Front night sight halo fell off on a M&P9 while at the range 3 days ago. Emailed Smith & Wesson and 3 days later I receive a response requesting the firearm be returned for service for a turn-around-time of 6 to 8 weeks. This isn't a safe queen and I was planning to use it in a class mid-September. I've heard great things about S&W service turn-around of 2 to 3 weeks and now I'm not sure what to think. Is this the industry standard these days? What is Glock's recent turn-around time?
