Colt 1911 Machine Pistol

This one of a kind 1911 was made by Colt Industries and Swartz. It is claimed to be owned by @class3johnnie and it is transferrable. He claims he acquired it from the Colt Museum. It looks gorgeous.



Here is a video of him shooting it. I did not expect such a high rate of fire.

    It looks like the cycle rate is much to high to even be useful.

    • JustAHologram

      That’s why the infamous full auto ones from the 20’s and 30’s had custom extended magazines

      • jamezb

        yes, the mag FIRED looked to be a modern 10 round, while the one in the top picture looks to be 20 rounds or more. Sarco once sold 15 round and perhaps larger 1911A1 mags…

        • JustAHologram

          John Dillinger had 22rnd .38 super mags

    • Matt Taylor

      “Useful” is a very job specific term.

      • Drew Coleman

        Indeed. If I wanted a gun that could very rapidly turn money into noise, this would fit the bill nicely.

        • TheNotoriousIUD

          What do you want to do? Savor it?

    • BattleshipGrey

      But this is America, where not everything has a practical purpose.

    • TheNotoriousIUD

      Who said anything about useful?

    • If it scares the enemy into keeping their heads down and their tails tucked, it did its job. Worked a treat for the MG42, and .45ACP was a lot cheaper and easier to carry than 7.92×57.

  • Andrew Miller

    Paging Hiram Lebman…

  • TheNotoriousIUD

    Remove the stock, foregrip, flash hider and EDC.

    • AC97

      That’s not a flash hider, that looks more like a compensator to me.

  • TVOrZ6dw

    Californian and New York legislators must be dropping in their tracks with strokes just by printing this story. Oh the humanity!

    • Disarmed in CA

      They only print these to see me cry

  • Marc

    Should’ve been a .38.

    • Anonymoose

      Somebody did make a full-auto 1911 in .38.

      • Andrew Miller

        “Hiram Lebman”.
        He also managed a longer than 9 round magazine for them.

  • John

    Colt should have submitted this during WWII. Nothing about weight penalties now, is there?

  • Kenneth Wilkinson

    Field strip PLEASE! I need to see the internals on this beast!

  • It was designed by the same William L. Swartz responsible for the “Swartz Safety.”

    Here’s the patent for the machine pistol conversion:

  • Edeco

    I’m surprised at the lack of extended mags for (single stack) 1911’s. There are a few but they get lukewarm reviews or are only like 10 rounds. Should be relatively easy to get one column of 45 to feed. No need, you might say. Well maybe not but some 1911 owners seem to enjoy spending money and there are recalcitrant horse’s-butts like me who want >10 because we were once told we couldn’t have it and were traumatized.

    • Gregory Markle

      The spring you would need to lift all that weight would make loading the damn thing a real joy at some point!

      • Nicholas C

        No really. The SGM tactical 30rd .45 acp Glock mags work great and the extended Kriss Vector mags work well too.

    • iksnilol

      Get a doublestack 1911, problyem solved.

      • Edeco

        Nyet, ended up going with an FNX45. Found it better to start with a clean-slate design; no farting around about whether it will hack +P, lighter, grip more to my liking + a gift-basket of modern assault features such as threaded barrel.

        • iksnilol

          Why should a doublestack 1911 like a P14 have problems with +P ammo ?

          • Edeco

            Last I checked Paras weren’t explicitly +P rated. I’m sure they can handle it, you could say that’s just words, but given the choice in a new product I’d rather the manufacturer say it.

      • Jake


        • iksnilol

          Ne, is problyem, comrade.

          We have problyem now?

          • Jake

            problem* problem*

          • iksnilol

            You’re a poopyhead.

            There! I said what we all were thinking. HAPPY NOW!? Ban me for all I care, THE TRUTH HAD TO BE REVEALED!

      • John1943

        And a different one created. I have no problem concealing a full sized 1911 under a tee shirt. A double stack? Meh!

        • iksnilol

          Double stacks are thinner.

          • John1943

            Which ones? Measurements, please.

    • Bill

      I sometimes carry 10 rounders for spares when I’m carrying a 1911.

      • John1943

        So do i

  • DaveP.

    There were at least two others. The .38 Super machine pistol conversion that Dillinger used and I’ve seen pictures of a fighter pilot with one in the Mighty 8th Air Force museum.

    • Andrew Miller

      Hiram Lebman.
      Look him up.

      He made conversions in both 45 and 38 Super.
      Though he was supposedly under the impression Dillinger was merely a wealthy businessman.

  • Broz

    A number of years ago and older gentleman (in his 90s) came to our collector’s meeting in FL with a bag of parts to make a 1911 full auto…he told us that he worked for Colt just prior to the War and this part of a was a one-off experimental attempt to manufacture a conversion kit for the 1911s in use by the Army…shortly after the parts were made the War broke out and Colt quietly abandoned the experiment…he had (so he said) the only known parts still in existence…this vid would tend to refute the claim that he had the only extant parts, but also support his claim that Colt WAS working on a F/A 1911 convwersion.

    • jamezb

      Both could still be correct: Perhaps his set was the only “unassembled kit” and perhaps this completed gun was built up by Schwartz rather than Colt, and presented to Colt as a prototype test sample?

      • Broz

        Thanx, my friend…sometimes you see/hear things and wonder if the folks showin’ it/them knows what he’s talkin’ about…this shows the evidently our guest speaker DID…

      • William Swartz was a Colt employee.

  • So is the power of the Swartz that Yogurt was talking about?

    If you do not know the movie, I pity you and your sad existence.

    • ostiariusalpha

      “I see your Swartz is as big as mine.”

    • PK


      The flamethrower! The kids love this one…

  • Phil Elliott

    I’ve seen a .45 “go full auto” after some less than knowledgeable people worked on it in an attempt to lighten the trigger pull. Fortunately it only had 5 rds in it as it was to be used in a Bullseye match, last round damn near went up his nose.

  • Avid Fan

    I was under the distinct impression that these were not terribly uncommon. Seems I remember something about a 20s or 30s gangster having some made.

    • The difference is that this was a factory Colt experiment, not aftermarket.

  • Fruitbat44

    Random observation: it looks really dieselpunk.

  • Sasquatch


  • claymore

    It’s the real thing. I saw this one or one like it in the vaults when one of our retired guys was head of LE sales and I got a private tour.

  • PK

    That’s not the only pre-86 1911 conversion in the registry, but it sure is interesting. Most of the others I’ve seen have a different front grip or none at all, and only one had a notched mainspring housing for a stock like that. I never tire of such entertaining guns!

  • DanGoodShot

    Whats the story behind this lead spitter? You know, why was it built? When was it built? For what reason was it built? Rate of fire?(clearly very high) More deets man!

  • Voice_of_Reason


  • valorius

    it would look better with a tommy gun VFG, but still very cool!

    Speaking of tommy gun VFG’s, has anyone ever offered one for the AR-15?

  • Archie Montgomery

    I’m not surprised at the rate of fire; handguns have a very quick ‘recovery’ time. I am surprised at the control of recoil. Then again, the full auto pistols with which I am familiar are typically stockless – actually handguns.

    Interesting technical exercise.
