Any double action will be too stiff and if it's not stiff it will not be reliable.
Any pistol in .22 will likely be blowback and will have a heavy recoil spring. 22 autos are still not very reliable.
What you need to get her is a single action revolver. I have a Bearcat that is easy to carry, easy to cock and easy to fire. Load her up with some CCI Stingers and she will be well armed.
