PLEASE Skip the 357's!!! As mentioned even seasoned shooters don't enjoy shooting them in a J frame. Putting 357s in that gun to shoot is almost a certain recipe for her never wanting to shoot it again. Give her light 38 target loads to get accustomed to. Then gradually (!), once she's comfy , try some +P 38 loads. Then ASK her if she wants to try 357's. That way she can find her own comfort level. Trust me , she'll be allot more proficient (and able to protect herself) with ANY 38 load if she is proficient and comfortable with the gun. ( Read: a J frame stuffed with 357's is useless if it's home and she's afraid of it.)
In reality, 38 +P is all she'll ever need anyway.
p.s. If you doubt any of this, try shooting 50-100 rounds of any 357 out of that gun before asking her to. ( Don't even have her there as the muzzle blast will likely scare her.)You'll understand then.

pps. Great little gun/gift BTW!
