One extra mag but am going to start carrying a second spare mag. After watching these riots closely I can easily see situations where one mag just isn't enough. Example if you were in Rittenhouse's situation with only a handgun and one mag you likely wouldn't have survived. To pull off a similar feat you with a hand gun he would have needed more ammo. It's common now for a mob of people to surround a vehicle or surround a person on foot. World's a bit different today. Strongly suggest to anyone serious about self defense to work on your cardio as well. Ability to out run and escape your opponents is underrated in my opinion.
