    How necessary is the gas cylinder scraper tool and the firing pin tool to a P7 owner?

    A friend bought one at a gun show yesterday, but didn't know about the tools that should have come with it.
    And he didn't get them.

    Seems to me a bore brush would clean the gas cylinder, and a coin would remove the firing pin assembly just fine.

    What say you P7 owners??

    Top gun supply sells one as well

    It's expensive for what it is, but the gas port gets really dirty really fast. If he's going to shoot it much, it's a must. You can get away with a .270 bore brush once its scraped.

    Also, it's said that the after market scrapers are not good. I have no experience.

    The firing pin tool is unnessasary.

    The scraper and a bore brush are a must as I remember the gas port getting really dirty after firing just 100 rounds at the range.

    rc,

    The origial PSP did not come with a cylinder scraper. I did just fine without one for hundreds or perhaps a thousand rounds without problem.....

    Then one day, fortunately on the range goofing off, the slide stopped going back far enough to pick up the next cartridge. I used a worn out .30 cal bore brush and then a sloted wooden stick with a piece of the old lead out cloth through it on a hand drill, then another stick with a piece just shoved in under the tip of the stick.

    After that I took more effort to check and clean the cylinder and the piston.

    It was my favorite 9 silly meter. It was stolen and I can but hope the thugs sold it to some folks that eventually got it to a good guy that appreciates it.....or they paniced and threw it in the St. John's River and no thug has it.

    Mine had the odd magazine release, not the thin pull back or wide pull back but the German police thin lever one pinched forward. Liked it much better than the other European type releases. Never seen another like it in the US. The model was in use by Hessan dog handlers and under cover in 1981. I carried it in a BDU blouse waist pocket between two pieces of card board so it looked like a note book. It never got noticed, unlike my second favorite 9 silly meter a CZ75 in either an M7 chest holster or a 1911 swivel type "Cav" holster. I hated the 1912/1914 issue holster as it got caught in the seat of the old Mutt Jeeps on exit and just seemed n the way most of the time. The P7 was never in the way either in the pocket or in a little "bikini" belt slide under my BDU or Dress Greens. Handy little beast.

    Dispite my reputation as a .45ACP nut I never felt under armed with the P7 with a mag full +1 of CorBon's finest or the cheaper Silver Tips. The wife used the gun in Mas Ayoob's LFI 1 course and did well with it, except the one session she locked it in the car and had to use Mas' snubbie Python. The woman was spoiled I tell you......

    kBob, its mate is hanging in a very worn Jackass shoulder rig in my safe. Found it just after they were announced for U.S. sale. Serial number 9XXX. Small pinch release and all. It will be in my estate.

    Blackhawk44,

    So how is your health and have you named an executor yet? :D

    I almost bought one of the New Jersey police trade ins with the wide "Ruger Mark I" style of mag release but appearently eating and paying the mortgage was even more important to my wife than replacing the P7. It had been "her's" after that LFI1 class and she was distraught at it being stolen, but ended up choosing to replace it with a lower priced spread when she found out what they cost (mine was cheap having been imported on a Form 6A sans tax and tariff) and what a 2 1/2 inch python with a custom old style PPC trigger job cost.

    If you offered me one of anything HK ever built I would pick the clone of that missing PSP. Yep I know a PSG or a MP10 wouldbe cool and worth more bucks but I own guns to use and the PSP was flat usable.

    I've never brushed out the gas tube, I don't brush it out but I clean the tube with small patch after I shoot it, and my P7M8 works fine. I've been shooting it since 1985.

    I've only shot quality commercial ammo in it. The only foriegn ammo I've ever fired through it was Fiocci.

    Maybe if you fire dirty ammo through it the gas tube would need more attention.

    The manual recommends the scraper be used every 500 rounds. I use an aftermarket tool and it works just fine. Lots of crud comes out after hundreds of rounds. I'd advise your friend find one, HK or aftermarket. The aftermarket scraper I own is also a firing pin bushing removal tool. Two birds with one stone.

    There's little need to take the bushing apart though. A good cleaning every 1000 rounds or so should suffice.

    There is a ton of info online for the P7. It's a peculiar gun that is just different enough that owners need to know how to care for them correctly.

    Gunbroker has a couple scrapers and brushes for sale now. I didn't see a bushing tool. The old two prong type key, used on trigger locks, also works as a bushing tool.

    Yes, the scraper tool and the brush are both MUST HAVE items. Pay the money and get them.

    I just use the little brass scraper from an Otis accessory kit and a nylon .25 caliber bore brush, they work just fine at getting excess crud out of the piston area.

