    How to lighten HK USP DA trigger pull?

    Does anyone know of a drop in replacement kit for a H&K USP 9 FS? Did some search but no success.

    Thanks!

    apparently put in an HK match trigger.

    Search over at Hkpro.com's forum.

    I'm still reading up on this.

      you can install a LEM or Match trigger- the LEM is DOA only I believe,
      neither are really drop in unless you know what you are doing. The best option is probably to send it to HK for the modifications. You can buy the kits from RTG parts in AZ or direct from HK.

      However if you want a "poor mans trigger job" you can always cut the hammer spring one and a half or two coils (no more or risk function issues) and that will lower the pull pressure very slightly. The only problem with doing this is the possibility of light primer strike with NATO ammo.

      oh - other option is send the pistol to Grey's Guns, they do USP trigger jobs.
      Seriously missing the 80's.....

            Check out Bill Springfield:



            People on HKPRO gave great reviews on his work. I haven't done my yet.

              Bill did my PTR91F trigger and its so much better after he adjusted the trigger pull. The PTR91F trigger is so bad that you would want it adjusted. Go with Bill. It only cost $55 and includes postage. It only took 1 week to get it back.

                +10 for Grayguns. Their work is awesome. Don't email Bruce, email Scott.
