The only thing cool about Savannah is the tree moss and St. Patricks.

I'm with QD. There is no con to having a CCW license. It doesn't mean that you are packing 24/7, eventhough many of us do. It just means that you've taken the time to be checked out and deserve to be able to use your own discretion as to when to carry and concealed.
I'll put it to you this way: Literally my entire family has CCW permits. No lie. My mom, dad, both brothers, my sister, my sister-in-law, my wife....everybody. Matter of fact I gave both my mom and my sister the gun's they carry with them everyday. We all feel that strongly about it. I'm also with QD in that noone knows unless we want them to. We don't walk around with bandoliers and shooting up in the air. Nobody needs to know until WE want them to know. I've had a bunch of people come up and give me a hug only to go...."ohhhh, nice" when they bump into something.....
My suggestion is to FIRST, take a defensive firearms license or at the very least get some real training and range time from someone that knows about firearms. When you're in fight or flight mode is not the time to start learning how to clear a jam or just how loud a gun shot inside is. You have to react instinctively. It's that simple. You have to know how to shoot with and without the benefit of sights. You have to be able to tell if a gun is loaded or not. You have to know when you can and can't pull your gun.
I guess what I'm trying to say is that it's great decision, but not as simple as going to the gun shop and buying a gun like it automatically will make you feel safer. There's some homework to do on your part. Many gun stores offer classes and some even specifically designed for beginners/women.
Once you're comfortable with that, THEN buy a gun that YOU feel comfortable with. Far too often people worry about caliber/size when what they should worry about is IF they can shoot the gun straight or not. You don't have to shoot an elephant gun to stop a threat. A well placed shot will go farther than anything else. If you're flinching from the expected kick or scared to shoot, it doesn't matter WHAT you carry....right? That's the point.
Anyway, hope this helps.
