DENVER — Colorado's Democratic-controlled House has narrowly passed a handful of gun control bills, signaling a political shift in the wake of recent mass shootings and pressure from the White House.

"Enough is enough. I'm sick and tired of bloodshed," said Democratic Rep. Rhonda Fields, who sponsored a bill limiting the size of ammunition magazines. Fields, whose son was fatally shot in 2005, represents the district where a gunman opened fire at a suburban Denver movie theater last summer.

The bill was among four that the legislative chamber passed Monday amid strong resistance from Republicans, who were joined by a few Democrats. The ammunition restrictions measure passed 34-31 after three Democrats joined all Republicans voting no.
