I was just curious on how many magazines do you owners own with your glocks? For range purposes and for home defense purpose. I'm going to order the extra magazines when I order my Glock 21 here next month and was curious how many magazines is too many magazines? Unfortunately I live in Illinois (yea Illinois gun laws are not the greatest) so I'm not to concern with how many magazines for conceal carry (right now at least) but if you want to give your in put on how many you have when you conceal carry, please chime in. Thanks in advance for your input!
