extended mag for M&P 9c

[drjpark]

I would like to know if the standard 9mm M&P 17 round mag will feed properly in the 9c. It clicks in ok, and I have fired 5 rounds with a friend's mag. Should I buy a new one?

They will work, there's a sleeve called "X-Grip" that slides over and fills out the grip real nice, Speed Shooters, MidwayUSA and others have them.
