I like the M&P line of pistols. I own 3 of them. One thing I like besides the reliability is a follow up of what mrbb said above. The M&Ps (except for the Shield and another model I can't think of right now) have interchangable backstraps for to change the grip size to fit your hand. A lot of people on here say it should "fit your hand" but some don't really know what that means. And I was one of those people until a few years ago when it was explained to me by a long time handgun instructor.
