Great Upgrade!

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.

Good price!

Haven't used yet but shipping was fast! Half the price of hk parts.net!


HK VP9 Trigger Kit

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.
Semper Fi.
