H&K HK USP/USP Tactical Match Trigger Conversion Kit

This is a game changer for my HK ÚSP 40. This instantly made a huge difference in the overall performance of the gun and my accuracy with it is so much better. The trigger is so smooth and crisp now. I love it!!! I did it myself and it took me about two hours. It?s not hard, but I have never taken my USP 40 apart like this. Just take your time and you can do it.

Easy to install with right tools. Noticed a difference in trigger pull.

I purchased this part for my HK USP Compact.45 and it works perfectly. Aside from the trigger itself not working I was able to get pretty much everything else working. It still fires perfect and it dropped my double action pull approximately four pounds. It is definitely an upgrade that I would recommend installing.

This is a great upgrade. The single action pull on my USP .45 is light and crisp now and the double action pull is lighter and smoother. Definitely worth it. And as this was my first time to detail strip my USP, I was extremely pleased with how well designed the pistol was. 10/10 would recommend.

I wish that I had bought one sooner it shortend up the pull in double action and has a smooth break everytime, I never would shoot it in double action before and single action is a short light pull with a reset you can feel. I installed it on my USP9C the only thing that doesnt fit is the match trigger but it doesnt change the performance in anyway keeping the stock trigger when it breaks the trigger is pretty much touching the frame your not wasting and travel on your pull. It's my favorite gun to bring to the range now, Great work guys Thank you.

I ordered the match trigger replacement kit and installed it in about an hours time. Just take your time and pay attention to what your doing and be patient. It took me a few times installing the spring for the trigger though. Other then that all the parts fitted correctly. The trigger has a much more smoother break and a much better reset when pulling the trigger now.

Two a two-year wait got the kit , it does drop the double action to a much better wt, the Youtube vid was of little help as he did too much off-screen and had his hands in the way the rest of the time, I use the parts break page from the owners manual to put it back together

Bought the complete USP match trigger conversion kit and tools from HKParts.net 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 HKParts.net 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

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.
