Pocket carriers, where do you keep your extra mag?

The title says it all. I alternate between pocket and AIWB (different guns) depending on what I'm wearing, but when I'm pocket carrying I don't know what to do with my extra mag. My pocket gun is a Kahr CM9, and I have a 6 round and 7 round mag with grip extension. via /r/CCW http://ift.tt/2mGj879
