Go with what feels best for YOU regardless of what everyone else suggests. Most are going to simply suggest the one they have/use and may not even have any first-hand exp. with another. Consider manual of arms, design (hammer vs. striker). Look at holster options before buying as well and consider that your first choice for a holster probably won't be the last.
I have a M&P40 (inherited) and I'd say it's too large for most for a good concealed carry pistol. To each their own though as what works for one, might not for another.
I prefer my SP101 for a carry gun but also have a P7M8 and a P2000SK for that purpose available as well.
Another very worthwhile aspect to this would be to upgrade your training as well. Make it GOOD stuff not the basic thinly blanketed stuff most settle with as a minimum. Very few put as much into this aspect as they do the gun which is unfortunate. If you're serious it should be equal.
