I am thinking of purchasing a Rossi combo for a bag around/throw in the trunk gun. I see on their website they have a 12 gauge/.22LR adult stock combo. The only thing I am concerned about is that it has the synthetic stock. I would think that gun would kick pretty bad with a synthetic stock. If I was to buy this is there a place I can buy a wood stock to fit it to add some weight to it? Also if I bought the 20gauge/.22LR youth combo can I get a wood adult stock for it? Does anyone know what the LOP difference is between the youth and adult models?
