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.
Not much return on investment.
As others have pointed out, this is one of the more challenging installations I have faced. Shipping and quality of product were excellent as always. Ran into difficulties with the install but have successfully placed both trigger return spring and sear spring into a functioning/tested handgun. Not as much change in break as I would have liked or have experienced from other M carbo products. A lot of my issue seems to be the gritty trigger take up that others mention on the vp9. The actual trigger break is lighter. The grit is absolutely not M carbo's fault though. Came to find out that if you are only doing the trigger return spring, you do not need to remove the frame block - IF you are careful when backing out the ambidextrous slide release on which the trigger returns spring centers.
Nice kit
This is my 3rd kit as I have this in my VP9Match my VP9L and Now in my EDC VP9. A great improvement over factory springs
fixed issue
I have a VP9 that I put the factory spring set in to reduce trigger pull. It worked great for a while and then it did not reset consistently. I have used M CARBO spring kits in other guns with great results so I ordered one for this one. Now the gun has a positive reset, with no noticeable increase in pull.
A Nicer Trigger In One Afternoon!
This was one of the more challenging trigger-improvement jobs I've done so far. The how-to video from Mcarbo is absolutely first rate - the clear instructions, the proper lighting and video angles, along with the discussion of how to overcome the difficult steps all but guarantee success.
Satisfied
Spring kit performed as advertised. Follow the detailed installation video and you’ll have no problems. Be careful not to accidentally loose any of the springs during the installation as you may find it difficult to find.
WOW!!! Not at all.
Was kind disappointed, trigger pull reduced only by Less than 1 lb. after replacing both springs. From 5.5 to 4.7. had problem with trigger return, called to customer support, was asked to send video and pictures, after no response 3 days later call again, was promised respond in 24 hr. ( Friday), still waiting, Monday. My Beretta 92 was much, much better improvement with springs replacement.
Fantasitic Product and Superb Installtion Video that helped a lot
VP9 has challenging fire control group to disassemble and reassemble for many people. However, the installation video was superbly nice and easy to follow. Just get the correct punches and tools, and it is an easy job.
Trigger pull dropped to 3.5-3.75 lbs

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?
December 10, 2022 5:45 PM
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
