I think we girls are much more limited to what we can carry than the guys. Our clothes don't allow for much, and while people are used to seeing "bulges" on guys, I don't think it's so much for girls - at least nobody's used to seeing any bulges on me LOL! Just think about the jeans most girls wear, and the thinner tops and more revealing stuff - I'm not a slutty dresser, but anything I can carry would have to be really, really small.
Do girls usually carry their guns in their bags? I could bring a gun that way, but I wouldn't feel the most secure having it there. It takes me 5 minutes to find my lipstick in my bag!
