AZ SB1508

Creates a new criminal offense for unlawfully securing a firearm, making it illegal for a person to negligently leave a readily dischargeable firearm accessible to minors under 17 years of age.

Establishes affirmative defenses including when the minor uses the firearm under supervision of an adult for hunting or sporting purposes, in lawful self-defense, while engaging in agricultural enterprises, or if the firearm was obtained through trespassing.

Classifies violation as a Class 6 felony, but elevates 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 can occur if the firearm owner is a family member of the minor and the minor's discharge of the firearm caused injury or death to the minor.

Defines "readily dischargeable firearm" as any loaded firearm regardless of whether a round is in the chamber, and "family member" to include blood relatives, adopted relatives, current or former dating partners, legal guardians, and those residing in the same household within the previous year.
