If the trigger reach is your problem you could try a Steyr M9A1, this gun have one of the best ergonomics and balance that I ever tried.... but I dislike (a lot!) the crapy unnatural shights... that anoying triangle thing.... in Venezuela it's imposible to find accesories and/or parts to the most popular brands, so imagine how difficult is the same issue with a not-so-popular brand like Steyr.... but if you find three dots or any other sightening system to this gun you will be fine with it I think, the other problem with it is the pull, a little bit hard pull (you can find more info HERE). I you find a Steyr M9 or M40 try it.
My girlfriend have small hands, the best fit that she ever had is from a Taurus, how about a Taurus 24/7 Pro? have you ever tried one?
