Not to beat a dead horse, and IANAL, but - for good or for ill - the Framers were not delineating individual rights in the Bill of Rights. They were proscribing limits on the powers of the federal government.
State governments were allowed to regulate religious practice, assembly, speech, the ownership and carriage of arms, etc. as they saw fit up until the passage of the 14th Amendment. All the Second Amendment meant to the founding fathers was the assurance to each state that the other states would not have the power to band together and disarm their militias through federal legislation.
States could, and did, regulate the ownership and carriage of arms under their own constitutions and laws up until the 14th. We are still struggling with the conflict between decades of antebellum precedent and the full incorporation of the Bill of Rights. We should be very leery of the Supreme Court revisiting this topic, as they might just as easily reinterpret the 14th to suppress incorporation as shield individual rights from state regulation.
