HKP +3 HK VP9/P30 Magazine Extension - Black

This was easy to fit to my 17rd magazine and works great with my low profile magazine well for my P30L

I've tried several mag extensions for different pistols and all seem to fall short in meeting expectations. Either they won't extend the capacity as much as they claim or they won't hold the chamber open on the last round. This one does it all well. I spoke with HK, told them what I needed and they made sure I matched the extension kit and spring size with the magazine I intended to extend. It works perfectly and you don't have to force the last round in the mag. I am completely satisfied.

Hi, I bought 4 of this mag extension, they fit perfe, the finish is perfect, they look very pro and bad ass. The research I did about this specific type of products shows that no need for different types of mag springs, nevertheless it came from factory with new springs. And that is a problem. They do not fit in the original followers the curvature is too wide and they pop out of the followers causing the followers to tilt and get trap inside the extension, Very frustrating

The VP9 +3 magazine extension looks and feels nice. It would be nice if the last round hold open worked with it though. I'm going to try a different spring to see if that fixes the problem.
