I have a brand new Winchester SX3 Compact with a nice short 13" LOP that I'd like my 10 year old daughter to start shooting next year. She will be 11 years old by then. The stock fits her nicely but the barrel is 28" and that's a bit long and heavy for her. Anyone know if I can get a 24" barrel from Winchester? Or better to try and trade the SX3 for another one that has a 24" barrel?
