[Getting started] Does anyone know about Sig's internal safety mechanisms? Can't find ANY info about this online.

So we all know about Glock's fancy internal safety systems. No wonder so many people feel comfortable carrying them. Sig, on the other hand, has a manual safety on some of their P365 models although not on all of them. The question is, does Sig have some sort of internal safety mechanism to prevent unintended discharges? I am seriously considering a 365XL for carry, but it has no thumb safety which would go a long way towards my peace of mind as a new shooter. Can I be assured that even without an external safety this gun will NEVER go off without me pulling the trigger? Thank you. via /r/CCW https://ift.tt/30QJbee
