Sig Sauer P365 Tac Pac No Safety; this model is NOT MA compliant (no safety).
I thought many guns have no manual safety including this one, except where required by law.
The 365 is also double action, as I stated.
I dislike striker fired pistols and don't own any. The consensus among P365 owners is that the striker is fully cocked by the slide action. That makes it single action to me. Others say it is only partially cocked, like a Glock, but that's still not double action in my mind.
Sig's website avoids the debate by describing the trigger action as "striker fired."
As for safeties, the only Sigs that I know have external safeties are the single action only models, including the 1911.
