British police say they have seized components of a gun made from plastic on a 3-D printer.
The Greater Manchester Police force says a plastic magazine and trigger were seized along with a 3-D printer in a raid against suspected gang members.
The parts are being tested to see whether the gun would have worked.
Police said Friday that if the gun were viable it would be the first such seizure in Britain.
Earlier this year a Texas company said it had successfully test-fired a handgun created with a 3-D printer. Such printers can be paired with a home computer to manufacture objects using layers of high-density plastic.
Authorities worry the technology could allow anyone to manufacture guns which would pass unnoticed through metal detectors.
