Pistol Suppressors: The Best Options in 2021

Pistol Suppressors: The Best Options in 2021

The Year 2020 may have set records  for sales of firearms, ammunition, and pistol suppressors. We think now is as good a time as any to take a look at the best pistol suppressors that are available for 2021.

These may be the most unusual years in our lifetimes due to COVID-19, social distancing, stay at home orders, quarantining, remote working, and the upcoming presidential election. In the early days of the crisis, we saw hoarding of ammunition and firearms like handguns with a seemingly unprecedented level of panic buying. Now it appears to be spreading to the NFA (National Firearms Act) realm, particularly with suppressors.

The rush to buy firearms, particularly among those first-time buyers who previously either sat on the fence, were outright opponents of the Right to Keep and Bear Arms or those who never got around to it completely overwhelmed the NICS (National Instant Check System). The system reported delays as long as three weeks for many unlucky citizens.

On the NFA side, wait times which can normally run from six months to a year are holding steady, if not speeding up a bit. This may be the time to get ahead of the curve if you have been considering the purchase of a pistol suppressor. If you’re in the market but not sure what to buy, we’ve done the research for you.

How to Choose a Pistol Suppressor

Pistol suppressors are looked down on by a lot of shooters because pistols do not come across as particularly loud when compared to the sound report of a full-sized rifle cartridge. Adding to that is the fact that while rifles are more than often carried by hand or by means of a sling, a pistol is typically transported in a holster. A suppressed pistol is usually not carried in this manner and the extended length with a suppressor attached makes a pistol harder to carry concealed.

However, a suppressed pistol can make for a valuable training aid as they reduce recoil and noise flinch. Additionally, they are some of the most fun shooting handguns out there.

There are many factors that go into choosing a pistol suppressor. Although they all look outwardly similar, each one has its advantages and drawbacks. The bottom line is that it all boils down to what each particular shooter is looking for. There is a difference between what a shooter who only shoots one caliber or has very few capable hosts needs and what someone who has a threaded barrel on every handgun they own.

For most shooters, weight and length are going to be important considerations; sometimes a can that is too long will impede the balance of the handgun. For a CQB type suppressor, length and durability are more critical. Someone who has an assortment of firearms that can share a pistol suppressor may have to evaluate whether it is easier to go with a fixed thread pattern or one that is capable of using various thread adapters.

Most pistol suppressors can easily be converted from one thread pitch to another by changing the booster or a piston. This is usually a by-product of a Nielsen device.

The Nielsen Device

The Nielsen Device was invented by the late Mickey Finn of Qual-A-Tec and was designed to push the weight of the suppressor from the barrel to aid in reliability. According to AAC (Advanced Armament Corporation), one of the first companies to commercially offer this type of system, the device works as follows:

“Upon firing, high-pressure gases enter the silencer and propel it forward against the tension of the (booster’s) spring. While the majority of the silencer’s weight is in this ‘floating’ condition, the host weapon’s firing cycle is able to proceed unhampered. The spring within the (booster) returns the silencer to its unfired state, ready for subsequent shots. This sequence of events takes place so rapidly, the shooter is unaware it has occurred.”

Previous Nielsen Devices were a modular component that had to be added to the suppressor or the host pistol and hampered sound reduction, making the suppressor noisier. By making the booster or piston an integral part of the system, manufacturers realized they could make interchangeable threaded mounting adapters instead of a dedicated rear cap. These threaded pistons meant that pistol suppressor could be used on more than one firearm with different thread patterns such as ½-28, ½-32, and Metric 13.5 x 1 LH.

If there is a drawback to the piston or booster system in handgun suppressors it is that it will not work well on a fixed barrel firearm such as a carbine or rifle. As the expanding gases move through a suppressor with a spring-loaded piston on a barrel that is stationary, a malfunction can occur which can damage either the firearm or the suppressor. The solution here is to use a properly sized fixed barrel spacer in a pistol suppressor when it is mounted on a pistol caliber carbine or rifle.

Pistol caliber carbines are not the only long guns that can benefit from the use of a pistol suppressor. Certain rifle cartridges like 300 Blackout and 350 Legend can be effectively suppressed with most pistol silencers. The benefit to this is that pistol caliber silencers are most often less expensive than their rifle caliber counterparts. If you are thinking of going this route, check the manufacturer’s ratings to see if the suppressor can withstand the round in question.

Wet vs. Dry Suppressors

Another consideration when looking for a pistol suppressor is whether or not the suppressor has the ability to be run “wet”. What this refers to is the use of an ablative within the suppressor to make it quieter. The most common ablative is a bottle cap full of water poured into the body of the suppressor from the rear prior to mounting. Some shooters use wire pulling gel, sonogram gel, oil, lithium grease, or another semi-permeable liquid.

The science behind this is that the medium cools the molecules of the hot expanding gases and imparts less sound, particularly the dreaded “first round pop”, when the projectiles exit the suppressor body. It works best in rimfire and pistol caliber suppressors but is not recommended for rifle silencers.

It is important to evaluate your needs and goals before you go into this and to even consider future needs and goals, as these do tend to change over time. You may have only one 9mm pistol for which you will need a suppressor at this time. That may change in six months or even 3 years from now should you add a .45 caliber handgun to your collection or maybe a short-barrel rifle or braced pistol that has a threaded barrel and shoots a pistol caliber.

Finding the Right Suppressor for You

As we mentioned earlier, the best pistol suppressor can mean a lot of different things based on the shooter’s needs. At first glance, most of these pistol suppressors look very much the same. However, each one is different enough that a closer look will bear out what shines about each model.

Always remember, it is your firearms that will dictate which one works best for you. If you own a lot of firearms besides just a G19 with a threaded barrel, you will want a pistol suppressor that can not only be readily used on your Glock but can handle different thread patterns in 9mm or can be used on your 45 or even a 10mm. In those cases, a simple 9mm suppressor will not be up to the task but the multi-caliber BANISH 45 would be perfect!

Aside from your specific needs, versatility with regard to mounting and calibers is important in the suppressed realm of shooting. If your collection is small and you are looking to expand it, try to factor in what you may want to add in the future. Remember that larger diameter pistol silencers in .45 can be used on firearms chambered in pistol calibers that are smaller in diameter such as 380, 9mm, 10mm, 357 Sig, 300 Blackout (subsonic) and even 22 rimfire, although we typically recommend a rimfire specific suppressor for the latter.
