Also, your ammo will be limited, make every shot count. Greenwolf70...hit it on the head. I have been carrying a spare mag for years, but a few months ago I started putting a pocket ammo holder in my rear pocket when I carry a small capacity firearm. Not a lot ,but 18 more rds might save my or the life of someone else. Just pray I would have the opportunity to load my mags for other shots if needed.
