Look into getting her a S&W 422/622....rock solid reliable, available with 12 shot magazines, under barrel design for very little discernible recoil, aluminum frame for light weight easy 15 second takedown, excellent crisp triggers.
I have one with a 4 1/2 inch barrel and one with a 6 inch barrel, both have thousands of rounds through them with only primer related problems. The machining work on them is top notch and even though they are discontinued they can still be found ANIB for under $450.00
The under barrel design makes them excellent suppressor host pistols. Parts are available on gunbroker but I've never needed to replace anything as of yet. They are fixed barrel pistols and as such tend to be dead nuts accurate. I've never found any reason to complain about these fine little pistols.
