I don’t think a shop can sell a gun with major issues(such as a bulged barrel or cracked frame) due to liability. With that being said, it could slip through the cracks. I would do a function check and give it a good visual inspection. If it’s just cosmetic, that’s one heck of a price. Like others have said, almost too good to be true.
