DENVER - Ammunition magazine limits and universal background check requirements are set to take effect in Colorado on Monday, even as county sheriffs fight to overturn the new laws in court.
But after months of tense debate among state officials, the signature pieces of Colorado Democrats' gun control legislation are moving from abstract to tangible.
Some gun stores already are stocking smaller magazines to comply with the 15-round limit. And in the coming months, the public will see how the expansion of background checks to private and online sales will work.
As for the sheriffs challenging the law, their next court date is July 10. They are seeking to temporarily block the magazine limit while their lawsuit proceeds.
