The contentious legislative battle over guns in the Colorado legislature has not yet translated yet into lobbying dollars.

The National Rifle Association, which opposes all four bills voted on Monday, reported only $2,423 in lobbying costs for January, according to the Colorado Secretary of State’s Office. Rocky Mountain Gun Owners reported it has spent nothing.

Early disclosures, however, may not be indicative of money to come. Mayors Against Illegal Guns, founded by New York City Mayor Michael Bloomberg, spent $4,000 supporting both restrictions on high-capacity magazines and background checks for gun transfers. But Will Coyne, co-founder of Headwater Strategies, said his firm has a $25,000 lobbying agreement with the mayor’s group and has not been paid yet.

Colorado State University and Colorado Community College System spent money to support the prohibition of concealed-carry on college campuses. Exact totals are impossible to calculate since both organizations paid lobbyists in a lump sum, and the lobbyists are working on multiple bills for them.

Gun control advocate Colorado Ceasefire reported it spent $1,041, and Colorado Association of Chiefs of Police, SAFE Colorado and Colorado Coalition Against Domestic Violence all hired lobbyists to support gun control measures.
