I'm surprised I haven't heard anyone mention this on here yet....I use the coin pocket in my jeans for the extra mag for my LCP. It's free and works very well
When I carry my Ruger LCP, I keep it in my right pocket which is where the coin pocket usually is on my jeans so I'll usually carry an extra mag in my other pocket. When pocket carrying, I don't have anything else in my right pocket or coin pocket other than my LCP to make sure nothing gets in the way if I needed to draw.
