If she has a choice, a 4th Gen Glock 37 .45 GAP. Small grip diameter, 10+1 capacity of .45 caliber round. Very reliable, as a former officer - if I was to go back in uniform tomorrow and given a choice of duty gun - the Glock 37 would be at the top of my list for possible guns. I have smaller hands and this combo is pretty hard to beat. Good luck to her with her choice.
