I’m a big fan of PCCs and subguns. I think it’s because I came of age during the time when the MP5 ruled and subguns were the dominant weapon for special forces, SWAT teams, and general bad hombres.

With that in mind, the GSG-9 that’s being imported from ATI caught my attention. GSG famously made clones of the MP5 in .22LR, but HK sued them, and the guns had to change in outward appearance. The latest in the GSG family of totally not MP5 look-alikes is the GSG-9.

GSG 9 – Not the German Counter Terrorism Unit

This is a 9mm large format pistol that’s an uncanny valley version of the MP5. It’s a direct blowback gun with some vague MP5 similarities.

The charging handle, safety, and general receiver design have a certain MP5 appeal. You can do the ol’ HK slap if you need to. Across the top is a long optic rail, and the handguard is all M-LOK. The GSG-9 lacks the HK drum sight, and instead, you have a simple peep and front post.

The pistol takes either GLOCK or SIG P320 magazines, and it does so in an interesting way. Instead of a modular magwell, the gun uses an adapter that fits onto the magazine itself. The GSG-9 can take either mag, and you get both adapters with the gun. ATI will also sell additional adapters for your magazines.

I’m not exactly sure how I feel about that design. It’s novel, but will removing and attaching adapters to your mags become a pain? What happens if an adapter breaks?

That remains to be seen. The rear of the gun has a 1913 rail for stocks or braces, and the overall layout is very simple and mostly polymer. It’s a simple little weapon, but it looks like it could be a lot of fun.

The GSG-9 will retail for around $699 and be available by the summer of 2023.

  1. …would rather put an adapter in the magwell than put one on each of my mags. :-/

    Any word on why they did it that way?

  2. “GSG famously made clones of the MP5 in .22LR, but HK sued them..”

    yes, its a fun gun. love it. too bad HK sued them though but I understand.

  3. I’d buy (assuming they are reliable) although an original MP5 would be preferred, but California–for now at least–will not let me. Didn’t H&K make an integrally suppressed MP5? that would be the cat’s meow!

  4. My main reason to get an MP5 style gun would be that it’s an MP5, or at least gets as close as possible to one, with parts commonality, classic looks, roller lock action. For a while MP5 options were either chopped up guns rebuilt or some questionable clones, but now there are lots of good options from HK itself, century MKE, POF, zenith, PTR, various builders, etc.

    If I couldn’t get one of the above models, I would rather get an airsoft, BB, or .22 version to scratch the MP5 itch than this GSG-9. There are lots of 9mm sub guns and PCCs so if it’s not going to really be an MP5 type gun, I could just get a Stribog, Scorp, Ruger, AR9, etc.

    For a while you could get some Frankenstein MP5 blowback thing from CDNN, but it was just kinda wacky. This reminds me of that.

  5. What’s up with the “it sure looks like a top-mounted grenade launcher” monstrosity on top of the barrel shroud (which appears to run the entire length of the gun)?

    I did not think it was possible for someone to manufacture a larger, more clunkier gun than Hi-Point: it sure looks like this thing puts Hi-Point to shame in the unnecessarily clunky category.

  6. امروزه با گسترش فناوری اطلاعات و ارتباطات، جرایم رایانه ای نیز به یکی از معضلات جدی جوامع تبدیل شده است. این جرایم می‌توانند در اشکال مختلفی مانند کلاهبرداری، سرقت اطلاعات، انتشار محتوای مجرمانه و… رخ دهند و خسارات مالی و معنوی فراوانی را به افراد و سازمان‌ها وارد کنند.
