AZ SB1535

Creates a new crime of "unlawful securing of a firearm" when a person with criminal negligence fails to prevent a minor under 17 from accessing a readily dischargeable firearm or leaves it where they know a minor would access it.

Requires reasonable precautions such as storing firearms in locked containers or using trigger locks to prevent minor access.

Provides affirmative defenses including when a minor uses the firearm under adult supervision for hunting or lawful purposes, in self-defense, through property trespassing, during agricultural work, or in activities specified in existing statute.

Classifies the offense as a Class 6 felony, escalating to Class 4 felony if the minor discharges the firearm and causes death or serious physical injury to themselves or another person.

Provides a 7-day grace period before arrest if the offender is a family member and the minor's discharge caused the minor's death or serious injury.
