The House of Representatives voted Tuesday to extend a ban on undetectable plastic guns, but Sen. Chuck Schumer says more needs to be done.
3-D printing is making it easier to acquire plastic guns that do not set off X-ray or metal detectors.
The House's vote is a step toward extending an already-existing ban another 10 years, but Schumer said that they failed to close a major loophole.
"The present ban, when it was written in 1988, no one thought that anyone would actually be able to produce these guns, said it would be OK to have a removable piece of metal on the gun," Schumer said. "Now, that's very dangerous, because if you can remove the metal at the last minute, put the gun through the metal detector, it'll get through and could create mayhem."
Schumer said that the Senate will try to pass a bill next week that closes the loophole.
