The installation video was very helpful - had a hard time getting the trigger pin to release but everything else went fine - trigger pull was reduced to a little under 4#'s so it was right where you said it should be - very happy with the whole process - definitely would recommend buying this kit & watching the install video...
Very Effective
Initially turned my vp9 trigger into mush, but later realized I had locking block issues. After polishing disco and trigger bar, the lower pwr mcarbo springs complimented the work. Sear and striker engagement still crispy after 1 year installation and use. Good stuff.
Great Set
Installed this on my optics ready VP9. As long as you follow the videos on you tube for installation, it is pretty simple until the very last step. Having the right plyers and patience the spring will go in. Took it to the range. Works great!
I have heard some people complain about the trigger reset being weak. I did not have any problems.
Lowers pull by 1 pound
Crisp
Definitely an unexpensive great upgrade. Pull from 5lbs 4ozs down to 3lbs 8ozs.
Weak spring corrected
I posted about a weak spring. My gun shop just called and said it is corrected, stating the cause was because he did not have it set right. Phew!
VP9sk Trigger
If you think your HK VP9sk Trigger is Awesome, wait until you do the Mcarbo trigger spring kit ! Now after have my gun Smith install the springs….. now it’s trigger to talk about!

VP9 Triger Spring Replacement
I'm certainly not an expert at this stuff but I wanted to lighten up the trigger pull on my VP9. This kit was very reasonable and seemed to have good results. The thing that sold it for me though was the video that showed how to do it. It was very detailed and gave me the confidence to tackle the job. It took me a couple of tries to get everything just right but I got it done. I don't have a trigger pull measuring device but I can really feel the difference. Definitely worth the money, time and effort.
Great kit
I got a vp40. Out of the box the trigger was gross. Every video I saw said trigger is good out of the box. Mine had a huge take up and heavy trigger. I got this kit and lazy wolf trigger. Had my gunsmith install this after seeing the video and knowing this gun is too advanced for me. Once I got it back gun was night and day different.
Does this work on a H & K P30SK?
Is it possible to remove just the sear housing without disassembly of the trigger block? Or does the block and trigger assembly need to be removed in order to remove the sear block?
The sear housing will not come out without removing the other internal parts first.

Can I assume that this will work on a VP9L?

Yes. I believe the only difference is slide and barrel length.
Can you use this spring package in conjunction with after market triggers such as the lazy wolf VP series?
Hello Jeffrey, we have only tested our springs with the factory trigger so unfortunately, we are able to confirm the functionality or compatibility with the lazy wolf VP series. Please let us know how it works out for you if you decide to test it out.

Does this kit help shorten the reset on the VP9?
October 29, 2021 12:44 PM
It does not. It will only lighten the trigger pull weight
