Modular, super lightweight.. Minimal POI shift on glock 17.
Timothy B –
Perfect in every way.
Braeden M –
For a pistol suppressor it is perfect. Having the ability to change the length quickly and easily is great. For an SMG however I would recommend a one or two piece suppressor.

I tried multiple 9mm cans with buffer/piston/Nielson devices and none of them worked on my 9mm handguns, constant stove pipes, jams, not cycling, etc. But this Q Erector 9 works perfectly. I even tried the JK 105CCX that is supposed to work without a piston/spring unit, and even the JK 105CCX didn’t work. But this Q Erector 9 works flawlessly.

Incredibly light weight. Zero issues on a Glock 19x MOS and FN 509c Tac. Very easy to remove sections. Works great with 3 sections removed. Gets rid of the blowback, but still keeps the sound levels down. Full length configuration is very quiet.
Jeff F –
It’s shocking how light this can really is. You hardly feel it is attached to the gun. It’s also very quiet. Firing subsonic at steel is a lot of fun with this. I have only used it full length and for now don’t have any desire to shorten it. Accuracy is no problem with this as well. The only issue is it gets extremely hot with use. I’d recommend this can with no hesitation.
Joshua Vazquez –
This suppresor is extremely nice and very very light. The only reason why I didn’t give 5 stars is because the paint finish isn’t the same color on each removable baffle. Some were darker and lighter then others and kinds killed the initial look of it. I don’t really care to much about the finish issue and everything else on this suppresor is top shelf.
Justin M –
First shots out of the box really blew my mind. I did use heavy subsonic ammo in my p365xl but was not expecting this type of nose reduction. It sounded like a .22. I haven’t experimented with taking baffles out to see how small I can get while keeping the gun “quiet” yet, but betting I can probably go halfway. The gun did have some issue with cycling. The next round would load, but the striker wasn’t cocked some of the time. I think that’s also to do with the heavy ammo on such a small gun. Normal 115 grain ammo probably wouldn’t have caused an issue. Can’t wait to use it some more and fine tune the set up for home defense!

Looks great on my Stacatto and super light which is what I was needing.
Victor Miller –
Nice and quiet
Bryan Raffaniello –
It’s super light, even at full length. My steel Frame Berettas, Sig’s, always had a Hard time Cycling, this is definitely fit for any Small, Midsized, to Full Frame light as a feather Silencer. Only part that is way more Obvious than I Thought, is the brass ring. It’s a dead give away. & more Sand than Coyote as FDE Goes. Other than that. No Cycling issues yet, made Just for a 9mm. Which is a Plus for decibel reduction. Great Buy, No Ragrets, Lol.

I can’t believe how light weight this unit is. I put it on an Sig P365 and fired two rounds into a dirt pile right outside my house and it’s unbelievably quiet. I like that you can remove a few baffles depending on your decibel/size requirements as well. Absolutely recommend this suppressor to anyone.
Justin H –
Works great, put about 50 rounds through it right when I got it out of the box.
Alexandre P –
Great product
ELBERT –
Very quiet and very modular. Highly recommended.
Erik H –
It’s light, modular, it’s quiet it’s clear anodized and it’s Q. 10/10
Michael E. Kerr –
Great deal on this lightweight can. Bought it with the tax stamp deal. A real bargain.
Michael C –
Ordered this in Desert Sand and they sent it in a darker FDE instead. They said I could send it to Q and get it refinished. What a joke It’s not my fault their employee pulled the wrong silencer They should double check before starting the approval process with the ATF

My Erector 9 is an incredible suppressor—lightweight, modular, and highly versatile. The ability to adjust its length is a standout feature. Naturally, the shorter you configure it, the louder it gets, but this flexibility allows you to tailor the suppressor to different applications.
I was particularly impressed when shooting 147-grain 9mm ammo with only two baffles out of a Staccato P—it remained hearing safe, which exceeded my expectations.
The suppressor comes pre-equipped with a Nielson device, but I also purchased a 3-lug adapter and a direct-mount adapter to expand its compatibility across multiple firearms. Both adapters are exceptionally well-made and highly functional.
Overall, I highly recommend the Erector 9 for anyone looking for a lightweight, modular, and adaptable suppressor.
Mark Lopez –
Nice suppressor. Quiet. Probably won’t use the modular aspect of it. The tools for dissembling are nice (even if proprietary) but would have been nice if they had handles. Mine is difficult to take apart by had (with the tools). I had to get a couple of 2″ wide jaw wrenches that make it easy without putting one in a vice (that you still need a tool to turn the other one).

Quality and Quiet
