You used to be able to have a 22" Youth 12ga fitted at the factory, but I think they no longer have or offer them. You will most likely have to make your own. Lots of guys here have done and there is no shortage of tips and ideas for a shorty 12ga. Must be some big snakes if you need a 12ga. The new 20ga Tamer is 20" and Modified choke and would work well on snakes and lots of there game and critters too. A good alternative. Just my 2 cents.
