I have a Police Positive Special and it's so marked on the left side of the barrel . It's in fantastic condition and I paid $400 for mine and was glad to get it . It's a fixed sight revolver but shoots very very accurately with my handloads , 3.5 grs of Bullseye using a 158 gr RN cast bullet . If you decide to buy it I would recommend having it disassembled , cleaned and oiled . I had that done to mine as I figured it hadn't been serviced since leaving the factory and it sure lightened up the action a bit and smoothed it . He charged me $50 , best money I have spend in a long time . If you buy it I wouldn't " hot rod it " , using 38-44 loads . Good luck , Regards Paul
