Probably a useless gesture in terms of coming from a Joe Citizen like me, but I already contacted State AG Office this morning highlighting that the proposed actions are in direct conflict with CRS 29-11.7-103:

Regulation - Type Of Firearm - Prohibited.

A local government may NOT enact an ordinance, regulation, or other law that prohibits the sale, purchase, or
possession of a firearm that a person may lawfully sell, purchase, or possess under state or federal law. Any
such ordinance, regulation, or other law enacted by a local government prior to March 18, 2003, is void and
unenforceable.
