Arsenal Firearms 2011-A1 Double Barrel 1911 in Slow Motion

Andrew at the GY6 Channel has blogged a teaser of his upcoming review of the Arsenal Firearms 2011-A1 Double Barrel 1911 pistol. The teaser features some pretty nifty slow motion footage.

Someone commented on the video “so this is like shooting a .90 caliber pistol?”. Unfortunately thats not the case. It fires single rounds from alternating barrels. Shooting more than one round per trigger pull would have it classified as a machine gun and unavailable for sale to consumers.

    So.. you posted a video without even watching it?

    “Unfortunately thats not the case. It fires single rounds from alternating barrels. Shooting more than one round per trigger pull would have it classified as a machine gun”

    Next time, if you’re going to report on something, maybe you should watch the video accompanying it first?

    The Arsenal double-barrel 1911 fires two bullets at once, ejects two cases at once, all with one single pull of the trigger. It is NOT considered a machinegun because it DOES NOT meet the definition of a machinegun. It is two firearms in one frame, essentially. There are two actions and two barrels. If it had one action and one barrel and fired two shots, THEN it would be a machinegun.

      That’s not what the NFA says.
      This is one firearm, it has one serial number.
      The NFA defines a machine gun as a firearm that fires more than one shot per trigger pull. That’s what the LAW says.
      Having said that, it’s the BATFE that interprets the law as to whether or not a firearm meets that definition..
      If they want to say it’s legal, well…

      • Christian Hedegaard-Schou

        Abbreviated machinegun definition from USC Title 26: “any weapon which shoots, automatically more than one shot, without manual reloading, by a single function of the trigger”

        The law does not mention anything about a single trigger pull, rather a trigger “function”.

        The trigger in the Arsenal 1911 enables two functions. One pull, two functions = not a machinegun.

        • Bill Funk

          That’s trying to have it both ways. It either fires more than one shot per trigger pull (there’s only one trigger on this gun), or it doesn’t.
          Saying one trigger pull performs two functions (I suppose you mean firing each “side” of the gun) doesn’t alter the fact that, legally, this is one gun (one serial number), and it fires two shots per trigger pull.

          I have no doubt the BATFE has somehow changed word definitions to make it legal. (Maybe it depends on what the definition of “is” is.)

          • Christian Hedegaard-Schou

            Why do you keep using the phrase “trigger pull”? I’ve quoted you the law. The law does not state anything whatsoever about trigger pull. Stop using that term.

            “By a single FUNCTION of the trigger”. This trigger activates two functions, not one. Each function fires a single bullet.

            Whether or not it fires one or a hundred shots per “trigger pull” is irrelevant because that’s not what is contained in the law.

          • MR

            One FUNCTION of the trigger activates two FUNCTIONS of the bullets.

  • Wetcoaster

    It has one slide, but two barrels and two firing pins. How exactly would alternating barrels work?

  • hydepark

    Not sure where the distinction lies, but ever since I saw the first images of this thing I have wondered how it could be classified as anything BUT a machine gun. Perhaps something internal which requires both triggers to be pulled? Because if only one trigger is pulled and both hammers drop, that’s a machine gun.

    • It gets around it because the pistol has 2 triggers that are linked together. So you are pulling 2 triggers for 2 bullets, therefore not a MG.

      • MR

        But if you only pull one trigger, does it still fire? I’m thinking I could put three triggers on my AR15, then install a three-round-burst fcg and autosear, and by that “linked trigger” theory, I should be legal. I’m not going to do that, and make sure to get approval from the ATF before you do, but it’s just a different means to the same end. Basically, as far as I can tell, this thing isn’t a machinegun because the ATF says it’s not.

        Brrr… did anybody else just get deja vu?

        • knightofbob

          I actually deleted a similar comment about bursts earlier.

          • MR

            As I said, I’m not going to do it. It’s obviously a very bad idea. But seeing the prices these 2011s are going for, there are apparently enough people out there with more money than sense. So we’ll likely be seeing triple-trigger AR’s on Youtube shortly.

      • hydepark

        Seriously not trying to cause an argument, but if you read your own statement, it only further supports the idea that it’s a machine gun at least to me (an admitted laymen on this subject). Two triggers linked together, linked sears, linked hammers, it’s all the same thing. Because they are linked, they are one part. Therefore, two linked triggers is ONE trigger. One trigger pull, two rounds equals a machine gun.

        Wasn’t there a double-barrel AR-type rifle mentioned some time ago that was just like this Arsenal? I wonder if it’s functionally similar at all?

        And also, full disclosure, I have no interest one way or the other in this firearm aside from technical discussion. I think it’s kinda ridiculous and I would never own one.

        • I think the fact that they are separate, but linked, is the crucial distinction. Two triggers, two sears, two hammers, two barrels, two magazines – essentially two complete firearms per two bullets.

