The HK4: H&K's First Pistol (Four Calibers, One Gun)

The HK4: H&K's First Pistol (Four Calibers, One Gun)

Heckler and Koch made a name for themselves when they began producing rifles, but in the mid 1960s they decided to expand their product line to include pistols. The result was a caliber convertible, small handgun that could fire .380, .32, .25, and .22 cartridges by having the end user do a quick conversion.

The pistol was by no means groundbreaking, nor did it set the world on fire from a sales perspective, but it did lead to the company breaking into the lucrative pistol market.

    Isn’t that the stock pistol from Team Fortress 2?

  5. Miles K on July 22, 2022 at 7:43 pm

    My dad has one of these, pretty neat knowing it was HK’s first pistol and seeing the original manual.

  6. Rods Ahed on July 22, 2022 at 7:44 pm

    Have you ever noticed HK always puts a number in their gun’s names?
    Hk45, Hk p2000, Hk4..

  7. rclaughlin on July 22, 2022 at 7:45 pm

    Basically this pistol is a Mauser HSc made with modern manufacturing techniques.

    Great video. I never heard of The H&K 4. Very neat an interesting Firearm. I’d love to have this piece in my collection. I bet it’s pricy….

    Heckler and Coca Cola

    I’ve had one know for 30 years, mine is a 1972 Model. They were used by the Police in Europe I’ve heard. I really like the convertible caliber feature. This is still one of my favorite guns, it is handsome as the author stated.

  15. dmg12345678 on July 22, 2022 at 7:53 pm

    This needs to go back into production.

  16. Lance Hurley on July 22, 2022 at 7:53 pm

    I got one…how much it worth?

    Adorable

  19. Michael Hatfield on July 22, 2022 at 7:57 pm

    One of my all time favorite pistols. I own two and have all the caliber conversions. The .25 is my favorite and was the hardest to find but when I did I got 3 magazines with it. I fire .25acp and .32acp the most. I just love Heckler & Koch firearms.Great video as always.

  20. Browning35 on July 22, 2022 at 7:58 pm

    I had one of these with the .32 ACP barrel and .22LR barrel. Completely reliable in .32, it sucked dick in .22LR (and not in a good way…all teeth. Like cheese grater teeth, not playful biting with eye contact).
    I traded a guy in Dallas Texas for it approximately 12-13 years ago and I traded him a double stack Llama .45 ACP. Thought I got the better trade at the time, but the multiple malfunctions per mag with the .22 side of things really put a damper in things for me. Eventually sold it and while it was kind of an interesting gun I don’t miss it.

  21. THEBLOXIAN on July 22, 2022 at 7:59 pm

    look like a markrove idk how to spell it but yea

  22. E39M5SPEED on July 22, 2022 at 8:00 pm

    Nice pistol, thanks for sharing.

  24. roboliño schmidt on July 22, 2022 at 8:04 pm

    What a beauty

  25. Richard HL on July 22, 2022 at 8:04 pm

    The first pistol i ever owned. So so and I would never want to use it for CC

  26. Stray on July 22, 2022 at 8:07 pm

    This guy has very shaky hands. Makes me nervous.

  27. FieldShunt on July 22, 2022 at 8:09 pm

    I purchased one of these brand new in the early-mid ’70s. Convertibility has always been a weakness of mine (excepting the radial arm saw. Gads.) and this appealed to me even though I was only interested in the .380, a little, and the .22 versions.
    My recollections of the gun aren’t too favorable. I basically only shot the .380 and .22LR iterations; I can’t recall ever summoning the money to buy a box of either .32 or .25 (although I think I borrowed a few rounds of .25 FMJ from my then-father-in-law).
    It ran pretty poorly for me. Maybe I was missing some element of maintenance. The .380 setup was not a 100% runner at all, and that was with the factory ammunition of the day. Of course, the same applied to the .22LR and that ran only slightly better. That seems counterintuitive, but that’s what I remember.
    The trigger was absolutely gruesome. Hitting anything with the gun was beyond my skills in those days. Especially the double-action portion. At the time, I was a young and strong-handed carpenter and still that DA pull wore my finger out quickly.
    The SA trigger was unbelievably creepy. Maybe because my other guns at the time were 1) a Colt .45 (they’re called "1911s" now), 2) a S&W Model 28 .357, and 3) a Colt Detective Special, I did not grasp the nuances of the European trigger.
    I sold it for not much on the dollar. But of course, like so many Boomers, now I have an urge to relive my early adulthood by buying one off the Internet.
    And then I saw the prices! Good heavens!

    Hackler and coke

  29. Ant MAN on July 22, 2022 at 8:10 pm

    I bet that fireball lazer after firing it is what sold the gun

  30. whats really going on on July 22, 2022 at 8:11 pm

    sweet little gun

  31. Lance Hurley on July 22, 2022 at 8:11 pm

  32. JVT_RedBaron speaks on July 22, 2022 at 8:12 pm

    next time use your fingertip to pull trigger, not the middle phalanx.

  33. psikogeek on July 22, 2022 at 8:14 pm

    3:36 "…we’ll get to why that is in a second."
    ONE SECOND LATER: "You’ve got one for centerfire and one for rimfire."
    Truth in advertising.

  34. Mr S on July 22, 2022 at 8:16 pm

    Looks like a makarov. Nice.

  35. James Sunderland on July 22, 2022 at 8:17 pm

    Interesting

  36. n/a on July 22, 2022 at 8:17 pm

    Can tell you’re a bit scared of that slide bite. I would be too!

  37. LUIS LOYA on July 22, 2022 at 8:17 pm

  38. justanotherbloke on July 22, 2022 at 8:21 pm

  39. urankjj on July 22, 2022 at 8:23 pm

    I’ve got one in my pocket,(380) right now, but don’t tell anybody…….

  40. ServantToTruth on July 22, 2022 at 8:24 pm

    Noob Question: Why do guns have a flash (or bigger muzzle flash) at the muzzle on some shots but not all?

  41. Chris Harriss on July 22, 2022 at 8:25 pm

    A possible explanation of the French franc is a reference to the Jean-Patrick Manchette novel, "The Prone Gunman" which features an HK4 used heavily by the protagonist. The book was later made into a film starring Sean Penn, but did not feature the HK4.

  42. Stojce on July 22, 2022 at 8:26 pm

    it’s like a Makarov

  43. Billy Wallace on July 22, 2022 at 8:28 pm

    Really excellent review/info.
    About to buy one from a friend tomorrow with .22LR & .32ACP barrels.

  44. Florian Thomas on July 22, 2022 at 8:29 pm

    This gun make me think of agent Samson. "I love wearing a tux when I kill guys…kinda’ make you feel like James Bond"

  48. Stop the Philosophical Zombies on July 22, 2022 at 8:36 pm

    What is the retaining pin purpose? Why would you want to hold back the extractor?

  49. Joe Heinz on July 22, 2022 at 8:37 pm

    that’s a 380 ammo right ?
