Only retain mags if they have not been emptied. Do some IDPA , 3 gun and what ever they offer up @ Owl canyon. The 3 gun @ wcfw is open to all and you can go out, watch or participate. http://www.wcfw.org/3_gun/3_gun.html

You gotta walk from point A to point B with "x" amount of mags for the rest of your life.
Do you practice retain?? As mentioned, hypothetical SHTF.
