+1 on the Comptac. It is a comfortable, stable, and thin holster that conceals remarkably well. You can also get one within a few days of ordering. I first carried my M&P in a Desantis Cozy Partner. It is very comfortable but the Comptac is MUCH more concealable and stable. Reholstering is also much easier. I recommend a hard holster (kydex or reinforced leather) when carrying a weapon like the M&P which has no safety or hammer to help prevent an accidental discharge while re-holstering.
