The SR22 is a great gun. Your dtr. will love it
I bought one for my dtrs. back in June of 2012, liked it so much, that I bought one for myself this past June.
I had a 22/45 for many yrs., also a great gun, but definitely harder to break down and clean. I shot the barrel out of it after more than 30,000 rounds. Sent it back to Ruger with the required $15.00 check. They put a brand new barrel and extractor on it, and returned it and my check...lol Can't ask for better customer service than that.
When you get the money, don't hesitate to pick up the SR22, she will love it. Both of ours shoot everything.
As always, stay safe.
