You don't need HK branded mags. MKE and POF are more than fine. Either way, you want to have a ton of mags for your platform incase a ban or some other bullshit comes into play. The last thing you want to be doing at a range day is loading mags.

There was no difference between the MKE mag my AP5 came with, and the two HK mags I bought separately.
