Just as I would use my teeth for their primary function to deter a swab of my cheek, I fully intend on using my firearms for their primary function should some toady to a black robed fascist come knocking with demands that I allow confiscation of same.

There are many states where they make YOU swab the cheek for them to avoid bite potential. In many states it is a crime to refuse the cheek swab. If you refuse three or four burly guards will restrain you and take the sample forcibly. It happens all the time. On the somewhat bright side, in many states there is a restricton against keeping the sample. For example if you are arrested for a felony they will take a sample and run the DNA fingerprint against any open cases to see if you are wanted/fugative etc. If the search comes back negative they have to destroy the sample. Of course that can be changed with the stroke of a pen.
