How do I transfer my pistol from my state of residence to the state I go to college?

It's not "concealed" if it's in a locked case, properly inspected at the time you boarded, no ammo, and not accessible. Keep it locked in it's case in the truck of your car until you get home. If you get pulled over by LE, tell them you have it. Transporting firearms and carrying concealed are different matters. You might also want to check up on Florida's rules regarding transporting firearms before you get there.
