Is the only option the P938 legion mags or do they fit other mags as well?

I see some P938 fit the Kimber micro 9 mags but I have not seen any confirmation about the legion. I am Leaning towards the legion over due the standard p938 due to trigger seems to be better.

Legion has the magwell and different baseplates for its 7-round mags. You can't put standard P938 7-round mags into a P938 Legion due to interference at the rear where the standard baseplates overhang the standard frame. Flush-fit 6-round mags work in either, but will be fiddly to seat in the Legion due to the magwell.
