I have smallish hands too. Here are my observations through the years
1911 - best trigger possible on a handgun and its thin to begin with.. get some thin grips and it's even better.
HK P30 - It really doesn't get any better than this, you can adjust anything about the grip size that you want. Comfy as hell. Trigger sucks
Walther PPQ - See P30, not quite as adjustable, but feels just as good, and unlike the P30, best in class trigger. My universal pick for new shooters.
Any Sig with the E2 grips. - These are damn near perfect for me, YMMV. If you like DA/SA go with this otherwise, PPQ.CZ-75B with VZ grips - Almost as good as Sig but DA triggers are harder to deal with due to the longer reach required, on my single action model, it's not a problem, so there's that route.
Glock 17/19 - Seriously, try one, amazingly comfortable pistol to hold and shoot for those with small hands. DO at least try the Kool-aid.
Your pick of the M&P is also good, just get an APEX kit if you don't like the trigger.
And to those recommending a BHP... don't do that to a new shooter, it's just mean.
