HK USP & USP Tactical Match Trigger Conversion Kit

(2 customer reviews)


The HK USP Match Trigger Kit is a true drop in kit for USP full size pistols. This will fit all of the HK German USP 9mm, 40 & .45 Cal pistols. The Match Trigger Kit will adjust the trigger pull on single action (SA) to about 4 lbs. and the double action (DA) pull to roughly 7.5 lbs. All the while providing an overall smoother trigger with a better trigger reset. Each kit comes with all the parts need for the “match” conversion for your USP model and USP variants. A must have upgrade as this upgrade is a game changer.

Each HK German Match Kit Includes The Following:

  • Match hammer
  • Match hammer spring
  • Match trigger with over travel stop & tool
  • Match trigger return spring
  • Match nickel flat/sear spring
  • Match New style sear catch

Please note: Although the match kit is designed for the full size USP pistols only. The installation on your USP compact models can be achieved as the trigger will need to be slightly modified in order to be installed in your compact model if you want to use the match trigger in your USP compact models. Or you can use your existing USP compact trigger & not the trigger that comes with the Match kit. This ONLY applies to the USP Compact & NOT the full size. All of the other parts work & install the same way between the full size & compact models.

If you have a Pre-1995 model you will also need the new style control latch: HKPUSP9040

    Tactical Match trigger kit ( USP Pistol )

    F.Rab (verified owner)

    Order this replacement kit for my Usp 9mm ( full size ) decided against doing the swap myself. Took it to my smith ( old-timer with 40 years expirience. When I came to pick up the gun, he told me that this was not a drop in kit. Everything had to be handfitted. Took him 4 hrs to adjust everything. Now for improvements : double action pull came in 7.3lbs with a crisp break. Trigger does not stack and has a very consistent pull all the way through. Single has a slight take up breaks very smoothly. Reset is 50% shorter than stock trigger. I am sure it will get even better after break in. Definitely a must have for any Standard USP owner. Keep in mind that fitting might be required.

    Fantastic upgrade for my USP 45

    Bought the complete USP match trigger conversion kit and tools from and installed it myself at home in under an hour. The trigger pull is SO much smoother, pleasantly lighter, has a crisp break, and a shorter reset. And getting the trigger stop dialed in just right (with a little slack for reliability sake) the trigger feels simply amazing. I’d highly recommend this kit to anyone, and would say with basic tools and abilities, the right punches and the trigger return spring pliers (don’t think I could’ve installed the TRS with regular pliers) you ought to be able to install it at home yourself just as I did.
    After reading one of the reviews below I was hesitant to try but figured worst case scenario I could get it back together with the original parts and take it to a local gunsmith. But that wasn’t necessary, I had absolutely no problems with anything. I’m not even sure what parts would’ve needed fitting or how that could even be done. The only that was even remotely difficult was the TRS and with the pliers from I was able to get the spring in place and the pin back through it with only a little struggle. Nothing I’d shy away from doing again.
    Bottom line: totally worth it. And give it a try yourself, if it doesn’t work for you the way it did for me, take it to your local gunsmith. Either way it’s totally worth it for anyone who has a standard model USP
