RE: Wal-mart guns?
Walmart can also custom order almost any firearm you want. They have a book you can look at and order from. You are limited to just what they have in stock. At least they used to be that way, they are changing a lot of things relating to hunting and firearms.
That being said I would still suggest getting a gun from a local gun shop. Especially if you have any questions. They will mostly likely know a lot more than the kid or girl behind the counter at wally world. It might cost you a bit more, but in the end it will probably be worth it.
