OP - S&W is top notch with their customer service. It’s a bUmmer your new to you gun has to there but it happens. Yesterday my wife’s 380 EZ Shield came back from service. It was there for just over 3 weeks. I sent it in for the safety recall and mentioned we had some live round stove pipes once in a while. Note sure why but it came back with a new barrel per the repair sheet. They took care of her and I am sure your used gun will come back like it’s new.
