I finaly going to get a new shotgun but I want something "cool." I am looking to buy a 12 ga. shotgun in the 300 to 400 dollar range. I going to dub it a home defense shotgun so I want as shot a barrel as CA law permits. What ever I get I want to be able to modify it to include a shoulder stock-pistole grip combo. If possible I would love to have a semi but a pump would be fine. I don't need a fancy wood finish either a durable black plastic would be perfect.
