I have a 1300 Turkey with laminated wood stocksthat I bought new several years ago and have killed several turkeys with it. I absolutey love this gun and will never part with it. As far as chokes it came with 3 or 4 but I bought a Hastings .655 for turkey hunting. And yes I believe you are right about the Browning Invector chokes fitting the Winchesters as long as it is not the Invector Plus chokes. You should be able to order chokes from Cabelas or Bass Pro or find them at local gun shops.
