Do not be surprised if the only communication you receive from S&W is a letter accompanying either your repaired rifle or a new Sport II.

You do need to understand that while you have so far only expressed an interest in getting the gun repaired, in the eyes of S&W's attorneys you are a lawsuit waiting to be filed, so the communications may become very formal - and sparse - from this point on. They will fix or replace your rifle, but that may be about all you ever find out about what they learn about what happened.
