I have been wondeing about that ever since I saw the post on packing .org, but I haven't had time to research it.
I can tell you where to find the answer, though. Look at the Open Records Act, a collection of Georgia statutes that basically provides that all government records are open upon except what is listed as off limits. There, you will find your answer.
Found it: 50-18-72
(d) This article shall not be applicable to any application submitted to or any permanent records maintained by a judge of the probate court pursuant to Code Section 16-11-129, relating to licenses to carry pistols or revolvers, or pursuant to any other requirement for maintaining records relative to the possession of firearms. This subsection shall not preclude law enforcement agencies from obtaining records relating to licensing and possession of firearms as provided by law.
So, they are private except to a Law enforcement agency's specific request.
I just applied for my GFL on 18 April, and while in the probate office, I asked one of the girls working there if there were any public statistics on the number of licenses issued for Columbia county. She said no, but also went on to say the Augusta Chronicle had done an article on the number of licenses applied for / issued, which led me to believe the records were public. I suppose by agreeing to a NDS, the paper could get just numbers and not names to be published. I have not yet searched the paper's archived articles, as they want too much personal information to "join" their website, which I refuse to give. While on the subject, Columbia county scanned my prints, and the young lady I was dealing with said they would contact me within 30 days to come back and complete the 2nd part of the application. I'm wondering now, what else is left, especially after reading so many posts here about the process. The ladies at the probate office were very nice and polite. I was really amazed and expected a bunch of hassled old grouches to deal with!
