WASHINGTON, DC (CBS) - Congress has less than a week to re-authorize the "undetectable firearms act" which requires all guns to have metal pieces in order to make them show up in x-ray machines and metal detectors.
The law has been on the books since 1988 and has been re-authorized unanimously twice before. But now some in Congress say it's out of date and they are proposing changes.
With only a "voice vote", the House passed a resolution re-authorizing the "undetectable firearms act" for ten more years.
Now, the bill heads to the Senate where Democrat Chuck Schumer has argued new technology has made the law outdated.
"Someone in Texas published on the web site a way to make a plastic gun, buying a 3-D printer for less than a thousand dollars," Schumer from New York said.
Under the current law the metal on the plastic gun can be removable and isn't necessary to fire the weapon. Schumer and some others want to change that.
"It is a matter of common sense that we don't want to make it easy for terrorists and criminals to bring guns past metal detectors onto our planes and into security environments," said Rep. Steve Israel of New York.
The NRA says it is okay with re-authorizing the bill as-is. But in a statement says "the NRA strongly opposes any expansion of the undetectable firearms act."
"I believe in, if it works, it's fine. If it ain't broke, don't fix it," said Alex Delgadillo. The California gun dealer says the proposed changes may deter some people but not determined criminals.
"If they want to get a gun into a place that has metal detectors, they'll find a way," said Delgadillo.
