I bought several for my P30 but haven’t made it to the range. Anyone tested theirs out? I assume being a factory HK mag, it should be GTG but thought I’d check.

i have several along with the factory 20rd mags. they have all run perfect for me. i haven't beat the crap out of them, but they have given me zero problems.

Same as Dozer. Have three that came with a recent acquisition and all seem to function fine.

bought three when they came out and ran a few boxes of ammo through them. No issues.

I don't know how many they are OK notes you want. I bought way.way more than 3. they run fine so far. With covid my shooting schedule is reduced so I can't say a zillion rounds, but no issues and I wouldn't expect any given the nature of the change HK made.

I have not read or heard a single complaint.

I have never had a problem with any factory HK part.

Have a few. No issues in my VP9. They seem to eject with a bit more oomph than the 15rd versions.

Only HK part I've ever had issue with was the paddle mag release on my P30L. It was manufactured a bit off so the mag wasn't held up into the grip as far as it should. Minor issue, didn't affect the functionality, but I noticed it, and noticed the "good" part HK sent as a replacement was indeed dimensionally different.

That instance, though, showed me that HK's customer service was actually excellent. I've had to deal with both HK and Ruger customer service, and both sold me on the companies as both were excellent.

Only have the 20rd mags; no issues with those. Doubt that I'll ever pick up any of the 17rd examples; neither my P30 or VP9 will ever see serious use as a carry.

been using 3 HK 17-rounders for months, VP9, no issues at all. I shoot once per week, at least 100 rounds. Probably have put over 1,000 rounds through the 3 mags.
