Carry gun for my wife?

i am gonna buy my wife a carry gun she likes my kimber 1911 but she also has small hands she has shot a 9mm a40s&w and my 45 of course and does well with them all so should i get her a cdp just like mine or maybe a pro model in the 4in version or would it even make a difference or should i try her on a glock or something which she has shot as well just a question for some of you gun guys and gals out there
