Bear in mind that sometimes a firearm may be pushed to the front for what S&W considers an emergency when it comes to service/repair. This sort of thing is described in the back of the safety & instruction manual ...
"In the event of an emergency (repairs needed by law enforcement, an upcoming match or hunting trip), call 1-800-331-0852, ext. 2905 and ask for 911 Priority Repair Service. This allows you to speak with a Smith & Wesson representative. Immediately upon receipt, your firearm will be assigned to a gunsmith."
