What spare parts to buy?

I’m getting some stuff from Midway for my M&P9 and figured I should pick up some spare parts, however, I’m not sure what would be handy to keep on hand. I would appreciate some suggestions.

Well judging from Todd’s 50,000 torture test the only spare parts you should need (aside from magazines of course) are replacement springs.

LOL point taken. I think I will buy an extra striker for dry firing and maybe an extra extractor and recoil spring.
