And to the guys who don't see the need for spares. Damn y'all are good! I'm impressed. Hope you don't take offense if I carry a couple of spares since maybe I'm not a pro like y'all.
Has nothing to do with being a "pro". In my experience, I have found that extra mags are just not needed. Keep the mag in your daily carry clean and in good working order and you will have 0 problems. I am not in law enforcement so I dont run into bad guys daily, but if I do, I am 100% confident in the weapon/mag/ammo I carry.
