spanks, if your carrying an extra mag or two that should be good enough. your carrying a glock so you know its going to be reliable. a total of 3 mags should be way more than enough god forbid you get yourself into a huge pickle. I haven't gotten into the habbit of carrying since I got my CCW, but I'd just carry the mag in the gun. I think 16+1 hollow point 9mm rounds would be enough.

or more like robo cop
