Looking for some more expert opinions than me! My local Cabelas has a SW M&P 9 used for $100 less than new. It looks like it has hardly been used. SW says it left the factory in Oct. 2009. Am I better off getting a new M & P 9 or the used one? The main difference to me is time. The used one is there. I have to order the new one. The $100 I can save up if you think that is the better way to go.
