Noob here ...
My wife just got her first, and after picking up and holding a few of my suggestions she decided she wanted the M&P Shield in 9mm. I saw it mentioned earlier in the thread about the SR9c. I have one, but she doesn't like the size of the grip - she has relatively small hands. So a week or so ago the Shield arrives at my LGS. Brought it home and cleaned it, and went to the range. She loves it, feels she made the right choice.
