is selling a transferable Mac-11 in .380 acp and it comes with a working briefcase. We all know of the H&K briefcase for the MP5K well there is one for the MAC-11. It is not quite the same as the H&K briefcase though. The H&K briefcase uses a modified claw mount to hold onto the MP5K receiver whereas the Mac-11 is held in with a custom molded interior and velcro straps. The H&K Briefcase has a metal shroud that protects the inside of the case,

The MAC-11 case does not have the metal shroud but it is suppressor compatible.


One major difference is ow the guns are fired while inside the briefcase. The H&K briefcase has a trigger built into a fixed handle with an integrated safety. The MAC-11 briefcase has a large pivoting bar and is actuated underneath the brief case. Which requires the shooter to use two hands. In the video above you saw the shooter cradled the briefcase under his arm to shoot it. This is a bit more stable than shooting the H&K Briefcase one handed. Although most people with H&K Briefcases tend to shoot them sideways and braced against their stomach. Also their support hand can hold onto the bottom of the case and control the briefcase while firing.

I am not sure what the hole is for next to the actuator bar. One aspect I like about the H&K Briefcase is that it has a trigger safety on the handle. There does not seem to be safety for the MAC-11 Briefcase.


In case you are interested, NFASales is selling this MAC-11 and briefcase for $7575.

    MAC M-11. No such thing as a MAC-11. Nor MAC-10.

    • FearlessFarris

      I know certain 90s era rapper who would beg to differ.

      • DangerousClown

        Eric Wright lived not too far from me when he died. Funny that he chose to live in the whitest of white neighborhoods. I think he would approve of this briefcase, for when the fools kept steppin’.

    • iksnilol

      There is.

      Just like AK can refer to a whole host of different firearms even if it ain’t their official tizzle name so can MAC-10 and MAC-11 refer to the two specific guns.

      • autofull– kevin horning

        i remember selling one or two of these in the 70,s. i do not remember when, but the atf decided to classify them as an aow device. the slot on the projectile opening is set up to put your calling card in the slot to hide the opening. thass what i recall, kevin.

        • iksnilol

          The 70’s were truly a wild time.

          Did you do cocaine and bellbottoms?

          • Peyton Quinn

            You are mixing up two different eras my friend 1965 Bell bottoms) and the later 70’s (cocaine cowboys).

          • iksnilol

            it’s all just a blur… mainly due to the LSD.

            At least that’s what I thought about y’all. But from what I know about fashion, bellbottoms were a staple of the 70’s as well.

          • Brett baker

            Wasn’t Little Feat’s “Sailing Shoes” from the early 70’s?

          • Samuel Millwright

            If you do enough cocaine you end up in a leopard print “Japanese slingshot” anyway…

            80’s movies were awesome … Dolly parton burt Reynolds texas… I’m pretty sure there was a transam in there somewhere too …who am i kidding… Of course there was a transam

        • ShooterPatBob

          None of what you recall is accurate.

    • Peyton Quinn

      Not so I had one a Mac 11 in .380, government issue no spy case though just a sionics suppressor and one 20 and one 30 rd mag.

    • Zapped 02

      If you really want to get picky it’s actually the Ingram model 10 and model 11 made by military armament corporation.

    • jcitizen

      We called them the short version just because, back in the late ’70s. The SM-11-9 was my favorite.

  • Badwolf

    Seems fitting that mac11 comes in a less sophisticated case than mp5k. But as long as it works…

  • Brett baker

    We all need one of these.

    • Stuki Moi

      Does anyone here know of an instance, where these things were used for a practical purpose?

      They do put the MAN back in manpurse, though…….

      • Brett baker

        I think I saw them used in several documentary films about the Cold War made in the 70’s and 80’s.

  • Stuki Moi

    With the trigger under the case, is it dropsafe?

    • Some Rabbit

      Hit it with a hammer to find out.

  • shooter2009

    When I took my MP5 operator course with former SAS Phil Singleton (who was part of Operation Nimrod), we all got to shoot the briefcase as part of the course.

    Same with the MP5 instructor course.

    But, it’s not traditionally fired from the “briefcase carry” position. The correct method was to flip the briefcase horizontally, brace it against your groin, and *then* activate the trigger mechanism.

    I can hear you all snickering…but, yes, it was a rush.

    • Tassiebush

      That is very interesting. I remember a fellow who’d served with an F1 submachinegun saying how they were taught to centre the butt on their belly to point shoot. If anything the square shape of the case sounds like it would be very clear in where it was pointed.

