GSG MP-40 in 9mm?

Stopping into the German Sport Guns (GSG) booth found me eye goggling a very nice piece of WWII history, the MP-40. This was not the version currently offered by GSG in .22LR, and imported to the United States by American Tactical Imports; no, this one was chambered in the original 9x19mm. As a huge WWII history buff, I was immediately interested in the potential of having a semi-auto version of a weapon that infamously made history.

My intent staring (drooling) must have attracted floor representative, Andreas Speichinger. I’m not sure if he was thrilled at my interest or worried about a grab-and-go! Despite the language barrier I was able to learn that the GSG MP-40 in 9mm is just a prototype, but GSG was going to gauge the feedback from SHOT Show attendees to determine if this version would be popular enough to mass produce.

Say what?! Of course a 9mm version of the MP-40 would be popular. There was no language barrier in my exclamation. Being only Tuesday, Andreas told me that so far responses had been overwhelmingly positive, so the GSG MP-40 in 9mm may become a reality by 2016. The dimensions are very similar but not exact to the original MP-40. Though labelled “Schmeisser” by GSG, I believe the original MP-40 was designed by Heinrich Vollmer (Hugo Schmeisser designed the predecessor MP-18, but did not design the MP-40).

Interestingly, Andreas attempted to describe GSG’s new locking and rotating bolt design for the MP-40 9mm that deviates from the original inertia straight blow back design. I’m sorry I can’t elaborate any further because the language break down hit a wall at the more technical components of the design. It is safe to say that the GSG MP-40 9mm action will not be the original design, and it was unclear why they would deviate on such an important function. Perhaps there are some German patents in the way.

Before you get you wet your chops too soon, Andreas emphasized that the 9mm version  has not gone anywhere beyond prototype level. There has been no major retooling for a mass run, no submission to BATFE for import approval, and no limited runs for special buyers. In fact, with a barrel of only 9.96 inches, GSG will likely have to jump through some hoops to make a general public viable version.

Here are the GSG 9mm statistics for now:

  • Length – 23.82 inches (605mm) without stock
  • Length with stock – Approximately 31.5 inches (800mm) – prototype did not have one
  • Barrel Length – 9.96 inches (253mm)
  • Weight (unloaded) – Approximately 8.26 pounds (3.75 Kg) – Andreas wasn’t positive
  • Capacity – shown with a 32-round straight magazine.
  • MSRP – Unknown (I’m guessing in the $1000 neighborhood)
  • Delivery Date – 2016 if we’re lucky!
Even without the collapsible stock, the GSG MP-40 9mm was great to hold.

Though the .22LR version had the original collapsible stock, but it also comes with an integrated fake suppressor to meet BATFE 16-inch barrel length restrictions. I guess they could call it a really long and heavy pistol! Andreas also said that GSG would likely make a 10-round magazine if the MP-40 9mm becomes a reality. It’s unknown at this time what GSG might do to make the MP-40 in 9mm acceptable to the gun nazis (pun intended)!

    All the yes.

    “I was able to learn that the GSG MP-40 in 9mm is just a prototype, but GSG was going to gauge the feedback from SHOT Show attendees to determine if this version would be popular enough to mass produce”

    are they kidding with this demand thing?

    • Aaron E

      I agree anon!

    “In fact, with a barrel of only 9.96 inches, GSG will likely have to jump through some hoops to make a general public viable version.”

    What does that have to do with anything its clearly in a pistol set up. Krink pistol have pretty close dimensions and are widely available.

    • scw

      People outside US are always baffled with the concept of those so-call “pistol”.

      • UCSPanther

        I call them “stockless carbines” myself…

      • Giolli Joker

        Aside people in the UK… their definition of legally purchasable “pistol” is beyond weird.

      • Yellow Devil

        Yeah well, it’s not just people outside the US that are baffled with the concept.

    • Aaron E

      BATFE be-grudingly allowed AR-15 “pistols” but they are much shorter. The magazine on the MP-40 sits well forward of an AR-15 pistol, making the weight distribution much more difficult to bear.

      I don’t care how they do it, just as long as GSG does do it!

      • Patrick Mingle

        They might rule that the mag well was designed as a vert grip making it an AOW

        • Aaron E

          True, hadn’t thought about that!

        • Juice

          I was thinking of that as well.

          When I first saw it I thought that this gun would be the ideal “pistol”, since it doesn’t have a stock but the gun would still be comfortable to hold. Now I’m slightly pessimistic.

          Let’s hope it will become fully-legal the way it is, without a stock. It’s not like holding a 9mm AR Pistol by the magazine makes it a foregrip right?

          • sianmink

            According to the latest ATF opinion, how you use something counts as redesigning it.

