Current law defines a multiburst trigger activator as either a device designed or redesigned to be attached to a semiautomatic firearm, which allows the firearm to discharge two or more shots in a burst by activating the device, or a manual or power-driven trigger activating device constructed and designed so that when attached to a semiautomatic firearm it increases the rate of fire of that firearm. This bill would state that the existing definition of a multiburst trigger activator includes a bump fire stock or bump fire stock attachment.

RE: SB 1346 (Jackson) Multiburst trigger activators
AAP-CA Position: Support

Dear Senator Jackson:

The American Academy of Pediatrics, California (AAP-CA), representing over 5,000 California pediatricians, strongly supports your proposed legislation SB 1346 (Jackson). This bill would prohibit the manufacture, importation, sale, transfer, or possession of bump fire stocks.

The Centers for Disease Control reports that in 2016, 4,927 children and youth age birth to 21 years, died from firearm injuries, and another 21,764 were non-fatally injured. Firearm related homicide and suicide are second only to motor vehicle crashes as a leading cause of death among teens and young adults. Although only a small proportion of overall firearm-related morbidity and mortality, recent mass shooting have highlighted the substantial harm that assault-style weapons can incur by a single shooter in a short period of time. The catastrophic shooting in Las Vegas last year left 59 dead and more than 500 injured. Using a bump stock attachment similar to the ones used in Las Vegas enables a shooter to fire 400 to 800 rounds per minute, essentially allowing a semi-automatic weapon to function as a fully automatic machine gun.

SB 1346 would include bump fire stocks and bump fire stock attachments in the existing ban on multiburst trigger activators. This would be in alignment with California law banning assault weapons, and devices that allow firearms to function as assault weapons. SB 1346 will help protect our children from future mass killings.

Pediatricians across the state support SB 1346 (Jackson). We thank you for your leadership on behalf of the health and well-being of children, youth, and families in California.
