Like other Erector model suppressors from Q, the Erector 9 is a modular, tubeless, 9mm suppressor that can be configured any way you would like to use it. Each module of the 9 is a baffle that connects to the other baffles. This means there is no outer tube so you can choose to assemble the Erector 9 with any number of baffles you want, from one to ten. The Erector 9 is made from a combination of stainless steel and aircraft-grade aluminum, keeping the weight down to just 8 ounces full assembled.
The sweetest part of the Erector 9 is the modularity of it. If space is an issue, you can make it as short as a single baffle, which will not be nearly as quiet as other suppressors, but you will see some benefit. You can also attach all ten baffles for a total length of just 8.8 inches and have a very quiet 9mm suppressor. The choice is yours, which is a very nice touch.
