1. Hk Serial Number Prefixes

I recently bought a late-model H&K P7M13 from a dealer in Switzerland and thought gunnit might like to check it out.Main difference from earlier models is the HK Sidearms GmbH marking; the earlier models were marked with the company's earlier name. This one has no import marks (not even CH-prefixed import marks like recently manufactured USPs coming into Switzerland).What I like about the P7's despite their being discontinued in 2007 is the low bore axis on it and the feeling of quality with it, even compared to my USP. Where the USP was made for multi-calibres, the P7 was really uniquely made around the 9x19 Parabellum cartridge, and it shows.It's the one gun I feel H&K was a long way ahead of the curve on; it's striker-fired, has a gas action that's now making a comeback in the recently released Walther CCP pistol, has a low bore axis that helps reduce muzzle jump and helps with follow-up shots and has a fixed barrel that lends itself to high accuracy even for a short-barreled pistol.While there's still plenty floating around, they're going to become more and more rare. My P7M8 is from the first few hundred made and this P7M13 by virtue of its date code is likely one of the last few hundred made. Bookends on the life of an interesting, if under-appreciated gun (thanks to its high price).I've included the obligatory H&K incorrectly loaded magazine pic. You may know this but you were so helpful to me with the S&W model numbers:The P7 uses a gas port in the barrel to push against a piston separate from the barrel that pushes against the slide's rearward momentum to effect the gas delayed blowback. (the port is just ahead of the cartridge case, the chamber is below the barrel and the piston pushes towards the front of the gun against the lower portion of the slide).The Steyr GB uses gas ports in the barrel (towards the end of the it) to use the gas pressure to lock the barrel itself to the slide.

(multiple ports fill the space between the barrel and a 'chamber' milled into the slide to lock them together). This is known as the Barnitzke system. Effectively the barrel is the piston and the slide is the cylinder.The HK P9S is a true 'Roller Delayed-Blowback' pistol that works just like the HK 91/3/4/etc rifles. The rollers slow down the rearward movement of the bolt carrier and slide. They are never locked as a unit.Not to be confused with the CZ 52 'Roller Locked' mechanism that also uses rollers but works slightly differently. In the CZ 52 the slide, barrel, and locking piece are locked together with the rollers for a short duration.I like different mechanisms.

I picked up my 13th HK P7 in Lodi this morning, a NIB P7M13 with 'IH' (1987) datecode, and decided to take photos of them all, grouped by model.First up, the one that started it all, the P7 PSP. My 'IA' (1980) one has been hard-chromed by Tripp Research, but my 'IC' is blued.the P7M8. I have a pair of consecutive serial-numbered Jubilees (in the foreground). The other two are 'KF' (1995) models, one of which was hard-chromed by Tripp Research.P7M13 comes next, and represents the first P7 that broke away from the single-stack paradigm. The one I picked up this morning is on the left. I had my 'KB' (1991) one hard-chromed by Tripp Research.

The other is a 'KD' (1993) model.the.40 Auto cartridge rose to popularity, the P7M13 was retrofitted to handle it, with a slide of much greater mass. Note that my blued one, with a 'KC' (1992) datecode, is the 101st made, based on its serial number. It is also one of only 1,000 or so made, in terms of blued models. My other one is also a 'KC' model, and was originally in factory nickel. I had that stripped off, then hard-chromed by Tripp Research.http://www.praxagora.com/lunde/photos/two-p7m10s.jpg. Someday I'd like to get one of those P7's.

Have held one at my local gun store and it felt very solid.BTW, the quality of your pictures is outstanding! I'm gonna have to upgrade to a better camera.You'll need to pick up the pace on that dream - the P7M8's out of production now, and falls off the 'safe gun' roster later this year, and then you'll be stuck with whatever you can find used, in the state.

Hk Serial Number Prefixes

(assuming you're still in CA)I'd been itching to get one since a HK Day at Targetmasters, and finally got around to ordering one in from NJ this week. It should arrive at Irvington Arms next week, and then just 10 more days 'till it's mine!:D. You collect P7s like I collect S&W N-frames.Only at 6 N-frames currently but that will one day change with 4-5 other guns still on my purchase list.I do want an HK P7 though, it's the one gun from HK that I think warrants the price. Sweet little gems of guns, great triggers, point very well, and accurate to boot.I've been a 2 gun person for a long time, 1911s and N-frames. But I do want an HK P7 to add to the collection, I'm just pissed I never got one back before Jan 2000 so I could have gotten a M13 with several mags. I have heard mixed 'things' about Nicks.

Have you any experience with him other than transfers? I'm not trying to stir the pot, just looking for someone who may be able to take a look at my registered HK91 clone for some mag-well/feeding concerns.It seems that with the onslaught of new AW registration, even some 'in-the-know' gunsmiths are hesitant or weary to look at anone's black rifles; when in fact it's perfectly legal for them to work on them while the weapon's owner is in house. Just what the banners wanted.p.s.

Beautiful pistolas, Doctor!-gloxter.
