Your iPad was replaced because it is cheaper to do that than repair it (a repair would generally consist of replacing the board or the screen anyway).Actually, in Florida they do. There's a lemon law on cars. This situation is a little different than that though.
However, many companies will replace a defective item as opposed to repairing it, to maintain customer satisfaction. My iPad 3 was replaced instantly when it had a defect the first week, even though they didn't have to. And Apple even gave me the next model up memory wise. Lenovo does that too.
I think you need to reread the lemon law.
I don't understand the OP's distrust of a repaired gun. By his logic, he should also distrust a properly functioning gun because there might be a hidden defect that hasn't reared its ugly head yet. If you put a few hundred rounds through the returned gun with no issues, then you are good to go.
