Older USPs

    Henry's Dad woof, woof

    Have USPs gone through "gen" upgrades (or downgrades, depending on your point of view:whistling:) the way Glock has?

    Any parts compatability issues between USPs from the '90s and ones made today?

    Any issues with used USPs in general that a buyer should be aware of? Were there "bad" years or a bad string of years?

    The only thing I'm aware of was the firing pin problem in the USP Compacts that were built before 2004.

    Other than that, I don't think much else has changed. Reliability and durability wise, the USP is at least twice the gun that the Glocks are and have ever been.

    The early Compact 9mm and .40 cal had some horrible triggers - gritty and heavy. It was improved with the later issue .45 USP Compact. A good polishing of the trigger system in the early models would improve the action.

    Secondly, on 2001 Ayoob pointed out that there were some failures to fire using 9mm Winchester White Box in the 9mm USP Compact. Apparently some lubricant got into the firing pin channel which would not allow enough force to light up the Winchester standard pressure round. It only happened occasionally, not all the time. Maybe it has been fixed by now.

    I love wild gun claims :whistling:

    I love my USPC9 and USP45... never thought they were significantly better than my Glocks though. All I know is that I can't shoot the 45 nearly as well as my G19 :rofl:

  12. :rofl::rofl::rofl:
    Oh, c'mon! Twice the gun? GTFO. I own both and they are both excellent. Enough said.
  13. The USP .45 Compact has a lousy double action trigger, too. It improves somewhat with use, but it's nothing to write home about.

    I forgot to mention that the early USP's had a HK specific light rail. Only HK lights would attach to the pistol. Later they changed the light rail design to accept the more commonly available lights made by other manufacturers.

    Thought the USPs still had that HK rail. I have a USP .45, not too old judging by the later hangrips, and I had to get a GG&G mount for it.

    I'm working off of memory here so you may be right.

    I used to collect magazine articles about the USP and thought I saw a rail change mentioned in one of them. I no longer have those articles.

    My personal USP dates back to 1998 and I know the series underwent some changes since then.

    Regardless, it is a very robust and reliable firearm. I can only remember 1 failure to feed from a magazine with a tired spring.

    I really cannot complain about the USP.
  17. Slobo

    Me neither. My USP .45 is one of my favorites. Shoots like a dream, very robust and no issues.

    p.s. the GG&G rail convertor adds virtully no weight so leaving it on is no issue.
  18. I purchased a usp in 9mm when they first became available. It was well made but not accurate. I sold it soon after HK changed the barrel rifling on newer pistols. I would avoid those early guns.
  19. I had to replace my sear spring, but supposely the earlier USP compacts (mine is a 2006 model) this was an issue.

    I will tell you that HK took care of it at no charge!! I just paid the shipping to HK from my LGS.
  20. When did the lock come into play? Would rather find a pre lock model.
  21. I have an AC(02) model .45. Where is the best place to get replacement mag springs?
