It's interesting to see politicians lash out against what is essentially a zip gun. Maybe the US government should focus on making sure people don't feel the need to bring guns to "secure" locations?Security checkpoints, background checks, and gun regulations will do little good if criminals can print plastic firearms at home and bring those firearms through metal detectors with no one the wiser
You have forgotten the freak-fest that was the Glock 17's release. The Undetectable Firearms Act mentioned in the article arose from 60 Minutes getting jaw-droppingly stupid over the fact that the 17 had a plastic housing - therefore would somehow be "undetectable in airports" (never mind the metal barrel, receiver, magazine, action, etc). Most people don't understand firearms and don't really understand that barrels that lack the density to trip a metal detector or x-ray also lack the rigidity or thermal performance to be much more than bullet holders. ...and bullets trip metal detectors just fine.
