May I ask why you are against polymer pistols? I mean the Glock and the M&P line up are proven. More LE Agencies use them than anything else.
I know that Sig's are another popular choice, but damn I hate the factory trigger reset of a Sig. (Just my personal preference)
May I suggest you try renting a few at the range, and seeing what you like best then?
Most polymer pistols have adjustable back straps to accommodate smaller or larger hands.
Just something to think about. Good luck with everything....
