A Guy Walks Into a Gun Store . . .

HK FN (courtesy The Truth About Guns)

And wonders why this gun doesn’t work. [h/t You Know Who You Are]


  1. avatar Tom in Oregon says:

    Coffee all over my desk

  2. avatar A samurai says:

    What the holy hell am I looking at!? How the hell did they even get an HK slide on an FN frame…. And how do you get it off again? That’ll be the fun part. Getting the slide back off.

    1. avatar peirsonb says:


      1. avatar A samurai says:

        Polymer frame + BFH…. sounds scary to me.

      2. avatar Paul%# says:

        I prefer BMFH, but that’s just my tool box.

    2. avatar Erin says:

      No answers, man. But if you spend enough time in a gun shop you learn to stop asking and just tell them they’re stupid.

      1. avatar Russ Bixby says:

        Are we both armed Linux peeps, or did you “borrow” my av?

  3. avatar peirsonb says:

    The zeroeth law of gun safety: RTFM.

  4. avatar Howdy says:

    Those actually fit together? Wow

  5. avatar General Zod says:

    I’d say they’re damned lucky it didn’t work…

    1. avatar Andrew says:

      Ding. Winnah!

  6. avatar BLAMMO says:

    I confess I don’t really know my guns but I see an H&K logo on the slide and what looks like an FN logo on the grip.

    So, I’m going with it having to do with that.

    1. avatar Chris. says:

      That’s the FN 5.7 frame, HK USP 45 slide…

      My question – what barrel was in it?

      1. avatar A samurai says:

        Had to be the 45 barrel. The 5.7 barrel would not lock up… Locked up… thats how you describe this.

        1. avatar LarryinTX says:

          Remember now, it didn’t work. Maybe NO barrel?!

        2. avatar Dusin says:

          locked up is how id punish this

    2. avatar A samurai says:

      That is an HK USP 45 slide on an FN Five Seven frame.

  7. avatar fiun dagner says:

    I’m looking at this on my phone so it’s kind of hard to tell, but is that an H&K slide on an FN frame?

    1. avatar Rob Aught says:

      It is and I am trying to figure out how the hell they did that.

      1. avatar A samurai says:

        Wait. USPs are Hammer fired…. Aren’t Five Sevens striker fired? I cant figure out how they did that either. And I once got a Glock 21 slide on a Glock 30. And back off again. On purpose.

        1. avatar BillC says:

          FN FiveseveN’s are hammer fired, it’s just concealed. They are single-action.

        2. avatar LarryinTX says:

          Yeah, you CLAIM it was on purpose!

  8. avatar TheOtherDavid says:

    Well, when an FN and an HK love each other very much….

    You carry it in a Crossbreed Holster?

    1. avatar Billy says:

      HA!! +1000 for the “Crossbreed” comment

    2. avatar DJ9 says:

      Winner of the Internets for the day!

      Thanks for the laugh!

    3. avatar Another Robert says:

      Yup, bullseye!

    4. avatar A samurai says:

      … or are both very drunk.

    5. avatar bill says:

      That’s very good.

    6. avatar Tom in Oregon says:

      Best comment of the week, and it’s only Monday!

    7. avatar Wayne C says:

      Spot ON!

    8. avatar The average American says:


    9. avatar TheOtherDavid says:

      Thanks everyone, it’s Monday and I’m fully caffeinated – I can’t promise witticism like this by Friday!

    10. avatar Paul53 says:


    11. avatar Colonel Panic says:

      I would say an “Inbred Holster”. That gene pool needs some chlorine!!!

    12. avatar Cockatoo says:

      ^ THIS!

  9. avatar Dracon1201 says:

    I thought it actually looked really good! I did just lose Pepsi over the counter. My coworkers are very confused.

  10. avatar Cdphil says:

    It is a pretty good looking gun…

  11. avatar Cameron S. says:

    The new FK Five-USPN, chambered in the new proprietary 45.7 caliber.

    MSRP – $3499.95

    1. avatar Andrew says:

      HK and FN Announce new small-arms global venture.

      The co-branded company, FKHN (pronounced “Fuh-Kin”) Will produce high-level small arms for Military and LEO around the world.

      Their initial pistol, the FKHN .45, will surpass all other current .45 platforms in both price, maintenance, and stature among firearm users.

