My newly acquired M&P 45 M2.0 did not come with a thumb safety. All the available models with a thumb safety did not have the new version trigger, which I wanted, so I ordered the thumb safety lever, detent, and detent spring from Numrich and installed them myself. Initially I contacted the Performance Center to ask them if I sent the pistol in for their trigger job if they would install a thumb safety for me, but they refused. I don’t know why. It was super easy and hardly took any time at all. While I had it apart I also installed an Apex Ultimate Striker Block and polished the cam on the trigger bar that slides over it with a felt bob on my Dremel and a little Flitz. The whole trigger job only cost me $40 in parts and a few minutes in labor, but the trigger is just as good as the one on my 10mm Performance Center now. The trigger now has a nice crisp 5lb pull with no gritty feeling in the takeup. Perfect for a service/home defense pistol IMO.

All my M&Ps have a thumb safety. There are frame plugs for those who want to remove the safety. Would be curious if those cuts are on those coming from the factory w/o a safety. That would be the 1st thing I would check on yours and probably explain why the factory wouldn't comply if the cuts aren't there. They'd most likely have to use a new frame, transfer the serial number, possibly a new sear housing, etc..
 
I installed a safety in my M&P .45, too. It’s not a big job. I can’t imagine why S&W wouldn’t help you, but I suppose their legal department thinks it might put them at risk in some way. :rolleyes:
 
The frame plugs come on many of the non-safety polymer framed M&P models with a few exception's. (not on Shields, for example)

So as Mike-AK did, you pull the sear housing out, pop out the plugs, install the manual safety parts and drop the sear housing back in.

I still have the frame plugs, and it is a 10-minute job or less to pop out the sear block, remove the thumb safety parts, and reinstall the plugs if it ever has to go in for work. Not to mention they are S&W parts, and the sear blocks are all the same.
 
just to clarify,

My shield 45 nts does not have the cutout for the thumb safety. In order for me to install a thumb safety I would have to cut a slot in the frame which would be a project for me to do properly. I have been looking for a frame to buy at a reasonable cost that has a thumb safety or a cutout. No Luck, guess I'll be fine without. Love my 6k round shield 45 so far!
