I have bought a 4 year old Surefire 9P-PH from a friend of mine today. He has only used 4 sets of batteries so far. It works fine with the P90 light assembly, but I noticed a dark spot in the center of the beam. Is it normal that the P90 has a shadow in the center of the beam ? Do I have to replace the light assembly ? Any help is very much appreciated.
