I have owned a 45c and it is a great little .45. With the size S grip in, she should be able to handle the weapon. The M&P 45c still has almost a full size grip for someone with smaller hands. I would recommend trying to get her one to try it on for size. I think that she should not have any problems handling the 45c. It still has a larger sized grip even though it is listed as a compact. Even at that, she could use the pinky extension mags. The M&P is a very soft shooting .45. I personally hate a Glock .45 ( Still own a few Glocks just not in .45 ). Have tried everyone of them, even the SF versions and they eat me alive. The M&P, I would shoot all day long.

Am also curious as to how this turns out. Please keep us posted.
