Let’s get this conversation started with a fun fact.

Silencers and suppressors are the same thing; however, silencer is the legal name for the same device, whilst suppressor is a commonly used phrase. Silencers do not completely quiet the weapon, but they do minimize the gunshot noise and recoil.

A silencer is often intended to reduce the amount of noise and flash produced by a weapon during actions such as home defense, hunting, range shooting, or usage in noise-sensitive regions.

We’ll learn about the advantages of adding a suppressor to a Glock since it’s one of the most often used pistols for all of these applications. We’ll also look at some of the best suppressors for Glock pistols on the market. As a last note, we’ve included a brief FAQ section.

What to Look for in a Glock Silencer

When it comes to choosing the perfect silencer for your Glock, there are a few things to keep in mind.

These characteristics define what makes a good Glock suppressor and what you should look for when purchasing one.

Material

The choice of material utilized to make a silencer has a direct impact on its durability. The pressure of expanding gasses is controlled by a silencer, which reduces sound.

A silencer comprised of less effective metals, on the other hand, might melt or fracture with repeated auto firing, therefore it’s best to go with a more robust and trustworthy silencer. It’s most likely one composed of hardened alloys.

Caliber

Silencers for various calibers are not interchangeable. Large caliber silencers may still be used on small caliber guns, but this isn’t practical and necessitates various mounting techniques.

As a result, always choose a suppressor that matches the caliber of your Glock.

Installation of a silencer

Thread-pitched or quick-detach suppressors are available. Take note of your Glock’s muzzle thread pitch so you may need to purchase a suppressor with appropriate threading.

If you want to easily switch your silencer between firearms, a fast detach type silencer is a good option.

Adaptability

The primary function of a silencer is to reduce sound and recoil. The sound of a 9mm handgun is about 160 dB. The sound level that is safe for your hearing is 85 dB.

As a result, installing a silencer to your Glock is a wise idea. You should also get a silencer with considerable noise and recoil reduction, as well as maybe pleasing looks.

POI 

The acronym POI stands for “Point of Impact.” It’s the change in the weapon’s aiming position when you attach a suppressor to the barrel. Consider purchasing a suppressor with a little point of impact shift.

Review: The 5 Best Glock Suppressors

Now that we’ve covered the basics of purchasing a suppressor, let’s look at some of the greatest Glock suppressors available.

These silencers were chosen based on their features, our reviews and favorable consumer feedback from the internet community.

The Best Glock Silencer & Suppressor overall: GEMTECH – BLACKSIDE SUPPRESSORS

The Best Glock Silencer & Suppressor overall: GEMTECH - BLACKSIDE SUPPRESSORS


Pros

  • Best noise reduction
  • Easy cleaning
  • Simple Installation

Cons

  • Expensive (worth it for the quality though)

Gemtech came up with a unique suppressor design, thus it had to be included on the list. The BLACKSIDE SUPPRESSOR is composed of 7075 aluminum, a high-quality and long-lasting material. The silencer features a cylindrical body with Matte Black Cerakote with Reduced Visual-IR Signature on the lid and a black matte anodized finish over the core.

The BLACKSIDE SUPPRESSOR is made up of two tubes, with the inner cylinder being grilled and the outer housing cylinder being sealed on the outside. For appropriate cleaning and maintenance of the silencer, these tubes may be removed from one another. This is a special function that you won’t find on most other silencers.

This silencer takes 9mm, .45 ACP, .40 S&W, and 10mm rounds, allowing it to be mounted on a variety of pistols with the suitable threading pitch (5/8-28). The silencer has been proven to lower the noise level of your Glock by anywhere from 21 to 35 decibels, which is a substantial decrease.

It just adds 5.5 ounces to your Glock’s weight, so it’s not a major weight gain. Mounting is not a problem since all BLACKSIDE SUPPRESSORS come with a standard .578-28 piston. Because the silencer is full-auto rated, it can be used for long shooting sessions.

Verdict

The GEMTECH BLACKSIDE suppressor is a lightweight and easy-to-clean noise reduction device for your Glock.

The silencer is simple to install and works with a wide range of calibers. The noise reduction it delivers is one of, if not THE best on the market.

2nd Best Glock Silencer & Suppressor: SILENCERCO – OMEGA SILENCER

2nd Best Glock Silencer & Suppressor: SILENCERCO - OMEGA SILENCER


Pros

  • Great performance & Sturdy design
  • Versatile, fits on many guns
  • Easy to install

Cons

  • None

The Omega silencer is another Silencerco product on our blog. It has a cylindrical shape and can be put on the muzzle of your Glock with the help of a mount included in the box. A combination of Stellite and stainless steel was used to create the silencer. As a result, the silencer is long-lasting and dependable.

The silencer is blast erosion-resistant and certified for full-automatic operation, so you can see how durable these silencers are. For the 9mm and 45ACP calibers, the silencer comes in a few distinct variants. Furthermore, these silencers can be swapped out and placed on 300 AAC Blackout rifles, providing excellent sound suppression for both supersonic and subsonic rounds.

