Colorado Gov. Jared Polis signed a bill into law on April 10 requiring people to obtain a permit and undergo safety training before they buy certain guns.

The legislation also bans the purchase and sale of devices that enable guns to be fired rapidly, including bump stocks.

“For folks who haven’t had any gun safety training, it’s very important that they get that, and this bill will make sure that people will get that education on how to operate the weapons safely and—just as important—how to store them safely,” Polis said at a press conference on Thursday.

Under the law, people cannot buy semiautomatic rifles or semiautomatic shotguns with detachable magazines unless they’ve completed hunter education training offered by the Colorado Parks and Wildlife and a “basic firearms safety course.”

Local sheriffs must sign off on completion of the course, with applicants also undergoing a background check and vowing not to violate state laws on guns.

Individuals who violate the law face a class 2 misdemeanor on the first offense and a felony charge on subsequent offenses.

Dealers found to have violated the law shall have their licenses revoked.

Everytown for Gun Safety, which advocates for gun restrictions, was among the organizations praising the bill.

Other groups said the bill infringes on constitutional rights.

Escalante said the group is reviewing its legal options.

“We’re not going to stand for it. We’re not going to allow Jared Polis ... and the legislature to force us to buy back our right to purchase the most commonly-used rifle in America,” he said.

Rep. Lauren Boebert (R-Colo.) also criticized the Colorado legislation.

Boebert and other Republicans called on the U.S. Department of Justice to sue Colorado over the law.
