Heckler & Koch USP Match Trigger Kit
Factory OEM match trigger kit that fits HK USP full-size 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.

First, Rooftop Defense is great to work with. Excellent price for this kit, and very fast shipping.
As a bit of a trigger snob and HK “fanboy” I have to be honest. The USP match trigger kit is an improvement over the stock standard USP trigger. The hammer has a more polished contact surface where it rotates against the sear and the sear ledge on the hammer is fully deburred. The overtravel stop on the trigger shoe does help to reduce reset travel. Having said that, it does not radically change the firing mechanism. The reduced action pull is mostly achieved with a significantly reduced power trigger return spring and a reduced power hammer spring. I’ve used the reduced hammer spring in my P30 with no light primer issues, so that isn’t a problem. The trigger return spring on the other hand is very weak and during my installation with the correct pliers it deformed and became unusable as it would no longer return the trigger without “help”. That’s my reason for four stars. It’s HK parts and except the TRS very high quality. Just know what you’re getting yourself into and don’t expect a radically different trigger without some serious deburring and polishing on all contact zones and pivot points within the mechanism.

This trigger kit is great! Sol is an awesome guy and he shipped my order the same day (one of the few shops that had this kit in stock). I will support Rooftop in the future and look here first if I need something. Thank you, Sol!

This kit was exactly as described, brand new in HK packaging. Not my first foray into HK trigger work, I found it easy to install. Double action is smooth, no stacking and single action is light and crisp. Rooftop shipped this crazy fast, and also hooked it up with some ramen and a sweet rooftop defense slap! Very responsive and even responded to one of my posts online about the kit. Great customer service, and they’ve gained a customer from here on out!

I have ordered this trigger kit 3 times from other vendors and they were never able to deliver. Rooftop had it in stock and shipped faster than the estimated time plus they sent some ramen for me to power through. They have become #1 on my list for parts and supplies.
