Supposedly most plastic weaponry and ceramic ones will show up on x-ray... although you could probably come up with ways to hide / obscure them effectively.
Even then, I would be doubtful that any sort of hijacking would succeed in the US; pax are going to mob anyone acting threateningly regardless of the weapons that person possesses.
