5 Insanely Large Caliber Handguns


By Eric Nestor via wideopenspaces.com

We love pistols and we love huge calibers. Why not mate the two for some true Frankenstein-like guns? These guns are ginormous. Just how we like them. Out of Thailand (above), a 1911 single shot 12 gauge pistol loaded with buckshot? How about a .50 BMG single shot pistol with a monster muzzle brake?


This giant shooting Remington model 1859 replica will leave you speechless.


This homemade 11-pound 12 gauge chambered revolver was captured from a Brazilian drug dealer. It holds an incredible five shots of standard 2.75-inch shot shells. It is shown next to a standard-sized Taurus pistol for scale.


Then there is another massive 12 gauge homemade revolver. A picatinny rail on top and a forward grip adds to this awesome tacti-cool beast. This was confiscated reportedly from a Taiwanese man. We love how it says “Made in USA” on it.


There you have it, five giant hand cannons that just defy explanation. They are very interesting in a strange way and have an odd appeal. Those are some big ass guns but man…we kind of want one.

      “that might be some of the stupidest things i have ever seen.”

      You obviously don’t get out much.

      Life. Try and experience some of it.

      Warts and all.

    2. avatar Cliff H says:

      Three of the five fire 12 gauge shells in countries where the only ammunition you can find is probably for a shotgun. The giant Remington does not say what ammunition it is designed for, but 12 gauge would not surprise me.

    3. avatar kobs says:

      Agreed, except the first pic i’d love to try that one loll

  2. avatar James in MO says:

    How does the guy in the background of the 2nd picture NOT have a huge grin on his face? Those guns are all ridiculous.

    1. avatar Yellow Devil says:

      He was thinking about the cost of ammo.

  3. avatar uncommon_sense says:

    I love how the .50 BMG handgun has the word “Thunder” on the side!

    1. avatar General Zod says:

      I’m kind of fascinated by the recoil piston on that beast…

      1. I’m told it’s a nitrogen piston. You’d need one. The gun is a “thunder 50” I believe. I sort of want to shoot one… Probably only once though.

    2. avatar Geoff PR says:

      Didn’t Dyspeptic Gunsmith produce some data recently as to what would happen (as in how bad) if you fired a .50 BMG pistol?

    3. avatar Scottlac says:

      Oh good grief. Somebody made a .50 BMG pistol. Now that can be declared “armor piercing” pistol ammunition and banned.

  4. avatar The Mountain That Rides says:

    Oh good, they make pistols in my size now. I don’t need a tax stamp to get that 50 cal, do I?

    1. avatar Avid Reader says:

      IWB or ankle holster?

      1. avatar The Mountain that Rides says:

        Appendix carry, obviously.

  5. avatar Dracon1201 says:

    That drug dealer 12ga revolver is actually sweet!

    1. avatar Geoff PR says:

      That’s not a ‘drug dealer’, the PC term is now ‘Undocumented Pharmacist’.

      1. avatar NateGA says:

        Hahahaha…I about dropped my phone

      2. avatar Jon in RI says:

        Laughed my ass off! Classic

      3. avatar Noishkel says:

        *snickers* Nicely done. I’ll keep that turn under my hat.

        1. avatar Geoff PR says:

          I shamelessly stole it.

          I think it was Ann Coulter, but not not sure…

      4. avatar John says:

        a dope dealer is a dope dealer ,, guys standing at rite -aid and Walgreen etc are selling dope , the final result is the same

  6. avatar Tommy Knocker says:

    Back in the glory days, hunting tiger on top of Indian elephant required a Howdah pistol.

  7. avatar Ron says:

    And if someone actually fired the 12 gauge revolver with the forward grip what would happen to his fingers? One hopes he had no need for them as they would no longer be there.

    1. avatar General Zod says:

      Nah, the forward grip is well back from the barrel on that thing. Though there might be some blast to worry about between the cylinder and the frame…

      1. avatar Ron says:

        And it is the barrel-cylinder gap I was pointing to. If you’ve ever fired even the best handgun, think Freedom Arms, you would know how devastating that blast would be. Ruger had to discontinue their 357 Maximum Blackhawk as the blast was cutting the top frame apart.

    Your braking mi hart hear.

    1. avatar Hannibal says:

      Maybe the same person who wrote the NY “SAFE” Act.

    Shooting the Thunder 50

    1. avatar Gunr says:

      The car they were shooting, at the end is awesome! A couple gallons of “Bondo” and it will look new!

  10. Here’s a somewhat larger gun — it needs 79 men to operate it. Shoots 20 miles.

      Cool old video….thanks…

  11. avatar Ralph says:

    Wow, that guy with the Remington revolver must be really tiny.

