Rep. Bobby Payne, R-Palatka, and Rep. Tyler Sirois, R-Merritt Island, filed the proposal (HB 1543) as lawmakers prepared to begin the annual legislative session Tuesday.
Lawmakers in 2018 increased the minimum age from 18 to 21 to purchase long guns after former Marjory Stoneman Douglas student Nikolas Cruz, then 19, used a semi-automatic rifle to kill 17 students and faculty members and injure 17 others.
Federal law already barred people under 21 from buying handguns.
The Republican-controlled Legislatureโs 2018 decision was highly unusual in a state that had expanded gun rights over decades. The National Rifle Association immediately filed a challenge in federal court, arguing that the law violated the Second Amendment.
Chief U.S. District Judge Mark Walker in 2021 upheld the constitutionality of the law. Walker said he was following legal precedent, though he also described the case as falling โsquarely in the middle of a constitutional no manโs land.โ
The NRA appealed to the 11th U.S. Circuit Court of Appeals. A panel of the Atlanta-based appeals court heard arguments in May but has not ruled.
During the arguments, NRA attorney John Sweeney contended that 18-year-olds in Florida โdo not enjoy the same freedoms guaranteed the rest of the adults in this countryโ by the Second Amendment.
But in a document filed in district court, attorneys for the state wrote that people ages 18 to 20 are a โparticularly high-risk groupโ and pointed to scientific evidence about impulsive and risky behavior.
โEmpirical evidence bears out that because 18-to-20-year-olds are uniquely likely to engage in impulsive, emotional, and risky behaviors that offer immediate or short-term rewards, drawing the line for legal purchase of firearms at 21 is a reasonable method of addressing the Legislatureโs public safety concerns,โ the document said.
In his ruling upholding the law, Walker, in part, focused on a landmark 2008 U.S. Supreme Court case known as District of Columbia v. Heller. While the Heller case is broadly considered a major victory for gun-rights supporters, it also said certain โlongstanding prohibitionsโ about guns do not violate the Second Amendment, according to Walkerโs ruling.
The Heller case cited prohibitions on such things as felons and mentally ill people possessing guns, Walker concluded that restrictions on 18-to-20-year-old people buying guns were โanalogousโ to the restrictions cited in the Heller case.
As of mid-afternoon Monday, a Senate bill had not been filed to lower the minimum gun-purchasing age from 21 to 18, according to information on the Senate website.
Guns were already expected to be a major issue during the 60-day legislative session, as the House and Senate have started moving forward with proposals that would allow people to carry concealed weapons without licenses.
