I believe you are two Amendments off:

Amendment IV
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.

respectfully, you are reaching on this as well. determining firing characteristics and cataloging the gun is done prior to you getting the weapon. in what way does that information residing in a database violate the security of your person, house, papers and effects.

now, i think you (and having now read the original posters response to my comment) and the original posters issues lie with where having this documentation will lead. I understand and appreciate that angle, but the catalog doesn't violate the constitutionality, it would be with an unconstitutional use of the data.

am i splitting hairs, arguing semantics. probably. but we go off on the anti-guns when they attempt to wordsmith the constitution, we should make every effort not to stoop to that.
