What’s the best place to get them?
Cdnn, Top Gun Supply, MidwayUSA (when in stock). Check HKPRO vendors.
Also check G&R Tactical. They always seem to have good prices on HK mags.
Cross Creek Guns.
HkParts just got some in.
Thanks guys!
I would go with Grant at G&R. Better price and great service.
HK generally has better prices factory direct than most retailers. I ordered all of my P30/VP9 magazines directly from them.
When I called HK they had about the same price as Midway USA. G&R was less money, and HK Parts was a few dollars more.
I recently got some P2000 mags from Midway for about a dollar less each than HK direct. Would have gone with G&R but they were out of stock.
Looks like I’m going to stick with G&R.
I’ve had good experience with Midway. Most of the time they are on back order, but it does get filled within a few weeks. If you’re not in a rush you can just place an order and they’ll show up soon enough. Believe it or not Cheaper than Dirt had them at $36 a piece not that long ago; I’m not sure what they’re charging now, but even with a ridiculous shipping cost you can just buy in bulk.
Grant was out so I called up Cross Creek. Mike had 20 some available on Saturday. Mine shipped today so Mike is sitting at less than 20 now 
Mike is a great guy with good prices and fast shipping.
Who has them in stock is the real question. VP9 seems to have created an availability crunch.
In terms of dealer, I have done business with DSG Arms dozens of times and they’ve never let me down.
