The new regulations come on the heels of a mass shooting in Boulder earlier this year.

Bill SB21-256 allows cities in Colorado to establish their own gun regulation, overwriting a previous state law that "prohibits a local government from enacting an ordinance, regulation, or other law that prohibits the sale, purchase, or possession of a firearm." While the new law gives local jurisdictions more latitude to set their own gun control regulations, it does prohibit them from enacting regulations that are "less restrictive" than state law.

Ten days before the March mass shooting that left 10 dead, a Boulder County District Court judge blocked the city's ban on assault weapons and large-capacity magazines.

The judge ruled that the 2018 law violated a previous law from 2003 that made gun regulations a state interest to prevent "a patchwork of inconsistent local laws involving firearms.".

The third bill requires the Office of Gun Violence Prevention within the Department of Health and Environment to conduct public awareness campaigns that "educate the general public about state and federal laws and existing resources relating to gun violence prevention." .

Colorado Senate Majority Leader Stephen Fenberg said that the newly signed legislation is a step towards creating a "framework that, over time, will result in saving lives."

"There's something that I think a mass shooting does to the psyche of a community collectively, even if you weren't individually involved or impacted and it really kind of disrupts the way you move through your daily life through your world," he said at a signing ceremony Saturday
