I don’t know if the Sig P320 has a similar firing pin safety design to the P365, but I optioned to go with Springfield Hellcat vs P365 specifically because the Hellcat has two separate safety catch points on the firing pin assembly, thereby eliminating a single point of failure, while the P365 essentially has one (see photos here https://www.reddit.com/r/gunsmithing/comments/f7dgnl/how_saf...). Glock has also has a redundant “two-catch” internal safety design, and has a well established safety record (hellcat just worked better for my needs; glock was an equally good choice from a safety standpoint). It’s common in the US to carry in “ready” configuration (barrel loaded); IMO if you choose to do this, a single point of failure is unacceptable. It’s why hammer fire (with hammer disengaged requiring initial DA trigger pull to push hammer back) can be safer; you can also cover the hammer with thumb while drawing and feel if the trigger is accidentally engaging, helping to prevent a negligent discharge.

For anyone interested, here is a video showing Glock internal safety mechanisms: (https://m.youtube.com/watch?v=Fg2tlV1oqVM).
