Those are valid points, I'd design a hard target or use what security experts & law enforcement call CP-TED(Cep-Ted) or crime prevention thru environmental design. Smash & grab plans and take-down style armed robberies are more common. Crooks steal a vehicle than ram it into a gun shop or range.
Reig's a training center, gun range and FFL holder/shop had a armed robbery where a armed mgr shot 3 violent thugs then about 2mo later the same location had a smash in theft late at night. This shop was in metro Orlando FL.

ps: there are a few Florida based shooting sports firms;
www.serbu.com www.magsafeonline.com Knight's Armament Corp(KAC).
I'd offer a 10% discount too for veterans, first responders, corrections, and maybe valid NRA members.
