i am thinking about buying a used xd 9 Tactical from a friend .. He sais he has had roughly 200 rounds through it and will sell it for 350 since he bought a new 45 revolver .. What im wondering though .. When you buy a used gun does the lifetime warenty come with it? I know with things like cars and some other things its not the case.. but am just wondering if by chance it might be different with guns.. Thank you much for any replys.
