This is why I never considerred ankle carry. If you need it you don't have time to waste. I carry IWB and carried in pocket when possible.
There really isn't a reason to buy a new gun. Just get a good pocket holster and keep moving on. Of course a 9 in the pocket is better than a .32 in the same place.
You handled things very well. You protected your daughter in the best way you could. You went home safe and so did she. To me that is the perfect outcome.
Here's my credo: There are no good guns, There are no bad guns. A gun in the hands of a bad man is a bad thing. Any gun in the hands of a good man is no threat to anyone, except bad people.
