Larimer County Sheriff Justin Smith, joined by other sheriffs from around the state, speaks to a crowd Wednesday, April 3, 2013 in Denver. The sheriffs are slamming new regulations Gov. John Hickenlooper recently signed into law as unconstitutional.

DENVER — More than half of Colorado sheriffs are considering a legal challenge to the state's recently passed gun restrictions.

According to the Denver Post, 37 of the state's 62 elected sheriffs are prepared to sue in an effort to overturn laws that now prohibit the sale of ammunition magazines holding more than 15 rounds and require background checks for all private gun sales.

Weld County Sheriff John Cooke said Tuesday some sheriffs oppose legal action, and an association that lobbies for sheriffs has decided not to take part.
