He may be refering to the fact Georgia required an actual Holster for CC or OC. But not sure if there is some kind of law that allows it in Ga.
a holster is only required to conceal open carry requires no holster in GA...
also a hip grip can be used id consider the clip a hip grip(it isnt defined neither is holster)
