EXCELLENT trigger upgrade from MCARBO!!!

These are excellent upgrade parts for a VP9 - the video describing how to install was awesome too. Made it almost easy to do. I had a solid 2lb trigger pull drop. Fast shipping. Excellent all the way around!!!


Awesome Shooting upgrade!

Unbelievable difference in trigger feel and break! Coupled with the Lazy Wolf Flat trigger I went from liking my VP9 to LOVING it! The install video and the in-depth coverage done By M-Carbo made it a fairly easy project to tackle myself as well. Couldn't be happier!

Excellent product and installation video. I’m looking forward to trying my upgraded H&K VP9 on the range this week. I will be upgrading my son’s Glock 43 next and expect the same excellence in springs and video. MCARBO does excellent work.

HK VP9 Trigger Spring 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.
