These seem reasonable

The first of the new bills would require secure storage of firearms, and would in fact penalize people who do not comply. In homes and businesses, under this bill, gun owners would be required to either store their weapons in safe boxes or place locking devices on them. The bill offers some flexibility in terms of what the storage looks like, as long as it’s secure enough to be accessible only with the use of a key, combination code or biometric data such as fingerprints. Failing to comply with these rules would be a class 2 misdemeanor under the proposed bill.

The second bill is also starting in the House and will be sponsored there by Sullivan and Rep. Sonya Jaquez Lewis, D-Boulder County. The bill seeks to require that anyone who becomes aware that a gun they own has been either lost or stolen to report that loss or theft to law enforcement within 48 hours. It, too, would create new criminal punishments for violators: Failure to comply would be treated as a petty offense, punishable by a small fine, in the first event. But second and subsequent offenses would be treated as class 3 misdemeanors
