^^^^^
This is the truth. James knows more than anyone on the P7, he's gone through all my P7's before I shot any of them. You'll never talk to a nicer fellow either.

I carried on duty and shot a lot with my P7M13. Practice was Nato 124 fmj, carry was 9BPLE, never even had a hiccup. I forget round count, but was north of 15k.
Another in the long line of stuff I never should have let go.

Question for you: Why did you choose NATO 124 gr FMJ for practice, as opposed to the many choices of other 9mm range ammunition? Reason I'm asking, I have a strong feeling that I read someplace that this was the prevalent ammunition when the P7 went into duty for police use in Germany, and the pistol was designed to function well with this ammunition, but I cannot remember where I read this.

That is really the question that I was asking when I started this thread, so any light that you can shed on it would be helpful.

as you know P7 was a German police pistol, P13 is just his husky brother
why I chose the two loadings, simple, I was able to get them in quantity for prices that younger me with much more disposable income thought was a hell of idea. buy (somewhat) cheap, stack deep.

At the time my parents had no idea what was stockpiled in the back of the basement.

P7s have very specific tolerances when it comes to the gas piston diameter and the gas chamber.

In an effort to scrape the carbon off the piston and from the gas chamber, some people have been overly aggressive with cleaning and have opened up the tolerances. If this is a used gun with no provenance, you may want to send it in to James to give it a once over. He will make sure that everything is good to go.

I had same problem with a used PSP when I first purchased it.

Resolved the problem with an Ultrasonic cleaning to clean the gas chamber and piston.
No further problems.

By chance are you shooting reloads, professional or otherwise, or ammunition that has a reputation for being dirty (Remington green box for example)? I ask because years ago, while shooting with a friend who brought his duty P7M13, his pistol went down with commercial reloads. It was very dirty ammo. After cleaning it at the range and switching ammo, his gun was flawless. OTOH, my W. German P228 handled everything flawlessly. As I recall, he stayed with quality commercial ammo after that and never had any problems.

If you are not shooting dirty ammo, the gas cylinder could be dirty itself. You may want to carefully clean it.

If all else fails, as mentioned, send it to James. He is the accepted guru on a HK oriented forum I visit from time to time.

Sounds like your P7 gas chamber is dirty.
Soak it and scrape it.

Got to admit, my 5 P7’s and M8’s have never malfunctioned. Ever. Nothing to add.

The only problem I've had with my P7 was the elbow spring--part # 29 in the parts diagram. The elbow spring was not in it's correct position.

When I owned a P7M8 and a P7N13, I shot 124 grain and never had a problem.
