Let’s begin the discussion with a fun fact.
Silencers and Suppressors refer to the exact same thing, however, silencer is the legal term, where suppressor is a casually used word for the same device. Silencers don’t actually silence the firearm, but they do reduce the shooting noise and recoil to some extent. A silencer is generally used so that the firearm creates less noise and flash during events like home defense, hunting, range shooting, or when used in noise restricted areas.
Since Glocks are among the most popularly used handguns for all such purposes, we will learn about the benefits of adding a suppressor to a Glock. We will also review the top-of-the-line suppressors available for Glock pistols on the market. As a wrap-up, we have prepared a small FAQ section as well.

How to Choose a Glock Silencer
Choosing the right silencer for your Glock requires you to consider certain aspects. These factors outline the important qualities of an ideal Glock suppressor and which you should look for when buying one.
The type of material used for making a silencer is directly related to its longevity. A silencer controls the pressure of expanding gasses, which is the cause of sound reduction. But a silencer made from less effective metals can melt down or crack, especially under repetitive auto fire, so it's better to choose a more durable and reliable silencer. Probably one made from some sort of hardened alloys.
Silencers are not interchangeable among different calibers. You can still use large caliber silencers on small caliber weapons, but that’s really not feasible and requires different mounting mechanisms. So always choose a suppressor matching the caliber of your Glock.
Suppressors can either be thread-pitched or quick detach. Take note of the thread pitch of your Glock’s muzzle so you buy a silencer with compatible threading. If you want to interchange your silencer among different weapons quickly, you can also go for a quick detach type silencer.
The prime purpose of a silencer is sound and recoil reduction. A 9mm pistol makes a sound of about 160 decibels. The safe limit of sound for your ears is 85 decibels. So adding a silencer to your Glock is an intelligent decision. Furthermore, you should purchase a silencer with significant levels of noise and recoil reduction and probably appealing aesthetics.
POI stands for Point of Impact. It is the shift in the aiming point of the weapon after you mount a suppressor to the barrel. Consider buying a suppressor with a minimal POI shift.

Are Gun Silencers Legal? - Regulation 101
Yes, in the majority of states. Silencers for guns are legal in 42 out of 50 states of the United States of America. However, that does not imply that you can just buy it on an online sale and expect it to reach you with a week. The sale and possession of silencers are explicitly regulated by the law.
Silencers can be compared to receivers, as they have their own serial number for registration purposes. To buy a silencer, you have to pay a tax of $200 through a revenue stamp. Not only that, buying a silencer requires you to go through a criminal background check. The possession of silencers falls under the authority of the National Firearms Act (NFA) division of the BATFE (Bureau of Alcohol, Tobacco, Firearms, and Explosives).
The illegal possession of silencers is considered to be a serious crime and can buy a violator a term of up to 30 years in prison. Some states and municipalities also have their local laws regarding the use of silencers. For example, Connecticut and Vermont allow the possession silencers but prohibit hunting with them.
How to Attach a Glock Suppressor
Note: Please check your Glock for safety before attempting any kind of service or maintenance. Remove the magazine and pull the slide to cross verify.
Attaching a suppressor to a Glock is not that complicated, especially if you know how to disassemble and clean it. But before we start, you must take note of the fact that you need a muzzle threaded barrel for mounting a suppressor. Factory Glock barrels don’t have that, so you might have to get a new one.
Now, cock the action back and push the takedown leverage pin to remove the slide. Once it is done, remove the recoil spring gently from the slide and set it aside. Now, pull the barrel out, and replace it if it's not threaded. Put the barrel into the slide, drop the recoil spring back into position, and lock the slide on the receiver using the takedown pin.
Next, take the silencer and screw it all the way down on the threaded end of the barrel. Make sure to tighten it properly, but not too tight. Now, cock the slide all the way back and pull the Glock trigger to check the mechanism. Aim the Glock in a safe direction to check the POI and if the sights are aligning properly.
For more detailed instructions and the steps involved, please take a look at this video below:
The primary purpose of installing a suppressor to a Glock is to reduce the noise created upon firing a shot. Suppressors are known to reduce this noise by almost 20%, which is a good feature for general use and tactical situations. A good suppressor must be durable, reliable, easy to install, easy to clean, and should not interfere with the POI.
People Also Ask
Your brain might be buzzing with some questions you need the answers for right away. To address the general doubts related to this topic, we compiled a short FAQ section to help you, so you may still your thirst of curiosity.
Do I Need a Threaded Barrel for a Silencer?
Absolutely, yes. A threaded barrel is required to screw on the threads of the silencer since it is a more sturdy and reliable setup because the bullet exits from the muzzle end. However, there are suppressors with QD mounts that can be screwed onto a threaded barrel for quick attachment and detachment.
How Does a Silencer Work?
To understand that, you must understand what creates the noise. When you shoot a bullet, the heated gasses created by the burning of gunpowder expand rapidly, thus propelling the bullet out of the barrel. When these gasses exit the barrel, they transition from extremely high pressure to low pressure, which creates the sound. A barrel provides extra space to make this transition more gradual and efficient, which results in a reduction of noise.
Do Gun Silencers Really Work?
Yes, they do. But not in the way Hollywood shows them to work. You’re not going to hear a ‘whip’ sound when you fire your weapon with the suppressor on. For example, shooting a 9mm Glock creates a sound of around 160 dB. A suppressor brings it down to approximately 130 dB. So you’ll definitely hear a ‘bang’, just not as loud as without a suppressor.
Can You Legally Make a Suppressor?
Yes. It is perfectly legal to make a suppressor on your own if you have submitted an application and received an approval using ATF form 1 to BATFE. But remember that making a suppressor requires specialized tools and appropriate knowledge of the trade. Plus, you have to reside in a ‘suppressor-legal’ state.
Are Silencers and Suppressors the Same Thing?
Yes. Silencer and suppressor refer to the same thing-a device that is used to dampen the noise created by a weapon when it shoots a bullet. Silencer is the more legal term used in paperwork, whereas suppressor is a casual term used by the general public.
Do Gun Suppressors Wear Out?
Yes, to some extent, they do. Everything has an age. The suppressors undergo extreme pressure of the gasses exiting the barrel. Their job is to handle this pressure efficiently, so they will undergo wear and tear over time, just like the barrel. However, the longevity depends upon their quality, maintenance, and shooting durations
Does a Silencer Slow Down a Bullet?
No. The silencer does not slow down a bullet. It does not interfere with the movement of a bullet. However, they are known to often aid accuracy.
Can Any Gun Have a Silencer?
As long as a gun has a threaded barrel and an apt adapter, it can have a silencer. Weapons ranging from sub-compact pistols to large caliber rifles have been known to have silencers. Although, the important thing to note here is that suppressors perform the best when used with their respective caliber. Plus, large caliber suppressors will work on smaller caliber guns, but the reverse is not possible.
