I don't see where it would be a straw purchase. In the initial transfer the father would be the actual purchaser of the firearm. Then the firearm is transferred to the son at an MD FFL and the paperwork requirement/waiting period is observed. In the MD transaction the son is the actual purchaser of the firearm.
I would think it would only be a straw purchase if they skipped the MD FFL step to transfer it to the son. The father is not giving it to the son until it has been transferred legally.
