My son wanted a Versa Pak Combo or a Rossi Matched Pair, but at 12 years old, the youth stock was a little small for him. I bought a Pardner .410 and a Sportster 22LR for him instead. It wasn't that much more expensive than the Versa Pak, and now he has two guns that are both capable of getting additional barrels.
If you bought a Pardner and a Sportster, your Grandaughter would need the youth stocks (eventually). They are available from NEF for $28 (walnut) and $30 (synthetic). When she gets bigger, you could put the original stocks back on. When she has kids of her own, she could put the youth stocks back on and tell her young ones that they can learn to shoot with the guns that her Grandpa gave her when she was just a baby!
