There is no manual safety. There is a trigger safety, and firing pin block. Depending on where you live, there may be a magazine safety.

The trigger safety prevents the gun from firing if it gets caught in the perfect way so that only the top half of the trigger is pulled. It is not much of a safety and won't prevent discharges if the gun is kept in a pocket with other stuff or in a bag unholstered.

The striker block prevents the gun from discharging in the event it is dropped. The SD's also have a little more safety margin than the M&P's because the trigger pull also finishes the cocking of the striker whereas the striker is fully cocked with the M&P line and only the sear is holding the striker back (along with the striker block if the trigger isn't pulled).

Of course nothing will beat the safety or lack thereof between the ears.

The way I understand it, the trigger safety is a "drop safety" and not a "get it caught in clothing" safety. The trigger safety is to keep the trigger from moving rearward under enough momentum during a drop. For instance, if the gun is dropped on the grip end from a good distance, the momentum of the trigger components could be enough such that when the gun frame stops, the trigger keeps moving rearward, potentially causing a discharge. The trigger safety prevents this...the return spring on the trigger joint is heavy enough such that the momentum of the joint cannot overcome the spring -- so the trigger will never move rearward unless it's pulled. It can still be pulled with clothing.

Also: the M&P's striker is not technically fully cocked. You can consider it "mostly cocked", though. I think Smith says that it's 98% cocked...the ramp angle on the sear pulls the striker rearward before it releases it. With this design, I think they can still call it a "double action" handgun (to be able to sell to more departments).

Default Great explanation

Very clear explanation of the hinged trigger's function. The tab on Glock and many others does the same thing.

This has to be the least understood item on striker fired pistols. What I want to know is how they made it optional on the Sig P320 - is it still drop safe?

I am surmising that there simply isn't enough mass in the plastic trigger, or the trigger bar-parts, to move rearward far enough under an inertial jolt from a drop. Perhaps if it were dropped from the roof of a tall building...but not in normal usage.

I've thought the same thing. Some sort of trigger safety is pretty much standard (hinged or tang) on striker-fired pistols. Some even have additional safeties (thumb, grip, etc). It surprises me that Sig uses none of these...or apparently doesn't.
