From what I understand pocket carry was illegal at some point in the past but this changed (I think in the 90s) by the addition of the words ",any other holster" to 16-11-126(c).
That language was not added in the 1990s.
Rather, here is what happened.
Prior to 1996, most law enforcement understood that a person in Georgia with a license could carry concealed. How else could one carry, for instance, in a purse or briefcase or other closed container? But AG Mike Bowers had other ideas. He declared in an AG opinion that one may not carry concealed but must carry openly with a license.
Governor Sonny Perdue, when he was a Senator, introduced SB 678, which added "in which event the weapon may be concealed by the person's clothing."
The news media immediately went into a frenzy (See Cynthia Tucker, Concealed Weapons: Putting Police at Risk to Please Lobbyists, Atlanta J. & Const., Mar. 20, 1996, at A16)*
, declaring that this bill would endanger law enforcement, which puzzled those of us in
law enforcement at the time who always assumed one could carry concealed with a license anyway and did not feel all that particularly endangered by people with firearms licenses in any event.
The bill also allowed a person with a license to carry a firearm anywhere in a vehicle.
The bill also added reciprocity to the Georgia law.
The bill also forces probate judges to issue licenses to active duty military residing but not domiciled in their county.
The act also did something about background checks for purchases requested by the GBI (adding a one day delay to what was previously instant) that I think has now changed, so I will not detail it.
According to Perdue, the NRA was heavily involved in pushing this bill and may have even initiated it.
Anyway, in sum, the words you indicate were not added then.
* And here we are 11 years later, without one single police officer having been endangered by this bill.
