Frankenruger Mk II Kraut

TroubleshooterBerlin has designed yet another nifty gun upgrade. Being a fan of the classic MG42/MG59/MG3 design he decided to adapt them for the Ruger MkII .22 Pistol. It can take both Ruger MkI and MKII magazines. He initially wanted to just create a new grip, but decided to modify the internals. Internally only the hammer, hammer spring and sear are what remains of the factory trigger group. The ambidextrous safety now also functions as a bolt stop/release. I think it looks awesome.




I asked if this mod would be exported to the USA. He told me that because the changes to the frame are extensive, it would probably have to be exported as a firearm and this is to much of a bureaucratic/expensive task for him. Ideally this would be a job for a smaller manufacturer in the USA who has the ability to CNC a MKII frame from scratch. I hope a company picks this up. I want to shoot it!

    It would be great if they made of MkII in .32, .380, .25, Etc. and offered this grip on it. Like a non-cam lock Luger pistol

  • Eric S

    I really like how that turned out. Looks like something a Bond villain would use.

  • derfelcadarn

    This Ruger design is a nice pistol, but someone needs to get it to operate in 22 mag, then it will be a great pistol. The 22mag round is under utilized and a easily owned pistol in the caliber would help bring the price of ammo down to where yoiu could actually afford to shoot some. Definitely a volume thing

    • Blake

      or, people could stop snapping up all the 22LR at wally world & scalping it, & the situation would return to normal in a few weeks…

      • Amen to that!

      • gunslinger

        or they stop making 357 or 38 or 40or 10mm or 3006 or any of the “non standard (9mm, .45, .223, 7.62×39) and devote those lines to rimfire….

        oh wait.

    For some reason the fictional Krugermeier 2-2 from the Hitman Absolution video game springs to mind, great job!

  • strongarm

    Nearly a hundred years ago, another German pistol “Langenhann” had been designed
    with a very risky dismounting way, using a screw to retain the recoiling breechbolt. This
    is the second.

    If only my Mark III were that easy to take down.

    • You got that right!

      • gunslinger

        i finally broke down my MK2, and boy, it took me over an hour to get it back together. having that little spring pice in the middle of the grip… good lord.

  • Lance

    Looks awesome always liked the Ruger Luger like pistol. Hope you can buy us regular commentators one for Christmas.

      The Ruger is not a “Luger” copy, it is a copy of a Jap Nambu.

      • Or maybe both

        • David Sharpe

          Nope, the Nambu was influenced by the C96 broomhandle, the Ruger was a copy of a Nambu (Bill Ruger borrowed a friends war bring back and copied it.)

          • The Nambu does function more like the C96 rather than a Luger, but Bill Ruger imitated the Luger’s grip angle in his design of the Mark I rimfire pistol. The action is very Type 14 like though.

  • Beaumont

    Sort of a steampunk vibe. I like it. Surely some enterprising machine shop here in the States can turn these out.

  • schizuki

    I’ve always thought that a Ruger altered to look like its daddy the Nambu would be neat. Wood grips with horizontal grooves, maybe the winter trigger guard…

  • Amazing. I’m a luger nerd at heart, but I don’t have the cash for one. I doubt I would have the cash for this, but I can dream, no?

  • Blastattack

    Not sure why there would be much risk in exporting it. The upper receiver of the Ruger MK pistols is the firearm, not the frame. However, I am aware that you Americans have to deal with the idiocy that is 922r. Canada would not care however.

    • David Sharpe

      I hope they export to Canada, I want it.

    No, THIS is a FrankenRuger:

    14 rounds with no reload from a 6-shot cylinder revolver using a tubular magazine feeding fresh rounds into the rear of the cylinder and a gas-powered auto shell ejector. No other personal arm with the same feed cycle – ever. Magazines (so far) are either a short 2rd for holster carry (to autofeed behind five in the cylinder) or foot-long 9rd mags, and a 9 can top off 5 for 14.

    This guy is soooo smart I bet he could even reassemble a Ruger 22/45 mk III !!!

    I like to call it the Rugoo Namboo Voodoo
