I was thinking of an M&P, but is it a DAO or is it like the xd and 99%cocked. With that said it seems it would be more vulnerable to a AD if it is like the xd. The way I understand it is that if a Glock's firing pin safety spring broke, there isn't enought spring pressure to ignite a primer. This doesn't seem to be the case with the m&p if it is 99%cocked.The xd has a grip safety to back up the firng pin safety.What i'm asking is that if the fiing pin safety spring on an m&p broke, would the gun go off? And if not what would stop it?
