H&K P7 PSP Field Strip

The H&K P7 series of handguns were in production for 30 years and are coveted by many. These unique pistols function via gas delayed blowback and are just a dream to shoot. While they certainly look unconventional, the P7 is a West German wonder-gun that everyone should get some trigger time on at least once. So lets take a look inside!

– [Voiceover] Hey guys it’s Alex C with TFPTV and for today’s field trip we’re going to take a look at a Heckler and Cook P7 PSP, the P7 PSP is the first model of the famous HKP7 squeeze-cocking series of handguns and to many these just look bizarre In many ways they are actually they aren’t a locked breach which is strange for a nine millimeter handgun They were also very expensive when they were introduced, HK had to actually release an ad explaining why the P7 was so expensive as seen here, you can look at that on Google if you want to, but you know some people may not like these from an aesthetic standpoint but I’ve always thought that they kind of are charming in their ugliness but I digress, so anyways, let’s first check the chamber we’re going to draw the slide to the rear make sure there’s not a round in there remove the magazine and then to get the field tripping process you’re going to want to squeeze the squeeze cocker and return it to battery.

Now there’s a button located to the rear of the gun and you’re going to press this button while pulling the slide rearwards up and forward.here you can see Now here you can see that piston in there, the piston actually delays the open ending of the breach basically there’s an area of the firearm that’s tapped where gases work against this piston to delay that which is kind of interesting, kind of cool.

Really that’s all you have to do to field trip and HKP7, they’re very simple handguns from a maintenance standpoint, they are complex in the squeeze cocking mechanism and all that I can show you that in a future review video if that’s something you’d like to see but this gun rides everywhere with me it’s my carry gun, it’s always usually either on me or in my briefcase, so it’s never more than ten yards away from me or so.

As an optional step you can also remove the striker assembly with a little tool that’s included as seen here this is an aftermarket one because it’s a little nicer but pull the squeeze cocker just a little bit, press it in to the recesses rotate clockwise and it comes right out of there.

Now there were many variants of the P7 perhaps the most iconic and most desired would be the P7 M13, the M13 was an improved version, you’ll notice it’s got a magazine release in a more traditional place as opposed to a heel release and it’s also got a 13 round magazine so you’ve increased your amount of rounds you can carry in the gun also you can remove the striker assembly without a tool, you just press that and rotate and it pops right out of there.

But the P7 M13 was actually entered into the trials to potentially be America’s service handgun along with the M9 and Cigs Offering and so on and so forth but it wasn’t to be, it was a very expensive handgun and yeah I guess the military trials favored the M9’s cost and other factors as well but I hope you enjoyed this brief breakdown of what I would consider my personal favorite handgun, they’re just phenominal they shoot very well, they’re incredibly accurate and I really do plan on doing a full review soon, big thanks to Ventura Munitions for providing ammunition for our shooting videos thanks for watching.

      yippee-ki-yaya, Mr. Falcon!

  • Slim934

    Does anyone make a clone of any of the P7 iterations?

    • SirOliverHumperdink

      No. I wanted one until I fired one, weird having to squeeze it and pull the trigger. The NJ State Police had them and eventually got rid of them- after 18 years!

    • DW

      No, but the system lives on in the Walther CCP

      I had a gas-delayed blowback 9mm once you probably never heard of, and there’s a good reason for its anonymity. The Heritage Arms C-1000 ‘Stealth’, compact polymer framed 9mm semi-auto pistol.

      On paper this was a great little pistol, damned cheap, light, small, 10 shot mag, fixed barrel, glock style half-cock striker fired. But it had a fatal flaw.

      Unlike the Glock which has very generous cutouts between the frame and the slide, the C-1000 had a more conventional gap. Sure it looked nicer, but when the pistol warmed up, which was pretty quick because of the gas-delayed blowback action, the frame would warp just enough to tie up the slide into an impossible to clear stoppage. The only fix was to wait for the frame to cool down and return to shape.

      If you fired slowly enough, this stoppage would occur after the sixth shot. If you fired quickly you could get off the whole ten round magazine before the pistol would seize up. Guess that’s why they only supplied one magazine with the pistol!

