If I carry my pistol under the auspices of SB-308, section 4-7, am I likely to end up in handcuffs?

Several states give military members ccw with proof of service. Missouri allows SM to obtain one at 18 while all others it's 21. Of course that is now. In January Missouri law will change to allow all law abiding US citizens to carry in the state. You can also apply for a lifetime ccw. Bare in mind that it's still nothe legal to carry in certain places and law enforcement to include retired are covered under LEOSA. But at the end of the day if your not flashing a gun or "accidently" revealing it why would a police officer need to make contact with you anyways

I am not a LEO working in Georgia but section SB 308, section 4-7 states persons in the military service of the state or of the United States are exempt of Code Sections 16-11-126 through 16-11-128 16-11-127.2 and shall not apply to or affect any of the following persons if such persons are employed in the offices listed below or when authorized by federal or state law, regulations, or order, which military member falls under. You need to read OCGA 16-11-126 to make you understand what the weapons code is saying. As an active duty military member this is what it says for active duty military members in OCGA 16-11-129: The judge of the probate court of each county shall, on application under oath, on payment of a fee of $30.00, and on investigation of applicant pursuant to subsections (b) and (d) of this Code section, issue a weapons carry license or renewal license valid for a period of five years to any person whose domicile is in that county or who is on active duty with the United States armed forces and who is not a domiciliary of this state but who either resides in that county or on a military reservation located in whole or in part in that county at the time of such application. In layman's terms, you will be issued a permit as a military member unless you are an actual Georgia state resident. Hopefully that has cleared up your question.

You must comply with the state law you travel through for CCW, I wish we truly had a national CCW standard.
