I don't carry an extra mag with my LCP much either. If I do, it's in a nylon multi tool sheath that fits the mag perfectly. I'm not worried about that showing. It simply looks like a simple multi-tool on my belt.
If you like the Clinger, check out Remora too. They are about half the price and often on sale. I seem to get a free one when I get a holster from them, but don't carry an extra mag that often. Mostly use them for mag storage in my range bag.I looked at the Clinger Mag Pouch and liked it! No flaps or Velcro to hinder access to the mag. Just what I was looking for. Thanks!
