How many magazines do you think are necessary per firearm? It seems like every time I buy a new gun, I'm spending a good chunk of money on more magazines, different ammo, optics, grips, accessories, etc. Of course it depends on the gun, I only have one spare mag for my Kel Tec P3AT, but 7 for my AR15. If you have more than one gun that fits the same magazine, then divide your magazines per gun. To narrow this down, we'll keep the poll to AR/AK/Fal etc.