      The magazine seemed based on the Browning Hi-Power magazine. Which makes sense because I believe the design originated in South Africa. You could fit a Hi-Power mag into the pistol and it would feed every round but the last in the magazine before engaging the slide stop. Odd.

      This was a cool gun design, and I had high hopes for it. But it was a failure in execution. Too bad. It seems like a few tweeks to the design could have fixed it and made it into an excellent handgun.

      • The Heritage Stealth was based on the South African ADP designed by the Rhodesian expat Alex Du Plessis. Tanfoglio marketed the ADP for a time in Europe, and it was even marketed here in the US by Wilson Combat.

        • gunsandrockets

          Did the ADP have the same problem with jamming?

          • Don’t know. I’ve never known anyone with a genuine ADP.

            One bit of ADP trivia was that Du Plessis had developed a 9x19mm cycle length .45 cartridge, the .45 ADP, years before Glock introduced the .45 GAP.

  • janklow

    love my P7. such a neat handgun.

  • Steve

    My first semi-auto carry gun, and one I will probably never get rid of. I actually bought a second one just to harvest some discontinued parts from the early models before getting it refinished.

  • SirOliverHumperdink

    Geeze dude, where are you getting the bread for these toys?

    • Mr Silly

      He has guns- he walks into stores and they hand money to him as gratitude for his videos?

  • David

    I just bought a P7M8. What a cool gun!

  • ostiariusalpha

    They aren’t necessarily beautiful pistols as they come from the factory, though I find their appearance rather charming as well, but put some fine walnut grip panels on it with a solid nickel or two-tone finish and the P7 compares very nicely against other compact pistols like the Walther PPK in the looks department.

  • TheUnspoken

    Great article, the P7 is such an interesting design, it would just be a curiosity for the dustbins of history if it didn’t shoot so nicely! I waited and missed the steals on police imports a couple years back, finally got a pair of p7 psps and a p7m8, awesome guns, shouldn’t have waited!

  • Bill

    I had a PSP and let it go, and have no idea of why. I’ve done plenty of stupid things, and that ranks near the top.

  • Spencerhut

    I shot a P7K3, P7M8 and P7M13 on the same day side by side and the only one I even sort of liked was the P7M13. Recoil on all of these guns was excessive for the caliber. The P7M13 spread the recoil out a bit more so it was not all that bad. The trigger pull was sort of . . . mush . . . mush . . . (is this thing going to fire or what?) . . . . mush . . . bang! On all of them. Not a fan. Over rated and overpriced German tinker toys.

  • plumber576

    What you have there is NOT a “PSP” it is just a P7. If it was a PSP it would be marked as such on the slide and is a HIGHLY collectible and rare firearm.

  • There was also the Network Custom Guns “Gas Gun” conversion for the M1911 frame.

  • FWIW: The HK P7M13 was terminated from the JSSAP pistol trials because it failed the reliability and corrosion resistance requirements. HK never reached the bidding stage, so the issue of the P7M13’s price never came up.

  • Spencerhut

    So it’s just like it but different? Got it.

  • Slim934

    I actually bought a CCP not long after Inrange TV did their little breakdown of it. I like it but I just wish it was as easy to break down (and used a more standardized sight cut) as the P7. The CCP to me seems unnecessarily difficult to open up.

  • Michael R. Zupcak

    I had a Playstation light gun modeled after this in the late 90’s. I didn’t know the reputation it had until it was referenced in one of those Jack Reacher books (Echo Burning, I think). Everything that was said about it in the book was accurate, including the fact about the Army trials and the P7M13 model with the increased capacity in 9mm. There was also a P7M10 in .40 S&W.

    Any idea as to why we don’t see more gas-delayed blowback pistols or subguns on the market if this one shoots so well?

  • Phaideaux

    Alex, what holster do you use to carry the P7?

  • Kristoff

    “…coveted by many. These unique pistols function via gas delayed blowback and are just a dream to shoot. While they certainly look unconventional, the P7 is a West German wonder-gun that everyone should get some trigger time on at least once.”

    I love a good puff piece every once in a while.

    “… I guess the military trials favored the M9’s cost and other factors as well”

    Other factors as in its a damn good gun?

  • Mr Silly

    Nice gun. Good article
