This place makes them for the P365 and Glock. They just came out with the one for the P365.I think it's something to keep an eye on, but I suspect it's also overblown. There are plenty of reports of Glock firing pins breaking too. I'll still carry one though. I'll also consider a steel replacement if anyone comes out with them.