      1. avatar Wayne C says:


      2. avatar Chris J. says:


      3. avatar Paul%# says:

        FKHN awesome!

      4. avatar Pulatso says:

        Aaaaand we can all go home now, we have a winner.

    2. avatar Bigred2989 says:

      Because you suck, and we hate you.

      1. avatar Ing says:

        So now their unofficial slogan becomes “Because we FKHN hate you, and you suck.”

    3. avatar gearshiv says:

      Think your missing a zero in there

    4. avatar racer88 says:

      Winner! LOL!

    5. avatar LarryinTX says:

      More correctly, isn’t that the 45.7mm caliber?

  12. avatar Rokurota says:

    What’s more, it’s a .45 slide on a 5.7 frame. Throw a .9mm barrel in there and Bob’s your uncle.

    1. avatar Gunr says:

      How about a 45 cal. barrel that’s only been bored out to 9MM at the muzzle?
      Firing it could be a life changing event!

      1. avatar BillC says:

        I don’t think you get the joke.

        1. avatar Rich Grise says:

          I don’t think _I_ get the joke. How can a .45 barrel be “bored out to 9mm” when, if my arithmetic is accurate, 9 mm is only about .354″? Isn’t a .45 already .45″? I know I’m practically a gun virgin, but come on!

          As to how gun-naive I am, I didn’t even spot the different logos; I was looking at all the levers and buttons and gewgaws and gimcracks alongside the rail.

        2. avatar peirsonb says:

          Same here. My first reaction was “The safety’s on.”

      2. avatar LarryinTX says:

        First off he did not say “9mm”, he said “.9mm”, which should clear things up since it makes everything possible. “Boring out at the muzzle” refers to standard interactions between guns from differing makers, reviewed over and over until we’re so bored out we want to eat the muzzle. Even the famed .9mm muzzle.

    2. avatar Felix says:

      More like Bob’s your Aunt Sally.

      1. avatar Skeptical_Realist says:

        This made me laugh more than it should have.


  13. avatar Del says:

    True story.

    Customer has a GLOCK chambered in .45 GAP, .45 ACP ammo, and a G17 magazine. His “new to him” gun wouldn’t work……

  14. avatar danthemann5 says:

    Looking at that picture actually made my head hurt.

  15. avatar Texheim says:

    Those are 2 high end guns to possible screw up….

  16. avatar OakRiver says:

    What sorcery is this?

    1. avatar SouthernPatriot says:

      That’s exactly what it must be.

  17. avatar Cknarf says:

    I think it looks kinda cool lol.

  18. avatar JasonM says:

    Is it sad or good that I picked up on the mismatch by noticing the mag release wasn’t an HK one before I noticed the FNH logo?

    1. avatar ShaunL. says:

      I noticed the parts LONG before I noticed the logos as well.

    2. avatar DJ9 says:

      I’d say “good”. Many firearms types/brands have a key like that; years ago, I used to be able to ID the vast majority of shotgun brands by looking at the mag tube cap.

    3. avatar LarryinTX says:

      I didn’t notice either, looked fine to me. Shows how much *I* know!

  19. avatar A-Rod says:

    When he walked into the LGS was he pointing the gun sideways, you know …thug/gangsta style?

  20. avatar Great Scot says:

    Kinda cool, but I doubt that that’s functional. Crossbreed holsters…Funny!
    I think that the coolest combo would be a USP slide on a Walther P99 frame.
    Hah…Crossbreed…Just can’t stop laughing about that!

  21. avatar Timoteo says:

    I wonder if he got it on craigslist?

  22. avatar supergrover says:

    has no magazine

    1. avatar EK says:

      The Kimber single stack magazine would not fit

  23. avatar Jeff says:

    How did he get that together? Did he follow the old mantra of “if it doesn’t work, force it?” LOL Good Lord…

  24. avatar SouthernPatriot says:

    Now, that just isn’t fair, I had my coffee just the way I like it (in my cup!), now, it’s not.

    How’d he (or they) get the slide on there? Maybe a better question now, how do they get it off? That is just insane.

  25. avatar Jeff says:

    Talk about the double take of a lifetime! I remember when Glock sued S&W over the Sigma line in the ’90’s. There was an article in one of the magazines (I believe Guns & Ammo probably around 1997 or 1998) on the similarities of the two weapons. The author was actually able to swap slides and the guns worked perfectly.

