I there's been something about how in Fairy Tail there are no "REAL" guns. Like only magic guns. As in only magic bullets, and powered by magic and stuff. 
But I could be wrong. I don't think that would pose a real problem anyway though...

I do recall that Bisca used an actual gun in one of the filler episodes that showed her before she joined the guild. That's why I'm not really arguing about it or other related things that may or may not come at some point.
