there are still many misconceptions about silencers and suppressors. Many people believe that they completely silence the sound of a gunshot, which is simply not true. Even the most effective suppressors will only reduce the noise by a certain number of decibels, and they will still produce a significant amount of noise. This is why the term “suppressor” is more accurate than “silencer”.
| Common Misconceptions About Silencers/Suppressors: | Reality: |
|---|---|
| Silencers make guns completely silent. | Silencers only reduce noise by a certain number of decibels, and they still produce a significant amount of noise. |
| Silencers are illegal. | Silencers are legal to own in most states, although there are still restrictions in some places. |
| Silencers are only for assassins and criminals. | Many hunters, military personnel, and recreational shooters use silencers to protect their hearing and reduce noise pollution. |
As technology continues to evolve, it is likely that we will see even more advancements in suppressor technology in the coming years. Whether you are a hunter, military personnel, or a recreational shooter, owning a quality suppressor can help protect your hearing and make shooting a more enjoyable experience overall.
