Yeah...so, I'm a bit overkill....
The reason I rock Glock 9mm is because I have a custom Kel Tec Sub 2000, with G17 grips that stays in the trunk. 9mm out of a carbine is serious business! So, I make sure that all my guns that I carry can be fed with G17 mags. No, I wont keep a G17 mag in my G26. I'll only have the loaded mag on me, and in my console are 33 rd "happy sticks." Does anybody need to carry that many guns and ammo around? Well, I can seriously piss off a large crowd because my mouth has no filter. So.......also, I believe in maintaining basic combat load of 210 rds at ALLLL times. Excessive, I know. But if zombies come I aint gonna be lookin stupid.
