What: Firearms Policy Coalition (FPC), joined by the Colorado State Shooting Association (CSSA), filed a new federal lawsuit, Elliott v. Denver, challenging Denver’s ban on so-called “assault weapons” and Denver’s and Colorado’s bans on magazines that can hold more than 15 rounds. The filing comes the same day the U.S. Supreme Court granted review in FPC’s Viramontes v. Cook County challenge to Cook County, Illinois’s “assault weapons” ban.
Who: The plaintiffs include FPC, CSSA, and individual FPC members. They are represented by David H. Thompson, Peter Patterson, and William V. Bergstrom of Cooper & Kirk, PLLC.
When: June 30, 2026.
Where: The lawsuit was filed in the U.S. District Court for the District of Colorado.
Why: The challenged bans unconstitutionally prohibit peaceable people from acquiring, possessing, and using firearms and magazines protected by the Second Amendment. This lawsuit is part of FPC’s nationwide strategy to eliminate bans on constitutionally protected arms throughout the United States.
Quotes:
“We filed this lawsuit to end Denver and Colorado’s war on gun owners and force these tyrants to respect the Second Amendment, whether they like it or not. This case is another critical step in our nationwide campaign to eliminate tyrannical bans on constitutionally protected firearms and magazines. Alongside our friends at CSSA and the FPC Grassroots Army, we’re proud to Fight Forward for all Coloradans and everyone who visits the Centennial State.” — FPC President Brandon Combs
“Denver’s ‘assault weapons’ ban and Colorado’s magazine restrictions don’t make anyone safer — they just turn law-abiding citizens into criminals for owning some of the most common firearms and components in America. The Colorado State Shooting Association is proud to stand alongside the Firearms Policy Coalition in challenging these unconstitutional laws, and it’s no coincidence the DOJ is challenging the same policies. The writing is on the wall for lawmakers who’ve ignored the Second Amendment for too long.” — Kolby Zipperer, Vice President, CSSA
