You posted an interesting question. Researching Georgia's laws shows "concealed weapons" and lists several such as knives, bludgeons and firearms. It goes on to talk about carrying a concealed firearm which sounds singular. It's something I'm going to have to research deeper.
I have a GA permit, been stopped by LE while carrying primary and 2 BUG. I simply let the LEO know where they were at, kept my hands where they could see them and had no issues with them. The LEO was a little shocked at first, asking why I needed more than one gun. I then asked him if he carried a BUG. That seemed to satisfy his curiosity.
