    New h&k USp 9mm... +p and+ p+ rounds ok?

    So I just got my first carry gun. Always been a shotgun fan. The law of ca-chook did tame the west after all. I digress.

    It's an h&k USP 9mm stainless...

    Having little experience with handguns, I want to ask upon the breath of knowledge on this forum.

    Can this gun handle +p and +p+ loads? I mean it is German and Germans build GOOD stuff!

    Follow up guesstion: what is the best or shall I say cheapest training / target round options?

    both the +P and +P+ will work in the HK USP BUT.. The manual does say that +P and +P+ will accelerate the wear and reduce service life. So the way most of us go is we use +P very limited at the range maybe 5 or so rounds
    but most are fine with daily carry
    for more info on the +P+ load you might want to ask over at hkpro.com

    Good luck and enjoy you have a great gun there

    1shooter, I also have a USPf 9mm. They say HK is the only manufacturer who specifically says their guns are +p+ capable. I have not read every manufacturer's warranty, but my HK warranty, unlike my S&W or Kahr warranty does specifically note that +p+ is ok, but as Craiger notes above, either +p or +p+ will accelerate wear.

    I probably have about 3000 rounds through my USP, with no discernable wear. Every couple of times I go to the range I shoot a mag of Winchester Ranger 127 gr +p+ since it is my preferred SD round for that gun. All the rest of my practice is with whatever 9mm FMJ is available. When it is available, I prefer Winchester White Box from Walmart, but the HK will gobble up anything including the less expensive Wolf/Tula Russian steel cased ammo that I sometimes buy online.

    That's really, really, really, really, really.... conservative. Well made modern firearms can handle thousands of +P rounds. I've put at least 5,000 rounds of +P and NATO pressure ammo through my EDC Glock 19 with zero signs of accelerated wear. In fact, the gun still looks brand new with a full clean.

    I wouldn't, however, make a habit of shooting lots of +P+ rounds.

    Bear in mind that these pistols are designed to shoot the European CIP-spec ammo that runs hotter than most of SAMMI's +P loads...as well as CIP spec 9mm NATO that runs hotter than +P+.

    In short, it'll handle it just fine.

    Hmm, are you sure about the European 9mm NATO having higher pressures than +P+? I've shot tons of 124 gr. NATO ammo manufactured in Europe, and I've never had any round chrono faster than the Winchester 127 gr. +P+.

    AZ Hawk, you are correct, in fact NATO spec ammo is not as hot pressure wise as +P. Here are the actual numbers:

    SAAMI max pressure for standard 9mm Luger is 35,000 psi
    NATO spec max pressure for 9mm Luger is 36,550 psi
    SAAMI max pressure for 9mm Luger +P is 38,500 psi
    There is no SAAMI or other standard specification for 9mm Luger +P+, but presumably it's above 38,500 psi

    Use the two types of ammo for SD only and not range ammo. Do that, and you should be fine.
    Glock: G22 .40 S&W and G23 .40 S&W Sig Sauer: P938 9mm Smith and Wesson: Model 437 .38 Spl, Model 65 357 Mag, and Sigma SW9VE 9mm

    I know HK tested their P30 9mm for 365 days, 133 range trips, 513 hours, 15 types of ammo (+P+ included) and it only lasted 91,622 rounds!

    I sure you won't wear out your USP if you put a couple 1,000 rounds of +P+ through it! Good weapon! Enjoy the great purchase.