          I handled one at SHOT and it’s pretty much two 1911’s welded together. The magazines are especially weird – two single stack mags joined by 1 baseplate.

    • GOT12

      maybe because anyone can see it is a semi auto

    • Aurek Besh

      Not knowing exactly how the handgun is set up internally, my best guess is that only the hammers are physically joined together while the triggers themselves act via separate linkages and sears. The hammer doesn’t drop if only one trigger is pulled (or they are pulled unevenly), since the other’s sear is still engaged. Only once both sears have disengaged will the weapon fire, which ensures the timing of ignition and the weapon’s legal status.

    • Ripley

      Think less of the definition of “function of the trigger” and more about “one shot”. In a single barrel shotgun the definition of a shot is a lot of bullets being fired from one trigger pull/function. Since these (.45) bullets always travel in pairs they could be defined as “a shot” seen together.

  • knightofbob

    a) It does fire two rounds with one trigger pull, and I’m still wondering by what technicality the ATF allows that. The COP derringers modified for Blade Runner are legally considered machine guns, for example.

    b) By surface area alone, two .45s are less than half that of what one .90 would be. For comparison’s sake, a 10 gauge is roughly .78 caliber. So, no, it is not evenly remotely like firing a .90 pistol.

    • Paul Epstein

      There are two trigger pulls.

      Because as anyone who has looked at the thing has realized, there are two triggers. Two triggers side by side.

      You need to pull both of them to fire two bullets. If you only pull one trigger, it will only fire one bullet (and while I’m not entirely sure, it probably wouldn’t cycle properly). If you pull both triggers, only then will multiple bullets be fired.

      There is absolutely no serious question as to why the ATF allows this.

      • knightofbob

        Ok, I hadn’t watched this particular video. The pictures and videos I’d seen to this point seem to show the trigger and hammer as respectively monolithic.

        There absolutely is a serious question as to why the ATF allows it, though. I’ve heard stories of Remington 1740 manufacturers getting in trouble for making a less refined version of more or less the same thing. Is the finger the linkage? From what I understand of the Arsenal double 1911, it won’t work if there’s even the slightest delay between chambers. So, either every shooter in these videos is so proficient as to pull two triggers at once, or there is some legal magicianship going on. I find the theory of judicial slight-of-hand more realistic, personally.

      • MR

        The last video said the hammers are fused together.

      • Bill Funk

        The triggers are linked; you can not pull one without pulling the other.

  • Ben

    A minor, usually unnoticed, hangfire when using this thing would turn into a very serious problem.

    • Giolli Joker

      It would turn into a jammed slide.
      It needs the simultaneous recoil force of two rounds to unlock.

  • Lee

    The last video I watched, showed that it had two triggers fused together. That’s one trigger for all intents and purposes, Machine gun it is. How is this not?

    • Christian Hedegaard-Schou

      It’s not because the BATFE said it wasn’t.

      • MR

        I haven’t seen Arsenal mention any ATF determination letter, maybe I just missed it. I would assume they’d be smart enough to check with the authorities before bringing these in, but you never know.

      • hydepark

        Well, I think while Christian may be right, I think that the rest of us are more interested in the technical and legal details of WHY the BATFE has come to this decision. I’m not interested in an argument, rather a discussion. I’m also not entirely convinced that this isn’t a machine gun, regardless of any BATFE determination.

        If it truly is not a machine gun according to the written letter of the NFA law, and the BATFE doesn’t think it is, that’s fine. I just want to know WHY. Reason being, I’m sure some firearm company could let their engineers go wild with a similar design that may allow something more closely resembling a machine gun to be designed and sold. Think the AN-94 (just add a second trigger right next to the existing one to make it more like the Arsenal 2011) or something in-between it and the Arsenal. Could this open up a world of two or three round burst weapons that don’t fall under NFA regulations? This is what I’m most interested in.

    • Ripley

      Because a machine gun is ra-ta-ta and this is kapow.

  • Jamie Clemons

    Neat novelty item but it does not really buy you anything. It would eat up your ammo quicker but do two bullets at once really gain you much?

    • MR

      You already answered your own question. “Novelty item”.

  • flwolf

    A magazine with double capacity would he more effective than a double-barrel. What’s the difference if I shoot 8 rounds trough one or two barrels?

    • Bill Funk

      This has nothing to do with practicality, but is rather an exercise in, “We can do it, so why not?”

  • E Morgan Schuster

    This is really just two guns joined together. If the connection between them is not permanent, it can be sold as two semi autos….not one machine gun. I’ll assume there are two serial numbers.
    I see only one use for this piece… on a set in Hollywood – maybe in a Dirty Harry sequel.

    • Giolli Joker

      The latest version, model Prismatic, 10 Auto, will appear in the next 007 movie, in the hands of Dave Bautista.

  • MR

    Whatever happened to the Keltec P333AT?
