Whatever, Factory Boy, Lame things happen to firearms everday and its the factories that made it happen to begin with. Why send it in to have the same people that messed it up have a second chance to really mess it up?
Just polish the feed ramp and be done with it. You also may have a mag problem. Take the mag apart, spray the spring with some WD-40 let it sit for an hour and then wipe clean with a rag. Put the mag back together and load up. The two of these fixes are great. If you still have a problem, take the advise of "Factory Boy", Ruger_NUT, and call S&W to see what they say. CALL First.
