For firearms in general, see Florida State statutes Chapter 790.
Was reading a few articles on the Personal Defense Network website run by Mr. Rob Pincus and there was a good write up on the Clearwater, Florida shooting case occurring July 20th 2018 by a very good lawyer named Jon Gutmacher whose book I recommend in class. Here is a link, along with some related articles involving the legalities of self defense I encourage every one to examine if they are carrying concealed firearms.
