Recently I bought a S&W model 10 from a pawn/gun shop and I am needing some identification help. The model number is 10-6. Serial number is D4341XX. It has the initials "D.P.D." stamped below the cylinder on the left side which leads me to believe that it was a police-issue in a former life. The revolver is a heavy barrel, fixed sight, wood square grip and is blued. It has holster wear but seems to be tight as a drum so it leads me to believe that it spent a lot of time in it's holster which I do not have. Any assistance would be appreciated. Thanks!