    • JJ

      Hey, no fair. I didn’t go through his mp5 course, but I didn’t get to try out anything like that when I went through the HK MP5 operators certification. Although a great time, I feel like I just got the hamburger meal deal now. Where was the cheese? Must have been fun. The MP5 is so controllable at the trigger and in recoil.

  • Mike

    I want two. Firing both at once.

    • DangerousClown

      Plus the rocket launcher guitar case?

      • Tassiebush

        Or there’s this…

      • ozzallos .

        I’ll pass and just take Salma Hayek, thanks. And her giant albino Boa.

  • codfilet

    Big Mac attack?

    • Peyton Quinn

      Now that I think on it, it was maybe not a MAC (exact same design) but I seem to remember it reading “Powder Springs” on the receiver.The weapon was made by a few manufactures besies Military Armaments Corporation (MAC)

      • JJ

        Cobray, Mac, Ingram, SWD were some of the makers. Made in Tn, Stephensville, Tx, Powder Springs. Masterpiece Arms is the newest maker. They changed a few things internally and use Stein mags. I have a MPA930 mini Mac. Smaller than M11 380 by a good measure. Works flawlessly and sights are accurate to 25yds which is remarkable. Fun gun for what it’s is but a Glock with 33rd mag is much easier to deal with.

        • Peyton Quinn

          The sten magazine (a single stack design) was the main failure of the STEN. The Stering corrected this with double stack ma with roller top loading (demanding no loading tool like the STEN did also. IT was a very reliable SMG. Any weapon using STEN mags is going to be prone to jams I feel. My powder springs model was flawless in operation too using non sten mags. I could hit in the kill zone at 25 yards with it but not consistently, and without the suppressor to hold onto it was “spray and pray”

      • Rollin L

        I believe the original Military Armaments Corp manufacture was in Powder Springs, GA. So you may well have had the real deal, original production.

  • Squirrel

    I seem to recall reading in Robert Baer’s book a story about one of the few documented incidents involving one of these briefcase guns. Apparently a CIA officer in South America put one of these up on the bar of his local watering hole and it ND’d and “nearly cut the bartender in half”

  • Aaron Wagner

    A trigger at the bottom and no safety? What could go wrong?

  • Some Rabbit

    Spies and their toys, smh.

  • Peyton Quinn

    I took this same weapon when working at the embassy because it was small,light and concealable. (no briefcase) It had a sionics suppressor, without which it’s 1200 rpm was all but totally uncontrollable. Not easy to hit anything with it except at 5 or 7 meters! Sounded like an air wrench more than a full auto weapon.This is the first time I have since then heard anyone even know the .380 (9mm Kurtz) was ever made in Mac 11.I will say I never had it jam on me and I practised a lot since the ammo was provided by Uncle Sam. This is a are gun in my view and with the briefcase even more so.

    • JJ

      Several companies made closed bolt versions of the mac-11 in 380. There was also the mac-12 380 closed bolt made by at least 1 manufacturer. Maybe 2. Masterpiece Arms makes the mini mac 9 which I think is smaller than either of the others. Closed bolt also.

      • jcitizen

        My favorite was the SM-11-9, which was really an elongated .380 version in 9mm. It was the best damn subgun I ever shot. I could bump the trigger and make the ammo last quite a while, and hit targets with ease, with no sights. Of course the suppressor made that possible. I never tried sub-sonic ammo, but I assume you would need a special spring or bolt or both to shoot those. It was still plenty quiet, even with regular ammo.

  • codfilet

    This would be very useful if you were a double-naught spy…….

  • USMC03Vet

    Open bolt, no safety, levar on bottom.


  • MegaGlide

    You pull the lever to the rear to disengage the safety. Had one in the ’80s.

  • CountryBoy

    IMO the difference in quality behind the design and execution of these cases is astounding. The HK seems like it would stand up to abuse, such as running and banging the case around, without the gun becoming dislodged. The Mac, not so much; relying on sprayed-in, molded foam (which is what it uses, and it can be deformed/crushed), doesn’t ensure that the gun stays put within the case. Having the gun shift will definitely add excitement when used, or perhaps when an AD occurs. Remember, there is no safety on it, and if the gun shifts in a “good” way the gun might not fire when needed either.

  • DistalRadius

    The lever on the bottom actuates both trigger and safety. Pulling the lever rearward pushes the safety forward, disengaging it. Pushing the lever forward pulls the trigger rearward, firing the gun. A business card is placed in the holder covering the muzzle hole. This case is intended for use with a suppressor which is not present.