The silencer features a compact design with a small length and diameter, making it easy to carry on your Glock. The suppressor reduces the amount of noise produced by your Glock. Its small size means it won’t go in the way of your handgun’s sights. You can also utilize reflex sights, tac lights, and lasers with it.

The silencer is known to lower the blast noise of a 9mm rifle to 131.5 decibels and a 40 S&W rifle to 136.2 decibels, which are both considerable reductions. It can be placed to pistols, rifles, and submachine guns, making it very flexible.

Verdict

For your Glock, the Omega Silencer is a lightweight and long-lasting noise reduction option.

The silencer is compact enough to be carried easily and is also dependable due to its full-auto rating.

3rd Best Glock Silencer & Suppressor: SILENCERCO – OSPREY .45 SUPPRESSOR

Best Glock Silencer & Suppressor: SILENCERCO - OSPREY .45 SUPPRESSOR


Pros

  • Very short in length, can be holstered
  • Unique look
  • Good noise reduction & Easy installation

Cons

  • Could hinder Tac-light Field of View

When it comes to silencer manufacture, Silencerco has its special competence. The same may be said about Osprey, a unique suppressor model.

The silencer is composed of 6061 T6 aluminum, which is the same material used to make receivers and other tough gun components. This attests to the suppressor’s longevity and dependability.

The silencer is developed primarily for the .45 ACP caliber, although it may also be used with 40 S&W and 9mm Glocks. When compared to the regular sound of a 9mm Glock, the suppressor decreases noise levels to 132.5 dB, a nearly 25% drop.

The suppressor’s body is eccentric, which means the bore does not go through the tube’s centre. This function aids in maintaining the silencer’s majority of pieces below the bore’s centerline, preserving your weapon’s POI. This also avoids the POI concerns that cylindrical silencers have, allowing you to utilize your weapon’s factory sights or any alternative sights with ease.

In comparison to round silencers, the Osprey Suppressor accomplishes its goal in a little amount of volume. When compared to a cylindrical silencer, it has 30% more internal capacity. The silencer may be readily holstered into any open-bottom holster since it is designed to look like a Glock slide.

It also incorporates a Quick Disconnect (QD) system that enables you to swiftly remove it when not in use. All you have to do now is thread the mount onto your Glock barrel. The suppressor is elegant and compatible with a wide range of firearms.

Verdict

The Osprey 45 Suppressor has a clever design that increases volume while maintaining POI.

The silencer is long-lasting and simple to install. It may be used for target shooting, home protection, and even hunting.

Is it legal to use gun silencers? – 101 Regulation

In the vast majority of states, yes. In the United States of America, silencers for weapons are permitted in 42 of the 50 states. That does not, however, mean that you can purchase it on an internet sale and expect it to arrive within a week. The legislation strictly regulates the sale and possession of silencers.

Best Glock Silencers & Suppressors

Silencers are similar to receivers in that they have a unique serial number for registration. To purchase a silencer, you must pay a $200 tax through a revenue stamp. Not only that, but purchasing a silencer requires a criminal background check.

The National Firearms Act (NFA) branch of the BATFE is responsible for the ownership of silencers (Bureau of Alcohol, Tobacco, Firearms, and Explosives).

Illegally possessing silencers is a severe offense that may result in a court sentence of up to 30 years in jail for the offender. Local restrictions governing the use of silencers exist in several states and municipalities.

Connecticut and Vermont, for example, allow the ownership of silencers but prohibit hunting with them.

How to install a Glock Suppressor

Note: Before doing any kind of servicing or maintenance on your Glock, be sure it’s safe. To double-check, remove the magazine and pull the slide.

It’s not difficult to attach a suppressor to a Glock, particularly if you know how to dismantle and clean it. But, before we get started, keep in mind that you’ll need a muzzle threaded barrel to add a suppressor. Because factory Glock barrels lack this feature, you may need to purchase a replacement one.

Best Glock Silencers & Suppressors

To remove the slide, cock the action back and press the takedown leverage pin. When you’re finished, carefully remove the recoil spring from the slide and lay it aside. Pull out the barrel now, and if it’s not threaded, replace it. Place the barrel in the slide, reposition the recoil spring, and use the takedown pin to secure the slide to the receiver.

Next, place the silencer on the threaded end of the barrel and screw it all the way down. Make sure it’s correctly tightened, but not too tight.

To examine the mechanism, cock the slide all the way back and pull the Glock trigger. Check the POI and whether the sights are aligned correctly by aiming the Glock in a safe direction.

Final thoughts

The main goal of adding a suppressor to a Glock is to lower the amount of noise produced when a shot is fired.

Suppressors have been reported to lower noise by about 20%, which is a useful characteristic for both general and tactical scenarios.

A good suppressor should be long-lasting, dependable, simple to install and maintain, and should not interfere with the POI.

Question people often ask about silencers

Your mind may be racing with questions for which you want immediate answers.

Best Glock Silencers & Suppressors

We’ve put up a quick FAQ section to aid you with any basic questions you may have about this subject, so you can feed your thirst for knowledge.

Is a Threaded Barrel required for a Silencer?

