The San Francisco are giving $500,000 toward advocating what they are calling "common-sense legislation" to ban bump stocks and any other mechanism that allows for the conversion of a semi-automatic weapon into an automatic weapon as well as armor-piercing bullets and gun silencers.
Per ESPN, the Niners announced the creation of the "Pledge for a More Understanding and Safer America" with representatives from law enforcement groups in New York, Los Angeles, Portland, Santa Clara County, Sacramento, Long Beach and Oakland.
Beyond that, the Niners and the law enforcement groups are also planning to create public service announcements intended to improve police and community relations around the country.
York said the campaign for the gun legislation was inspired by the mass shooting in Las Vegas that left 59 dead earlier this month.
"Police officers don't use bump stocks and police officers are the ones that are carrying weapons to help protect and serve our country and it seems insane to me that a citizen can buy something like that and take something that was awfully horrific but magnify that and make it so much worse," York said. "I think those are the things that if we want to keep our community safer, if we want to keep stadiums safer and entertainment venues around this country safer, we need to be very vigilant about things like bump stock and about other things like that that can really put all of us in extreme risk and extreme danger."
