My glock 21 is hungry... Living in California has its limits as where you can buy ammo... there's the walmart/big 5 but I find they're getting expensive. walmart being $26 + tax per 100 of white box winchester and $18 + tax at big 5 for remmingtons at big 5.. so where do you guys buy? I'm not a gun nut yet, so reloading is not in the picture yet... anyone buy online before? gun shows?
