Hi , I just Bought my first Revolver. I bought a .38 Spl, I've only shot Pistols, shotguns and rifles before. I bought the Taurus on the recommendation of the dealer I buy from, who has sold me countless firearms over the years. I do have a question, I bought a M85UL 2 1/2 ss. I can figure out the 2 1/2 is the barrel length. I found the serial number on the box. IThe box also has a 2-850039UL on the box. Is this the Model number? I want to fill ou my registration card and send it in. I looked on Taurus's website and in the owners manual, but couldn't find anything. Any help would be appreciated!!!!
