The FEO coming to see you is just part of the process and although he was may be satisfied with your interview he would not have granted you a FAC. Your application, his/her report along with your referee forms (which should go straight from the referee to the Firearms Licensing Dept will all be submitted for consideration/ checks on you, your referees and your land. Some forces it is the Officer in charge of the Licensing Dept who issues FACs on behalf of the Chief Constable some it is actually the CC who signs them. Depends on how quickly your force processes applications but with some I would not hold your breath.
