DENVER (KDVR) — On Friday, the Colorado Senate voted to concur with amendments adopted by the House on a bill that Democrat legislators have touted as a way to “fully implement and enforce Colorado’s existing high-capacity magazine prohibition.”
That means the bill is now headed to Gov. Jared Polis’ desk where he could sign the measure into law.
The bill would require anyone in Colorado after Aug. 1, 2026, to have a permit and complete firearm safety training to purchase semiautomatic firearms that accept detachable magazines. The bill would also prevent any sales of rapid-fire conversion devices, which allow the user of a semiautomatic gun to treat it more like a fully automatic weapon. These devices include bump stocks and binary triggers.
“High-capacity magazines are what put the ‘mass’ into mass shootings, which is why over a decade ago Colorado Democrats passed legislation to prohibit magazines that hold over 15 rounds of ammunition,” said Sen. Tom Sullivan, a Democrat representing Centennial and sponsor of the bill, in a release. “This legislation is another in the list of policies I have worked on to develop evidence-based solutions and reduce gun violence of all types. The people of Colorado have mandated that we do something about the public health crisis that is gun violence, so that’s what we’re going to do.”
Opponents of the bill said that the measure would cost millions of dollars for local sheriff’s offices and Colorado Parks and Wildlife to administer the new requirements.
