Good and bad - Tyrant CNC H&K VP9/VP40/P30, +5 Rounds Magazine Extension

Purchased for my VP9- GOOD: look and feel great. The finish is high quality and does extend the mag. BAD: not easy to instal (at least for me). The base plate did not fit inside the extender. I had to file down the base plate to get it to fit inside the extender properly. For me, it was easy, for someone else it could be a showstopper. My suggestion to the manufacturer: send a baseplate out that fits along with the spring. Easy fix. If you do this no one will have issues.
