M&P Safety?

The trigger design is considered a safety aspect in that it requires a deliberate pull to engage properly and fire. Besides those, none.
If carried in a good holster that shields the trigger the chances are astronomically slim that the gun will fire without some human input. In short I find it a safe gun when handled correctly.

There is a firing pin block safety that is engaged at all times. The only time the safety is disengaged, is when the trigger is pulled.
They are safe guns, the safeties are there, they are internal, automatic, and are only disengaged by trigger pull.
The gun is double action only by the slightest of margins. It is 95% precocked when a round is chambered, or the slide is moved approx. 1/4". The firing pin safety is engaged 100% of the time as a block in the firing pin channel. A lever attached to the trigger bar moves across a plunger that removes the block from the channel while the sear block is rotated out of the way of the precocked firing pin.
There are safeties, and it is a safe gun with trigger finger discipline.

Paragon1 hit it on the head. Think of the internal safety system as that of a modern revolver. No amount of banging around is going to set it off. I personally love the "point and shoot" revolver like simplicity and slim profile of the M&P without the thumb safety but it's a personal choice.
p.s. If your worried about catching the trigger on holstering, just hit the mag release during that process and the trigger is disabled.

I believe not all MP pistols have the magazine disconnect feature as standard. Is it not an optional item???

My M&P40C will fire without a magazine in the gun(says so on the slide). I believe the gun can be ordered with or without the magazine disconnect as well as with or without an internal lock.
This pistol is as safe or safer than a double action revolver.

Neither of my M&P's have a mag disconnect...they'll shoot with no mag in them. I think the disconnect was intended for the LE market (or maybe I've got it backwards) but anyone can get them.
I have the thumb safety on both of mine, but it's primarily because when I got my M&P40 all they had was the one with the thumb safety. I got used to it and kind of like it. When I bought my M&P40c Friday I could have had with or without, and I got it with the safety just so they'd both be the same. It's in a perfect location where my thumb just sweeps it off as I'm coming up to fire. Worst comes to worst it's easily removed.

This is only true if the gun is equipped with the mag disconnect. An easy way to tell if a pistol is equipped with this feature is to see if the slide has the words "capable of firing with magazine removed" laser engraved on it.

Firing pin safety prevents inertial discharge if the weapon dropped on its muzzle.
Trigger safety prevents intertial discharge if the striker fired weapon is dropped on its rear.
Disconnector prevents out-of-battery firing.
Sear disconnect lever takes away requirement to pull trigger for disassembly.
Loaded chamber indicator allows inspection of chamber without pulling slide back.
Internal lock (on pistols so equipped) allows disabling of the weapon with a key.
Magazine safety (on pistols so equipped) prevents trigger from firing weapon without magazine in place.
Thumb safety (on pistols so equipped) allows pistol to be disabled unless the lever is in the down position.
I think that is all as far as mechanical safeties.
Oh, forgot one - If you do not wish to fire pistol, keep finger off trigger. Use your brain as the best safety is your brain. Safety lies between the ears, as the Colonel used to say.

The thumb safety only blocks movement of the trigger.

WHAT!
I thought that you can still pull the trigger but noting would happen!
Oh well, I just ordered my M&P with the thumb safety......

Nope.
The safety (highlighted in red) in the up/on position, blocks rearward movement of the trigger bar (blue). Once the trigger bar is blocked, the trigger can not be pulled. In the pic, the safety is off in the down position. The trigger bar can freely move rearward over it.
What you thought is what happens in guns w/magazine disconnect when the trigger is pulled w/no mag inserted in gun.
