Had a chance tonight to view a Colt Police Positive revolver and it left me with a question. Along the barrel where I normally look for the caliber/cartridge markings were the words ".32 POLICE CTR". I was expecting to see something like .32 S&W or .32 Spec. or .32 LONG. I've never seen the notation of .32 Police Ctr. Is there a special thing to know about this revolver or is it just a .32 S&W as I expected? Curious. Any info would be appreciated. Thanks, 725
