U.S. Senator Brian Schatz wants his colleagues to pass a 10-year ban on undetectable firearms, “including plastic and 3-D printed guns, which do not show up on x-ray machines or through metal detectors,” according to a press release.

The current ban is set to expire this Monday. The House of Representatives passed a ban on undetectable firearms last week on voice vote, and the Senate expects to take up the measure Monday. But the measure, introduced by Rep. Howard Coble (R-N.C.), is just a straight extension of existing law, originally passed in 1988 and later extended.

Schatz is a co-sponsor of the Undetectable Firearms Modernization Actwhich was introduced in April. According to Schatz’s office, he and other Democrats will try to amend the House extension bill to include more safety measures.
