DENVER - As expected, a Republican push to repeal a law limiting high-capacity magazines failed on Monday.
Dozens testified for and against the proposal.
A House committee rejected the bill on a seven to four party-line vote.
The law, passed last year, prohibits the sale of ammunition magazines that hold more than 15 rounds.
Another Republican attempt to repeal the law will be heard in the Senate Wednesday.
Democrats there - also have the votes to stop it.
"There's going to be more mass shootings in America. The question is will people have to wait for a 30 or 50 or 100-round magazine to be unloaded before they have a chance to escape. Or will it be 15? The law we passed last year said 15," Tom Mauser, the father of a Columbine victim said.
But gun rights supporters say this debate needs to stay alive.
"The only people who are negatively affected by this law are those of us who are law-abiding citizens. Criminals do not abide by this. This did not take larger capacity magazines off the street. It left them in our possession and there's no way to tell if that magazine was purchased before or after the law went into effect," saidRep. Chris Holbert (R) Parker.
HB 1151 is one of the shortest pieces of legislation under consideration this year, weighing in at a mere 55 words:
Be it enacted by the General Assembly of the State of Colorado:
SECTION 1. In Colorado Revised Statutes, repeal part 3 of article 12 of title 18.
SECTION 2. Safety clause. The general assembly hereby finds, determines, and declares that this act is necessary for the immediate preservation of the public peace, health, and safety.
(The safety clause is boilerplate language that hastens the enactment of bills.)
The language of that bill is exactly identical to its senate counterpart, SB 100, which is co-sponsored by Sen. Bernie Herpin (R-Colorado Springs,) who took the Senate seat that was vacated when Senate President John Morse was recalled by voters in his district in a special election.
SB 100 will be heard on Wednesday at 1:30 p.m.
Both bills are expected to meet a quick death in the state legislature. Democrats are in control of both chambers, which means they hold a majority on the committees that will hear the bills this week.
The state affairs committee that will hear SB 100, for instance, has already killed a bill that would have repealed the expanded background check law for gun purchases.
Republicans hope that keeping the issue alive could boost their chances of swinging the balance of power in the November elections.
In the meantime, pro-gun activists will continue to work on a legal challenge to gun control in federal court.
