Personally, I'd go to a gunshop an make buds with the owner an buy from them before Wally World
You pretty much don't have any choice any more, most Walmarts quit selling guns.[:@]
I know that on many of their upper end electronics, you're not getting the same product you would get if you went to a store like Circuit City
That's because they don't sell the same products.
If the model number is the same, you will be getting the same product.
