I saw on another site where a guy had his firing pin tip snap off after dry firing. I called Sig and they said they had only heard of 1 incident where this happened and it was not common. They have no plans to offer a revised firing pin and are handling broken ones on a case by case basis. They also will not sell firing pins or ship you the part to replace if it breaks. Hopefully if enough people call they can get some things changed.
I also sent an email to APEX gun parts and requested that they consider offering a heavy duty firing pin for the p365. Given the number of P365's that have sold, and the ones that are still backordered, I'd think the market would be excellent.