        • sean

          I.O. Inc. PPS-43C already legal

        • Vitsaus

          The weapon was NOT designed to use the magwell as a front grip. The soldier was meant to hold it by the finned portion behind the magazine, in front of the trigger. Hollywood has popularized the concept of gripping it that way, but Wehrmacht troops were trained to grip it like a rifle. Gripping it by the magwell could cause jams and other feeding problems much like the Sten guns.

  • mosinman

    this is even better than the .22 version next they need their STG in 8mm kurtz

  • FrenchKiss

    Great, another gun that can’t be had in kommiefornia.

    • Dan

      You are welcome to keep it at my house if you’d like. I live in South Dakota so I hope that isn’t too inconvenient for you.

    • The Brigadier

      So move. Between the Progressives and the Cartels what is keeping you there?

  • I’m honestly surprised this hasn’t been done yet. Valkyrie Arms makes a Grease Gun…

  • Vhyrus

    I’m confused…. Where does the Sig brace go?

    • nutria

      On your shoulder

  • noguncontrol

    huh? locking rotating bolt? this will use a gas system? crazy!! or maybe its a rotating barrel short recoil system like the beretta px4 storm pistol?!?!! they should stick to blowback, cheaper for a 9mm, like what the czechs did with the scorpion evo 3.

    • Aaron E

      I apologize that I couldn’t be clearer but trying to decipher what Andreas kept trying to say (no fault of his own) about made my head explode.

      • Matthew Groom

        You should carry a voice recorder and then you can get a second opinion as to what was said/meant later. Google Translate can give you a good idea what was meant if he uses any foreign words, etc.

        • Giolli Joker

          These German companies should send an English speaking rep or at least translator if no one among them speaks English.
          I remember about the same issue with Korth last year.
          It seems really counterproductive from their side.

          • morokko

            If the gun companies are anything like ordinary companies, they have no need for that when they send Very Important People. I mean, Las Vegas? Why would they send some simple peasant, even if he actually could speak english. Peasant should sit on dung heap in the cellar and translate marketing brochures. Business trips to exotic places are so important that have to be undertaken only by serious senior management these days.

          • Giolli Joker

            I get your point… however the guy mentioned in the article is not one of the 3 top managers of the Company, according to the “About Us” page on GSG website.

    • Chase Buchanan

      Perhaps it’s to make it that much harder to convert to full-auto, although I don’t know why they would need to go that far.

  • coucuroucu

    Hope this one wont be made of pot metal and plastic. The hi point level of materials would be a blasphemy in this case.

    • sianmink

      Sheet steel and bakelite or GTFO

  • Matthew Groom

    This would be so awesome. I’d want to get an SBR version, but I’d be happy if it made it stateside at all.

  • Blake


    mkay, mkay…

    Probably the best next step would be to submit the prototype to the BATFE ASAP so that they can get an opinion on it before committing more resources to production.

    I’d be all over a version with a 16″ bbl & folding stock too. Not a fan of paperwork & waiting.

  • gunslinger

    so.. when’s the arm brace gonna come out for this?

  • Nagurski

    Now they need to get working on a StG-44 in 7.62×39.

  • LRB

    SHUT THE FRONT DOOR! I’d buy 2, one to keep original, and 1 to SBR. HELL YEA build it!

  • Ratcraft

    Maybe I want one and maybe I DO.

  • sianmink

    “with a barrel of only 9.96 inches, GSG will likely have to jump through some hoops to make a general public viable version.”
    I think they could just import it as a pistol, right? Except ugh, our pistol import rules are so stupid.
    how about a version that will take Glock mags? XD

  • Vitsaus

    If only it wasn’t being made by GSG.

  • Kronk

    They have yet to deliver on promises of the .22lr pistol version, so as far as I’m concerned, this is already vaporware.

  • mmouse5000

    I would buy it! That is awesome. I just hope they put in reasonable quality…

  • Doom

    They could bypass all the Import bullshit if they brought it in as a “Pistol” either without a folding stock at all (ew) or with the folding stock attached but spot welded in a couple of places so that it could be easily SBR’d after you did all the stupid unconstitutional paperwork.

    Id suggest the spot welded stock on a “pistol”. They could even ship with the 32 round magazines that way too.

    If they could bring these in with stocks and they sold at around 800 street price I bet they would sell like hot cakes to people wanting to SBR them for a grand total of around 1k. I hope they are all metal/bakelite like the originals, or at least the plastic would act like bakelite. this would go nicely with my K98k for sure. Also Lose that retarded “Schmeisser” label, doesnt make any sense at all.

  • The Brigadier

    The Schmeisser was an incredibly fast firing submachine gun. If this can be made into a submachine gun then it will be a winner. As a semi-automatic, in spite of its clean lines, it will not be that attractive to most buyers.
