My first two model 41's were older, pre 1990, and my last and current one is 2007 manufacture so I consider it of newer vintage. The 2007 model was bought used, but from a small shop that has a "return it if you aren't happy" policy. There is definitely a finish difference between older and newer model 41 pistols, but as long as they function ok, I can't tell much difference in shooting them. I have never had function issues with any of my 41 pistols, but with everything that I see today on the shooting forums, I wouldn't want to buy one without being able to handle it, and even then I would like to be able to shoot it first if I had the opportunity.
