Denver, Colorado - Colorado has positioned itself as one of the strictest states for gun control in the United States with the enactment of the most comprehensive gun safety legislation in its history. Governor Jared Polis signed the new law on Thursday, mandating universal background checks and mandatory training for the majority of semi-automatic firearms.

The passage of this bill comes despite staunch opposition from gun rights advocates, including Colorado's Republican federal lawmakers, who argue the legislation infringes upon constitutional rights.

State Representative Tom Sullivan, the bill's sponsor, emphasized that the law will save countless lives. Sullivan's son, Alex, was a victim of the 2012 Aurora theater shooting. "We decided not to be silent or indifferent. We will speak out and stand with everyone who suffers from the public health crisis of gun violence," Sullivan stated, reflecting on the significance of the bill's enactment. Since becoming a state legislator in 2019, Sullivan has been instrumental in passing approximately 20 gun-related bills. This latest legislation represents the most sweeping regulations to date, although it did not include a ban on so-called 'assault weapons' that Sullivan initially sought. Governor Polis negotiated several amendments, including exceptions for individuals undergoing broad background checks.

"This bill allows people who want to purchase firearms to be able to purchase the firearms they want, while also ensuring that they have the appropriate training," Governor Polis said at the signing ceremony.

However, the new law places limitations on who can qualify for training. Individuals must pass a background check and obtain a qualification card from their county sheriff, who can deny the card if the individual is deemed a risk. Those seeking training must complete a 12-hour safety course certified by the Colorado Parks and Wildlife Department, reduced to four hours for those who have completed hunter education. Subsequently, their names will be registered in a state database, allowing them to purchase firearms from licensed dealers after passing an additional background check.

Huey Laugensen of the Colorado State Shooting Association expressed concerns that "this bill will deny many people the opportunity to own firearms." He argued that the costs associated with obtaining permits, training, and background checks infringe upon citizens' constitutionally protected right to keep and bear arms, vowing legal action. "Governor Polis may think he's scored points with anti-gun groups, but he's just given us a powerful rallying cry. This fight has just begun, and we will fight it to the end," Laugensen asserted.

Representative Sullivan responded, "There is still more work to be done. When it comes to taking action against the public health crisis of gun violence, I will always be at the forefront, making my voice heard." He pledged to continue pushing for further regulations.

The new law also prohibits the use of rapid-fire devices, commonly known as 'bump stocks,' which modify semi-automatic firearms to function like automatic weapons. The regulations primarily target semi-automatic rifles such as the AR-15 and AK-47, known for their detachable magazines allowing for rapid reloading. Traditional hunting rifles and most handguns are exempt from the regulations.

These regulations will only apply to firearms purchased after August of next year.

Governor Polis stated that efforts are being made to keep training costs below $200 and to consider assistance programs for individuals facing financial hardship. Exemptions for active-duty military personnel and certified law enforcement officers are also under consideration.

Colorado residents will not be able to circumvent the new regulations by purchasing firearms in other states, as federal law requires gun dealers to adhere to the laws of the buyer's state of residence.

US Gun Control Landscape: Colorado's latest legislation is considered among the most stringent gun control measures in the US. Federal gun control remains minimal, with significant variations in regulations across different states. California, New York, and Massachusetts have relatively strong gun control laws, while states like Texas and Arizona have fewer restrictions on gun ownership.

The Gun Control Debate: Gun control in the US is a deeply divisive issue, primarily due to differing interpretations of the Second Amendment's 'right to keep and bear arms.' Gun rights advocates emphasize individual self-defense and liberty, while proponents of stricter gun control prioritize public safety and reducing gun violence.

Colorado's Past Gun Control Efforts: Colorado has a history of strengthening gun control measures, particularly after the Aurora theater shooting, which led to bans on high-capacity magazines and enhanced background checks. This new law is an extension of these efforts, representing a more direct regulation of semi-automatic firearms.

Potential Legal Challenges: In addition to the lawsuit threatened by the Colorado State Shooting Association, the new law is highly likely to face legal challenges regarding its constitutionality under the Second Amendment. The validity of the law will likely be determined by federal court precedents and future judicial decisions.
