Very easy to install. Lighter trigger pull. Love it!!!!!!
Not my first rodeo doing various trigger upgrades and I have a selection of gunsmithing tools but I cannot get the nub block pin to move on my VP9SK. I have installed the trigger spring only at this time. I would love a video on just the nub pin removal on a gun that had not been disassembled repeatedly. This is the bitch point in this upgrade.
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.
I have done 2 VP9's with this kit. They both went well and the results are AWESOME. Keep up the great work guys. Products like this make a difference!
Followed the video and got it done pretty quick. Love the way it shots now.
The Vp9sk has a great trigger to begin with but after I married this spring kit to my Vp9sk it greatly improved the feel and It was easy to install, about 20 min job. Very pleased
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
This inexpensive spring kit for the HK VP9 reduced the trigger pull about 1 lb. from stock.
However, be advised that installing the parts into the HK VP9 is not for the faint of heart. MCARBO has a very good installation video and I recommend watching it several times before proceeding. In addition to basic tools needed for gunsmithing, you must have a set of roll pin punches and a needle nose plyer.
There are two small springs you'll need to watch out for because they're easy to lose: the Disassembly Safety Spring on the locking block and the Slide Release Spring. I've worked on several VP9s so I'm quite familiar with the internals and the installation did not take long.
Received this kit in the mail about 2 hrs ago, followed the install video and was done in about an hour.
The install was easy and the trigger feels great, couldn't have done it without the excellent video.
Make sure you have the recommended tools before you start. Be very careful with the small springs.
Purchased the HK VP9 Trigger Kit. Installation of Trigger kit was accomplished while viewing the MCARBO video. Two different procedures pushed my patiences first is at 9:51 on installation video removing pin that holds locking block located above trigger spring. The second is at 36:48 on installation video internal safety located on locking block.
Chris is correct when he states pin might be difficult on a new weapon. I would like to thank Jake with MCARBO technical department. Jake talked me off the ledge in regards to removing the pin, I was frustrated and about to get my drill to remove pin. Jake had me take a deep breathe and said that Chris does make removal of the pin look simple. With Jake’s advice I was able to remove the pin.
Returned from the range this morning and could feel a difference. I am happy with the results and MCARBO’s trigger kit.
Didn't think it would make as much of a difference as it did but after having installed other trigger kits from MCarbo, my expectations were definitely met.
Install seemed intimidating at first but after watching the detailed install video, it was easy to do.
I would suggest test fitting the 1/8" punch, I had to sand the diameter of my punch a little to fit without enlarging the pin hole. The tape on the end of the needle nose tips was great, the spring popped right in on the 1st try.
Trigger weight for my VP9SK was reduced from 5.5# to 3.5#.
* Great price
* Works well
* A very detailed and helpful install video
* Fast processing and shipping
The stock trigger pull on my VP9, was between 5 1/2 to 6 lbs. I had previously installed the ultra match trigger kit from HK parts, and it dropped the pull weight to 5lbs. Unfortunately, the trigger failed to reset about 10% percent of the time. I found this to be totally unacceptable. I installed the Mcarbo kit and am very happy with it. The trigger pull is a consistent 4.25 lbs, and has been 100$ reliable. It is also smoother, with less grit. I could not be more pleased with it! Now, I am just hoping Mcarbo comes out with a flat trigger for the VP9. Well done!
Outstanding installation video! I also watched it completely through then used it again going through the entire disassembly assembly process.
One thing my VP9 is doing and it may be because its so new with less than 700 rounds through it. Is when locking back the slide prior to removal and rotating the disassembly lever down the trigger isn't moving completely forward. Its just a couple MM short. I tick it forward the rest of the way and the slid comes off without hanging up.
So I thought I had missed or done something wrong and took the locking block out and did a fresh assembly with the same results. Then put back in the factory spring and the trigger moves all the way forward when rotating the disassembly lever down. Then back in went the lighter spring and I was back to where I ended up the first time. So I concluded I didn't damage anything and its not a lubrication issue. Its just a byproduct of a lighter spring. Which is ok when I fully (Im sure I do but who knows maybe not) understand whats going on. It may self correct with time and parts wear in?
Another trick I figured is once the dismounting safety is on the locking block. I could hold the safety clamp/dismounting safety in place with my long needle nose pliers when installing the locking block. You see I suffer from SFS (sausage finger syndrome, sad but true my whole life) Then pop the right slide release in, up to where it just shows in the locking block and that will hold that little !@&*#@ fiddly assembly together along with the disconnector. While I loosely put the front locking block pin in and then the spring.
Hope this all helps?
I had a previous poor rating for the spring set, but after talking to a service representative, it made have been a QC issue with the set or that my VP9 has a low round count. They made things right and got another set to me resolving my issue. Great customer service, can't wait to fire my VP9!
