With a little luck, I will be in the market for a revolver next month. I have decided on the Ruger SP101. I was looking on Gun Broker and there was a seller with a 2013 model for almost $1000. His explanation was that the 2013 models were hard to find and that there were improvements made in the new model superior to the older models. Is this true (and if so, what improvements were made) or is this guy just blowing smoke and trying to get $1000 for a Ruger revolver?
