Spare Parts for an M&P

[SlipperyShooter]

Any suggestions for a "spare parts kit" for a M&P 9mm? I'd like to have enough on hand that I could quickly bring it back online in the event of a failure. What is most likely to fail and where would you buy that part?

Such a thoughtful contribution.

I'd go with a striker, striker spring, extractor and trigger assembly along with the tools to install them. I'd guess that anything else that may break is a million-to-one shot or requires major surgery.

Oh, and don't forget spare magazines.
