Jeffery8mm, spend a couple of bucks more and buy her her own .410 Pardner at Wal Mart, perhaps even a youth model or Tamer if they fit her better. Or you could look around for a used one for between $50-$70.
I suggest a trip to Wal Mart, take your "calming" pills and pack a lunch because they are know nothings there and the ordereing process takes a looooong while, but persevere and order a new .410 for her. Between $79 and $89 at Wal Mart. They may(!!!) be willing to call around and see if a store near them has one in stock, remember, never, never, give up and you will eventually get through the process.....<><.... :wink:
You could of course do what others here have done and try to buy a used barrel from someone on this forum or E-bay and hope it fits your reciever, and if it does not fit then fit it yourself, it's not all that difficult and there are many here to help. If you find the barrel you bought cannot be fitted to your reciever (highly unlikely but possible) then there will always be someone here to buy it from you.......
