DENVER (AP) - Most of Colorado's elected sheriffs are trying to strike new gun restrictions with a federal lawsuit against the state that argues the laws violate the right to bear arms.
The laws passed this spring limit the size of ammunition magazines and expand background checks to private and online firearm sales.
The lawsuit was filed Friday.
The majority of sheriffs involved in the lawsuit represent rural, gun-friendly areas of the state.
They argue the laws set to take effect July 1 have many flaws that will make it nearly impossible for citizens to comply with and they insist the measures won't improve public safety.
The measures were a response to mass shootings in Colorado and Connecticut last year.
Victims' relatives accused the sheriffs of playing politics.
