In a nutshell? Very positive. The mag body seems like it was made to fit the VP9. And the follower fits inside the mag body perfectly. And has yet to fail locking back the slide on dry fire.
Not even once.
Is this definitive? No, of course not! It’s all relative. But up to now, aftermarket HK Vp9 / P30 magazines have been dumpster fires.
This one shows great promise. Even in dry-fire! Which is indicative of just how low the bar is for aftermarket HK mags.
