Trigger Spring kit VP 9 Match
review-star review-star review-star review-star review-star
I have only had the gun since January but couldn't resist fine tuning the trigger. Original pull force was 5.66 lb. After the installation 4.06 lb. The video made the installation doable for me. I will say the locking block pin removal gave me the biggest headache. Some have stated they did the install without locking block removal. I never considered that. All in all great parts and great video. Thanks.

Question:
Is it safe to assume this kit with work with the VP9-B (Button) Models ?
January 4, 2026 6:45 AM
Answers
Yes — in most cases you can expect the HK VP9 / VP9SK / VP40 Trigger Spring Kit to work on VP9-B (Button) models, because the underlying trigger/sear geometry is the same as the rest of the VP9 family.

Question:
Hello Team, Would this work with the VP9 match?
October 1, 2025 1:02 PM
Answers
Yes - It should work - The trigger springs interact with the same sear/trigger geometry used across the VP9 family, so in most cases VP9 kits that fit the VP9 will also fit the Match. However, a few users and third-party vendors have noted small differences or mixed results when swapping “match/ultra-match” spring sets — particularly around trigger reset strength — so it’s worth being cautious.

The sear housing will not come out without removing the other internal parts first.

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.
