GSL’s 9mm Stealth Suppressor: Versatile Tool for Quiet Recreation

GSL’s 9mm Stealth suppressors are the most adaptable platform on the market. If you are going to pay a $200 Tax, you want to use this can in every 9mm application. Stealth’s modular design has interchangeable adapters for, well, everything. You can select a piston core for handguns or one of five adapters for your favorite mounting system. This will support any 9mm rifle, pistol caliber carbine, sub gun or pistol.

There are many reasons people own and use silencers (as the BATFE calls them). They can make your guns hearing safe and make your shooting discreet so your neighbors don’t complain. This is also a great training tool for new shooters.

Buying suppressors is a complicated process with wait times and paperwork. Choosing the right suppressor requires some education and research. Most buyers can’t test fire one, even if the store has a range, your dealer may not even have the model you want in stock. Many times you have to pay in advance. The BATFE paperwork can be reversed to return a suppressor, but that is a poor option. There is no replacement for product research.

The Stealth has a traditional baffle design. Baffles are barriers inside the suppressor which disrupt, redirect and slow the gas coming out of the barrel. The gas which exits the suppressor is slower and cooler with less blast and noise. This makes shooting more pleasant for the shooter and everyone else around them.

There are a number of factors you need to consider. Quality and value are the most important. GSL promises a silencer as good as or better than anything on the market at a lower cost. With the modular design, you can ensure that you will be able to suppress future guns you don’t even own yet.

I highly value the ability to use the same can for many applications. As a writer, I get a lot of different guns and I can’t buy a new can for every test. The Stealth is so versatile, it is the only 9mm can you will need for any 9mm application.

The noise reduction of 34db is substantial. The perceived noise is hard to describe effectively but has a low tone which reduces the sharp snap of the report. It is well balanced and light. With sub-sonic ammunition, it sounds like .22 short.

The perfect handgun host for the Stealth 9mm Suppressor is the P320 RX Full-Size. This modular striker-fired pistol comes with SIGLITE Night Sights suppressor height sights and a slide-mounted ROMEO1 reflex optic installed and zeroed.

The P320 offers a great trigger, an intuitive, 3-point takedown, and unmatched modularity. The full-size frame is the ideal host for a suppressor. This modular, striker-fired pistol features a full-size grip and full-length slide.

The ROMEO1 is high enough to see over the Stealth and provides faster target acquisition and improved accuracy.  A 3 MOA Red-Dot with multiple intensity settings provides rapid target engagement under any light conditions. Extremely strong and lightweight aircraft grade CNC Magnesium is tough enough to handle daily carry.

The Stealth moves quickly between roles. The adapters are simple and quick to change. In this photo, the handgun piston core is attached to the barrel and the suppressor body is separated.

I used SIG Sauer’s line of M17 9mm +P ammunition for my initial testing. M17 ammo is currently available loaded with ballistically matched FMJ or V-Crown JHP projectiles. Both of the 124-grain projectiles ran well in the 320 and the QC5.

 

The suppressor body can be easily attached to any of the adapters. This Quarter Circle 10 QC5 9mm pistol has a 3 lug HK mount. Using the adapter, the suppressor is quick to attach and quick to release, even when it is hot.

Here is the suppressor body separated from the adapter mounted on the QC5.

The QC5 is another great host for a suppressor. The MP5 magazines feed reliability and provide a nice mass to balance between the magazine well and foregrip.  The Stealth screws on and off easily yet cannot shoot loose, even in rapid fire. I did not see any zero shift with the Stealth installed. It proved reliable with a variety of ammunition.

I have fired several thousand rounds through the Stealth in a variety of handguns, carbines, and rifles. The shift in impact is minimal and the reliability has been perfect so far. All I have done to clean it so far is wiping the threads on the connectors.

The Stealth can fill any role and provides the ultimate in 9mm flexibility for a single tax stamp. Each silencer is an NFA device and must be registered with BATFE with a $200 tax stamp. If you are interested in silencers, find out if they are legal in your state and then locate a dealer. There is paperwork, but it has never been easier to buy one.

Many law enforcement agencies have added OSHA approved sound reduction devices to their carbines. They are tired of paying out disability claims for hearing loss. You can shoot with the same level of comfort and safety.

The Stealth is the first GSL suppressor I owned, but it will not be the last. Value is a combination of quality, performance, and price. The Stealth does not disappoint. If you are seeking a 9mm can, you need look no farther.

Greg received his first suppressor design patent in the early 1990s for the Helical Suppressor and was featured on the cover of Machine Gun News. Shortly thereafter he was hired by Gemtech and became president a couple of years later remaining in that role for 22 years, and was also the lead designer and engineer. GSL built all of Gemtech’s silencers from 1995 to 2005, and most of them until recently. After Gemtech was purchased by Smith & Wesson, Greg separated and began building cans in his Michigan facility.
