Since open carry is NOT allowed in Florida and you do not yet have a permit (required in Fla for concealed carry), you will be breaking the law by carrying in public regardless of what kind of holster your pistol is in. The only exceptions would be some narrow loopholes that allow non-permit holding gun owners to carry unloaded weapons to and from gun ranges, competitions, etc.
