It is a 25-2. It isn't stamped with the typical "N" on the back of the cylinder, but is stamped with an "N" under the grip area. It appears to be factory nickel, as it is on par with my other nickel smiths. I had never seen one in person, either, so I jumped at the chance to get it. This is prolly one I need to letter to be sure.I have to ask. Is that a factory nickel plated M25-2? The reason I ask, is that I saw them listed in the S&W catalogs, but never saw a real one.
