I was lucky enough to pick up the last G23 magazine my local dealer had. I want it in my G27 when it's on my night stand or in my vehicle. I`ll use the standard magazine with the 13 rounder as a back up when I`m on foot. What is the best way to extend the life of this now rare high capacity magaine? How much extra wear if any will I cause if I keep this magazine loaded? How often should I fire it off my carry ammunition? Any suggestions are welcome. I`m new to this. My TN carry permit is processing as we speak. Thank you!
