A Colorado bill banning the manufacture and sale of semiautomatic guns with detachable magazines advanced through its first committee hearing after an eight-hour session on Tuesday.
Senate Bill 3, sponsored by Democratic Sen. Tom Sullivan, advanced 3-2 along party lines in the Senate State, Military, and Veterans Affairs Committee.
Supporters argue that the measure will enforce existing magazine capacity limits and reduce mass shooting damage.
Opponents, including Rocky Mountain Gun Owners and several county sheriffs, argue that it infringes on constitutional rights and have pledged to mount legal challenges. The bill now heads to the full Senate.
