Less than a month after 10 people were fatally shot at a Boulder King Soopers, Gov. Jared Polis signed two gun bills into law on Monday.

One, HB 21-1106, requires people to secure their firearms when they’re not in use or face a Class 2 misdemeanor charge, punishable by up to a year in jail, a fine of up to $1,000 or both. The other, SB 21-078, mandates that lost or stolen firearms be reported to authorities within five days or face a civil infraction of a $25 fine or a misdemeanor (carrying a fine of up to $500).

Polis called the measures common-sense action and “best practice for responsible gun owners.”

The lost or stolen firearms bill, named the Isabella Joy Thallas Act after a 21-year-old woman who was fatally shot in Denver by a man who stole a police sergeant’s personal firearm, takes effect 90 days after the 2021 legislative session adjourns.

“It’s the right thing we do for the people we care about,” Polis said. “Many Coloradans already report lost or stolen guns. Now they have to. In many cases, this opportunity to save a life is just a phone call away.”

The safe storage law starts July 1. Polis said responsible gun owners know it’s important to store a weapon safely “so kids can’t get a hold of them with a tragic outcome.”
