Hey... i dont trust the websites... i have a south carolina permit... planning on driving through georgia to ft myers florida.... spending time on sanibel and captiva island.     Are there any state or city issues i need to worry about?

GA and SC have reciprocity with regard to firearms licenses.

IF you have a SC license, you may carry openly or concealed, loaded or unloaded.

No duty to inform.
Cannot be stopped solely to determine if you have a license
You must have a weapons license to carry any knife with a blade exceeding 12 inches (recently changed from exceeding 5")
Georgia has state-level preemption, counties, cities, towns and villages may not regulate firearms except for discharge.

Don't carry into any -
(1) government buildings (as defined in GA Code)
(2) courthouses;
(3) jails and prisons;
(4) places of worship;
(5) state mental health facilities
(6) bars, without owner's permission
(7) nuclear power facilities,
(8) Within 150 feet of any polling place,
per OCGA 16-11-127

Probably don't need to add, but just in case ...
Use of Force in defense of self or others
Use of Force in defense of habitation (includes cars)
Defense of property Other Than habitation

Remember that you still have to deal with ANY differences in lethal force law between the states.

It is Completely up to you to understand any differences and comply with them

Bloomfield Press has multiple 'Gun Owner's Guide for XX [XX = state name]'

Reading them for ANY state you carry in is a good idea.

Differnt states handle lethal force in sometimes VERY differnet manner and the slightezt chamge in words can mean everything.

Virginia has NO statute law for lethal force.
It is ALL case law.
There is a lot of VERY GOOD case law.
Much of it from teh State Supremee Court.

There are all sorts of hidden traps though.
Are fists considered deadly force?
They are not in Virginia 'per se' but you can present evidence they are.

Is losing teeth a 'grave bodily injury'?

Not in Virginia.
Like many other legal issue the 'devil is on the details.'