  12. avatar Pantera Vazquez says:

    WANT……why? ………’cause.

  13. avatar anonymoose says:

    Franklin Armory has a drop-in 12 gauge conversion for Beretta 92s and Taurus PT92s. There is a version for 12ga flares that doesn’t have to be registered, and a steel version for shotshells that requires AOW registration.

  14. avatar Buffalo_Bob says:

    And not even a 3d printer required. . Where there’s a will, there is a gun

  15. avatar Southern Cross says:

    And I thought a .45-70 derringer was crazy.

  16. avatar DickDanger says:

    I’m I the only one impressed by the giant Bic lighter in the last picture?

  17. Note that the first two (pictures) are considered the only possible “sporting handguns” under the proposed ATF framework (that would have banned M855)

  18. avatar Hannibal says:

    “Only fired once!”

  19. avatar Billy says:

    Why oh why would someone mutilate a perfectly good 1911 like in the first picture?!?!?!?!!! There’s a special place in Hell for those blasphemers.

    1. avatar Matt in TX says:

      I like it! Want one.

      1. avatar ShaunL. says:

        I want one too.

    2. avatar Sian says:

      That was never a 1911 to begin with. It’s just a simple break-action 12 gauge made to look like a 1911.

  20. avatar John L. says:

    Boom, baby!

  21. avatar Raul Ybarra says:

    No boom today.
    Boom tomorrow.
    There’s always a boom tomorrow.

    Takes on a whole new meaning here.

    1. avatar jsallison says:

      Ivanova is god.

  22. avatar Former Water Walker says:

    Wouldn’t the 12ga.revolver work ok? What is a judge BTW? Isn’t a cruiser shot gun not so dissimilar? Not saying it’s fun to shoot…

    1. avatar Billy says:

      A Judge is chambered for the piddly .410 as well as .45LC. Nowhere near the 12gauge. Also, granted a cruiser shotgun with no stock would be a B! to shoot when compared to one with a true stock, still, it’s heavier and you utilize both hands.i fail to see how you could shoot the 1st revolver (the drug dealer one, I’m not counting the Remington New Army) without sending it flying over your head, maybe with a compensator and a sling like a S&W500. Looks to be more of an intimidation piece than anything. Attempting to utilize the fore grip on the second revolver, at least without gloves, would result in your hands catching blast from the cylinder… Then again, on second gland…maybe it’s high enough. I’d still prefer a stock myself lol.

    2. avatar NDS says:

      It would work fine, it’s 11lbs. 12ga is no joke but that heavy of a pistol is going to soak up some serious recoil.

      Now it would suck holding an 11lb pistol out in front of you all day, however.

  23. avatar Raul Ybarra says:

    Actually, I’d love to get hold of “Slippery” Jim diGriz’s .50 Cal recoilless.

  24. avatar mike oregon says:

    I’m still convinced that the F.A.L. pistol is the worst idea to actually go into production.

  25. avatar JohnF says:

    I stole this joke, but I can’t resist:

    “The world’s first crew-served pistols!”

    This proves that just because a gunsmith can do something, doesn’t mean he should!

  26. avatar Phil LA says:

    My reaction to the 12 gauge 1911:

    Holy shit taco

  27. avatar Russ Bixby says:

    Under the auspices of the Kansas 2A Protection Act, I’ve been Frankensteining a 7.62x54r 5 shot pistol; not an insanely large calibre, but insanely powerful for a handgun.

    Should be interestin’ once it’s done…

    1. avatar Phil LA says:

      Then the ATF will ban surplus 54R due to the whole pistol-armor piercing BS!

  28. avatar actionphysicalman says:

    When I had BCA build me a .475 Linebaugh back in ’98 I was pretty sure that I had gone full retard. As always, I was wrong, I wasn’t even half way there. Maybe if I trade in for a .22 short pacifier gun and pack that exclusively I can get back in the game.

  29. avatar Justin A says:

    how about a .600 Nitro express T/C Encore. warning some profanity in the video https://www.youtube.com/watch?v=gcZNY6vJhgc

    I tried 30-06 in an Encore pistol once…. that was enough

    1. avatar drew in michigan says:

      Got the chance to shoot a t/c in 444 that was some wrist breaking recoil – then got a brainstorm and grabbed my “bowling wrist support” after shooting up 35 rounds the guy said I had to pay for them, no problem i had a ball blowing up cinder blocks

  30. avatar Tyler says:

    Sad to see Buzzfeed style sensationalism and “list” posts here…

    “Will leave you speechless?”

  31. avatar wildman says:

    contrary to what women say- size does matter

  32. avatar scouch says:

    I want to see the concealed carry holsters for these.