    RC am I to understand that there is something in the gun universe you are not an expert on? My world has been turned upside down!:uhoh:

    On a slightly more serious note, I am just beginning to run into problems with my P7 not locking back and sticking after almost 1,000 rounds through it. I am looking at getting the appropriate tools but I can and do get by with Hoppe's #9 and a cleaning brush for the piston itself. I will have to get a brush to get into the piston housing but there are many things besides the factory tools that will get this done. Hope this helps!

    RC, the regular brush has the tip with just the wire that the bristles are wound through, thus it does not clean the end of the chamber well at all. A dental pick might suffice, as might a drill bit with a flat edge; otherwise the scraper is the tool

    What I have used in a pinch is a tight-fitting patch soaked in solvent and a long metal dental tool. I push the soaked patch all the way in the piston area, let it sit, then use the tool to scrape a little bit as it snags the patch and pull it out. A blast from canned air helps afterwards

    RC, it is VERY necessary. You can never really get the gas port clean without it. Trust me on this one......

    Well see, I've been meaning to buy an HK squeeze-cocker for about 30 years and gain some personal experience.

    But they were always well out of my budget after the old Colt's, & S&W's, & Winchesters, & Brownings I had to have first.

    Now, I can't afford the extra HK P7 magazines I would have to have to feel secure with a 9mm!! :D

    I have one of the original P7s (what folks like to call the PSP) from when they were $400. Back then they cam in a cardboard box and only came with a brass brush for the gas cylinder (.25") and the striker assembly take-down tool.

    The brush kept the cylinder clean enough that when I bought an aftermarket scraper (from Cult of the P7) years later, there was hardly anything scraped out when I used it.

    A coin will not work for removal of the striker assembly. The rear of the striker needs to be brought back (with the squeeze cocker) flush with the rear surface of the collar, before the collar can be turned...it is like the magazine release of a 1911. However, if you bring the striker back flush, you can use your thumb to press down and turn the collar...the flesh of you thumb will fill the recesses and gain you purchase.

    The later M8 and M13 version did not use the take-down tool as the collar was extended out the rear of the slide.

    I think the magazines for the P7 have stabilized at about $50

    As a 3 P7 owner, I concur. You can easily clean it with a brush but the scraper does get a bit more.

    Avoid plated and lead bullets and you won't have many problems that a brush can't fix. Experience is a painful teacher sum days....

    What's wrong with plated bullets? I use them all the time with no problems.

    I use Rainier and Berry's plated bullets in my P7's and USP Tac also with no issues.

    As long as you don't shear the jacket from the plated bullets. There shouldn't be an issue. Lead is a big no no as it will make a mess of the gas piston system.

    Also I remember reading somewhere that 147gr bullets are too heavy for this gun.

    The P7 came on the market before the introduction of the 147gr slugs into the LE market...it was designed for a specific application for the military...and H&K issued a warning about using them in the P7 and the MP-5 due to the different recoil characteristics

    The scraper is chisel shaped. Haven't seen another tool like it.

    I've read a lot of opinions posted on forums concerning this matter but I've never seen a comment from HK regarding a warning about 147gr ammo. Can you reference this?

    FWIW; 147gr works fine in my P7.

    No, I can't. It was in the mid-80s, while the FBI were adopting the sub-sonic 147gr slug in response to the Miami Shootout.

    I was attending a departmental qualification class to qualify to carry a personally owned P7 as a duty gun. The Range Master teaching the class mentioned that H&K had sent around a notice (I'm assuming by snail mail) to give departments who used their products (We were using the MP-5) notice that they had encountered function issues with the sub-sonic 147gr slugs in their LE offerings (at the time that was the: 91, 93, MP-5, P7 M8/13). Their request was that users who encountered additional problems should bring it to the attention of the company. It was at the same time they warned us not to shoot Winchester Silvertips through the P7...that had been out departmental issued ammo.

    I didn't ask to see the notice, I just wanted to get through the class, get qualified and carry my pistol. I had no intention of carrying the 147gr bullets in my gun anyway

    I find the scraper to be absolutely essential. I can go an absolute maximum of 500 rounds without cleaning the cylinder, and prefer to do it after 250.

    I used an aftermarket scraper tool for a while, but it seemed to be made of a soft alloy because after awhile it definitely got loose in the cylinder. I finally sucked it up and bought a factory scraper and it got gunk out that the worn aftermarket scraper missed.

    The factory scraper appears to me to be made of harder stuff and shows no sign of wear yet.

    To get the cylinder really clean I'll use a combination of the scraper, the brush, and a patch, but the scraper is the most important.