    That being said, I think this guy missed the mark . . .

    (On a flip note, it does look cool!!!)

  26. avatar Zak says:

    The last time Germany invaded Belgium it looked something like this too.

  27. avatar DanRRZ says:

    Holy FrankenPistol!

    I cocked my head sideways to take in what was going on there, I must have looked like a dog captivated by a piece of bacon.

  28. avatar Tim Freeman says:

    Teutonic rune magic

  29. avatar Zack says:

    Haha… I could write a book on some of things I have seen come through our doors at http://www.shootersplus.com/. One that stands out the most is a guy that brought in a really nice “expensive” turkey hunting shotgun and couldn’t figure out why he wasn’t even on the paper when sighting it in. A quick look down the barrel and it was painfully obvious the barrel was bent. A couple questions later we find out that when riding his fourwheeler to his hunting spot he hit on a low hanging tree limb!

  30. avatar Skully says:

    Nevah been dun befoh….

  31. avatar Ross says:

    Now that’s just funny.

  32. avatar Ardent says:

    I suspect this abomination was constructed for fun in the gun shop (we do screwy things at my LGS all the time). Otherwise this is inexplicable unless the owner keeps random gun parts in a box and assembles them into a gun as needed. How else could this have happened?

    Another take: You got FN in my HK! No! You got HK in my FN!

    One more: Somewhere there is a guy with an FN slide on an HK frame wondering what the hell happened.

    1. avatar Drew says:

      What happened was the inevitable consequence of colon carry in condition tactical butterscotch for both your primary and BUG.

  33. avatar Roll says:

    Sooo who would we send this to to fix?

    1. avatar Drew says:

      Hi point? They never ask questions nor pass judgement.

      1. Send it home to Mother! Hee hee hee! 😀

  34. avatar Merits says:

    I thought guns without magazines weren’t very dangerous, and really don’t ‘work’.

  35. avatar jsallison says:

    Now if I can just get my 1911 slide on a Beretta 92 receiver. Would go well with a bullpup levergun.

    1. avatar LarryinTX says:

      bullpup levergun. Now, THAT causes a mind picture that hurts.

  36. avatar Matthew says:

    That’s a very expensive paperweight if the slide can’t be removed!

  37. avatar Steve Truffer says:

    …The fuck?
    That actually looks pretty sharp.

  38. avatar chris says:

    photoshop for the win!

  39. avatar Pulatso says:

    Clearly all that is wrong is that the takedown pin has not been properly reinserted.

    1. avatar LarryinTX says:

      That’s simply because they did not have a big enough sledge hammer.

  40. avatar boardsnbikes says:

    Those magicians at Sons of Guns can do ANYTHING!

  41. avatar S.CROCK says:

    Who has money for guns that expensive but has the firearms know ledge of a politician!?

    The weird thing is it almost looks like it fits.

  42. avatar Excedrine says:

    How did he even do that!?

  43. avatar Russ Bixby says:

    Wow. Just – wow.

    I’m thinking that had it worked at all, it should have been as a grenade with a 2 millisecond delay; glad it didn’t.

    Maybe FPS Россиа can figure out how to get it apart again…?

  44. avatar Clay says:

    Not nearly as short on money as brains

  45. avatar Skeptical_Realist says:

    1st thought: Wat?

    2nd thought: Even this is prettier than a glock.

  46. avatar GuyFromV says:

    Yeah, I’ll admit it looked weird with the slide/frame mismatch but it was the “no magazine” aspect that really jumped out at me. I thought I might have been concentrating on the “too obvious” for a while…but thinking about how this guy even attempted to chamber a round to discover it didn’t work without a magazine scares me.

  47. avatar borg says:

    Assuming you can get it stripped all that is needed is the completed slide for the FN and the frame for the H&K

  48. avatar Michael says:

    Probably the new Taurus, they just make copies of S&Ws and Berretta’s .
    Imagine how much it would cost.

  49. avatar Ross says:

    Ah… the new FN Forty Five Seven, got to get me one.

  50. avatar Cockatoo says:

    STILL a better love story than “Twilight.”

  51. avatar Paul B says:

    I’m wondering exactly what he tries to put in it to find out it didnt work. 5.7? .45acp? 9mm?

    Screw it. Force an AK mag into the well and call it a day.
