Hi Robinett,
Yes, just put the gun back into its plastic box and put that box into a cardboard box and send it back.
Over the years I have dealt with many real gentlemen in CS at S&W, and only one real jerk. In my experience, the odds of getting a helpful CS guy at S&W are far greater than with any other manufacturer or service provider that I deal with. (Just try to get a Kahr fixed!) Recently, I sent back my 20-year-old 640 no-dash with a frame problem and they are replacing it with a new gun. But it took some time for them to decide to do it and I didn't get any immediate satisfaction on any of my many phone calls.
I hope that they make it right for you.
Jeffrey
