And you have to admit, it is not beyond the realm of possibilities for the trigger on an M&P to get inadvertently caught on something.
Thank you Gentlemen:
Well that was quick and I appreciate your assistance. It's not that I don't understand the concept behind the pistols design, it's just that one becomes so accustomed to certain aspects of the semi's, that when they disappear one can't help feeling that something fundamental is missing - probably like leaving the house without your pants.And you have to admit, it is not beyond the realm of possibilities for the trigger on an M&P to get inadvertently caught on something.
There is already a safety on the M&P. It's called your trigger finger. If you do not stick your trigger finger on the trigger, the gun will NOT fire!
I have shot thousands of rounds thru mine... drawing from concealment holster, never an issue. My pistol have never gone off without my finger squeezing the trigger first.
Safeties are good for those who have minimal exposure to firearms and have thus not developped muscle memory and stick their fingers thru the trigger guard prematurely.
But to answer your question directly, NO, you can not add a safety to an M&P40
The M&P45 however does offer an optional safety.
It's not that I'm bashing the M&P, I have one and I like it very much thank you. I would have the same concern with the Glock or any other pistol of similar design. Who's to say that "with a manual safety" that the manual safety wouldn't inadvertently get disengaged and the trigger get caught up on something? There is very little that can be said with absolute certainty. For myself, personally, I would feel more comfortable with the addition of a manual safety. Obviously, I felt differently when I made the purchase and now I've changed my opinion. It's as simple as that, I am not advocating anything, I just asked a simple question and responded to the replies.
When it comes to safety it is best to work on the premise that whatever can go wrong will go wrong. If you do you are half way there to ensuring you have done everything possible to prevent an accident. History has shown us that sometimes bad things happen to good people. Take Care, Bob

Any pistol with out a manual sear blocking safety can go off when reholstering if it catches clothing.

Thanks Bullwhip, that's good to know as I've never handled the manual safety version myself, I'll keep it in mind to try it out next time I get the chance. As Wendell pointed out, getting one installed isn't an option, so should I decide to go that route it would open up a whole slew of possibilities: like the CZ 75B (sweeeeet), or some other such thing. And guys/gals, the best safety is not to carry the damn thing with a round chambered, right!![]()

Good advice Bob. That being the case, why rely on the manual safety or the addition of one? Foreign objects in the trigger guard can cause the firearm to, well fire. Your example of a shirt tail in a holster is flawed on several levels. For starters. If your aren't clearing your cover garment before holstering you're wrong. Second, if you feel resistance when holstering you don't continue to force the pistol into the holster. There's a video of a guy trying to actuate the trigger on his Glock with his shirt to no avail. He went so far as to stuff his shirt tail through the trigger guard then yank on his shirt vigorously, all without a single "click" of the firing mechanism. I'll try and dig it up.
