| I have a brand-new USP Compact in 9mm. I took it to the range tonight and it jammed 4 times in 50 rounds that I put through it. I admit, I did not clean it prior to firing it. I inspected it and it was clean and lubricated; as you would expect with a new-in-the-box HK. I was really surprised; any thoughts? |

Yeh, normally I would have cleaned it first; I guess I was a little eager to try out my first HK. I found a thread on another board where the poster had a nearly identical experience. I certainly wasn't limp-wristing it when it jammed; although one time was during a rapid 2 shots where I may have been limp for the 2nd shot.

I inspected it and it was clean and lubricated; as you would expect with a new-in-the-box HK. I was really surprised; any thoughts? First of all you pistol was not clean and lubricated. The stuff HK puts on them is a preservative. It is thick and sticky and is not meant to lubricate but to preserve. That is your first problem. Second, the USP and USPC were built as .40 calibers first, then lightened to shoot the 9mm; opposite the way other companies did it. So, when shooting the 9mm you will find that it is absolutely essential to keep a very firm grip and locked wrist. Recoil is so light that it is easy to relax and roll with it, but that is the surest way to induce a jam. Now, clean your pistol like you had just shot 500 rounds through it and get all that brown thick crap out of there. Lube it like the manual tells you to, keep your wrist locked and a firm grip and you will not have any more jams. ed: sorry for repeating what everyone else told you. I see this exact same thing so many times at HKPRO that I just answered without doing any reading of the previous replies. At least you know we are not pulling your leg. |

Your one helluva resource buddy and I appreciate it a ton....I did not know that the usp series was built w. the .40 org. That is a cool tidbit.

| What a coincidence. A couple weeks ago, I just fired my NIB USP9c with the same Rem. UMC 9mm 115gr. 250rd box. I had 2 FTE in the first mag and then one more maybe 50 rounds later. I then field stripped and cleaned the pistol. Went back to the range the next day and fired about 200 WWB and had no issues whatsoever. Another interesting observation with the UMC ammo (although maybe un-related), was that many of the bullets appeared to be seated much deeper in the case than normal and the consistency among cartridges seemed to be very poor. |

This is just like people bitching about 4th Gen Glocks having stoppages with shit ammo. The recoil spring is made for real ammo, so using cheap light-loaded shit may induce stoppages, ESPECIALLY in NEW weapons.
So please, go put more rounds through your weapon (1k at least) and then decide on reliability. And, as a side note, if you aren't a SEAL or operator or soldier or sailor or airman or Marine or whatever, please don't make screen names that refer to yourself as one (my apologies if you are a SEAL). |

UMC is the devil and you occasionally get one that will blow up your gun. I bought 500 rounds of 40 and two were completely dangerously seated and another I wasn't going to risk it. It's a combo of the bad way they pack it and not enough tension around the bullet. |

Six years ago, when I signed up on ARFCOM, I owned a company named CyberSEALS. It was an application hosting provider for game servers. We hosted servers for Microsoft when Halo was launched for PC; hosted for America's Army (developed by the US Army) and other fun stuff. I sent a request to change the screenname years ago knowing it could be problematic here and it was never fufilled. I've never uttered anything here, or elsewhere, that would make someone think I'm something I'm not. As a side note, I offered one of my domains, cyberseals.net, to the cyberseals.org folks...check em out. |
