Stogey, check out the Kahr MK 40. Better caliber, small and extremely made. I would stay away from the Keltec, I know some officers who carried them concealed, since they had to qualify and actually shoot a sunstantial amount of ammo out of them yearly they didn't hold up.
Pick the one that fits you best and you shoot well. A particular grip angle/size may support your natural point of aim better than another. As long as you stick with a reputable manufacturer you should be fine.
XD sub-compact, tuarus millenium pro 9 mm, khar pm 9. The compact blocks are nice if you have tiny little girl hands. You'll still wana handle all the model you can get your hands on. Only way to tell which one will fit you the best.
