So do I need to reapply for a CCW if I move to a new county?

NO you keep the same permit but tape a change of addy on it. The best way to maintain legality is,.............................Call the sheriffs dept of the county you will be moving to. Most web sites for each county have this info on the site.
REMEMBER do not discuss NFA items with anyone from any dept at all. Unless you feel chatty and need a new BFF