Yes, absolutely. Because the bullet emerges from the muzzle end, a threaded barrel is necessary to screw on the threads of the Best Glock Silencers & Suppressors.

This is a more solid and dependable configuration. Suppressors with QD mounts, which can be screwed into a threaded barrel for rapid attachment and removal, are available.

What is the function of a Silencer?

To grasp this, you must first comprehend what causes the noise. When you fire a bullet, the hot gasses produced by gunpowder combustion expand fast, pushing the bullet out of the barrel.

The sound is created as these gasses depart the barrel and shift from very high pressure to very low pressure. The additional space provided by a barrel allows for a more gradual and efficient transition, resulting in less noise.

Are gun Silencers effective?

They do, in fact. But not in the manner that Hollywood portrays them. When you shoot your weapon with the suppressor on, you won’t hear a “whip” sound.

Shooting a 9mm Glock, for example, produces a sound of roughly 160 decibels. A suppressor reduces the noise level to about 130 decibels. So you’ll hear a ‘bang,’ but it won’t be as loud as it would be without the suppressor.

Is it Legal to Construct a Suppressor?

Yes, certainly. It is completely lawful to construct your own suppressor if you have filed an application and got clearance from BATFE using ATF form 1.

But keep in mind that creating a suppressor requires the use of specific equipment and a thorough understanding of the art. You must also live in a state where suppressors are legal.

Are Suppressors and Silencers the Same Thing?

Yes, indeed. The Best Glock Silencers & Suppressors are both terms for a device that muffles the noise made by a firearm when it fires a bullet. The phrase suppressor is a more informal phrase used by the general population, while silencer is a more legal phrase used in documentation.

Do Gun Suppressors Degrade Over Time?

Yes, they do to some degree. Everything has a lifespan. The gasses leaving the barrel put a lot of strain on the suppressors.

Their function is to effectively manage this pressure, thus they, like the barrel, will wear and tear with time. However, how long they last is determined on their quality, upkeep, and shooting times.

Is a Silencer Effective in Slowing Down a Bullet?

No, that’s not true. A bullet is not slowed by a suppressor. It doesn’t get in the way of a bullet’s movement. They are, however, known to help with accuracy.

Is it possible to have a silencer on any gun?

The Best Glock Silencers & Suppressors may be attached to any pistol that has a threaded barrel and an appropriate adaptor. Silencers have been found on weapons ranging from subcompact pistols to large caliber rifles. The main thing to remember is that suppressors work best when they’re utilized with the right caliber.

Furthermore, suppressors for big caliber firearms will function on lower caliber firearms, but not the other way around.

Know-how: Operating principles of silencers for weapons

A silencer alone can basically only dampen the muzzle blast. The acoustic effect of the “pressure wave” is reduced by reducing the difference between the gas pressure of the propellant gases following the bullet before they enter the environment.

Best Glock Silencers & Suppressors

There are different ways to do this and we will explain in detail how the Best Glock Silencers & Suppressors works on a gun.

If you are not quite sure if you know the difference between the muzzle blast and the bullet blast, please click on the link provided with the two terms. Here you will find the most important details about it.

To reduce the noise of a shot, there are technically the following possibilities:

  1. the release of the gas pressure in an “intermediate storage”.
  2. the rapid cooling of the gas temperature
  3. turbulence of the gas flow and throttling of the gas flow velocity.

Let’s get into the details of each of the three possibilities:

  1. The relaxation of the gas pressure by more space:

It sounds almost too pragmatically simple, but expansion space as a buffer for the gases is the simplest way to lower the peak gas pressure in a shot. An initial, partial expansion still takes place in a space sealed off from the environment.

Well known from movies and stories is a simple PET bottle on the gun muzzle. Even this primitive solution alone represents a quite effective “silencer” and ensures a significantly reduced peak sound pressure level.

2. Cooling the gas temperature:

Cooling the gases removes energy from them and thus also provides a reduction in pressure. The inside of the Best Glock Silencers & Suppressors acts as a heat exchanger.

Best Glock Silencers & Suppressors

This is achieved, for example, by large surfaces (metal mesh and metal wool are also very suitable) or simply by liquids that can be vaporized or atomized by the hot gases.

  1. Turbulence of the gas flow and throttling of the gas flow velocity:

Gases flow. The orifices inside a Best Glock Silencer & Suppressor do not simply serve to separate the expansion chambers of a silencer, but are designed to “break up”, “redirect” and “work with” the gas flow.

The aim here is to lower or redirect velocity and flow direction. There are virtually no limits to the variety of orifice geometry. The spectrum ranges from the simple flat “washer” to the elaborately milled monolith.

In addition, there is also the theoretical possibility of frequency modulation of the shot bang:

Not every shot sounds the same. When using a silencer, the “hearing experience” is even more differentiated. For example, some models sound duller and thus significantly quieter than others, even though the peak sound pressure level indicates a comparable noise exposure.

This is due to the fact that people generally find low-frequency sounds more pleasant and therefore also subjectively perceive them as “quieter” than high-frequency sounds. This effect usually occurs with quite large-volume silencers.
