Florida law regarding car carry.

This question came to mind after a recent shooting at a local gas station no more then 300 yards away from my school. Lets say you were legally carrying a firearm in your vehicle but did NOT have a ccw. In florida you can defend someone else as if it was you(or something like that). So lets say you have a loved one inside the store and you hear gunshots, you run outside and get in your car only to realize that your loved one wasnt able to make it out. Could you legally retrieve your firearm from your vehicle and return to the store to try and get your loved one out unharmed? This isnt a moral question of "Well even if it was agaisnt the law I would..." this is just pure yes or no is it legal. Thanks for any time or research put into answering my question because my research hasnt lead me to a conclusion.

Commonsense was telling me that id be illegal as soon as you stepped out of the car. Anyone know if there is a law that allows this certain scenario to happen? Maybe something that states certain times you're allowed to break the CCW rules like when you bring your firearm to and from your car going to the range etc. ty for the quick response

Darn... I guess we failed at trying to find one of those "loopholes" people are always talking about
