Five SeveN Mk3 30 round mags?

Apologies if question is redundant as I joined the group just moments ago.

Is anyone aware of there existing reliable 30 round magazines for the Mk3 m? Research suggests to stay away from ProMag A2 version on the Mk3 due to reliability issues. Unfortunately I’m not aware of anything else existing on the market.

I have a 20 rounder that suits my needs, but figured having a 30 round capacity would be nice to experiment with for concealed carry.

Thanks in advance.
