Don't you still need metal bullets for the 3d printed gun?

Those don't generally have any ferrous components.

  • yes but the spring in the magazine does.

    also the rails on the lower, the barrel, etc.

    • If you want a gun you can use more than a couple times need metals. However if the goal is one shot plastic is good enough. Even plastic bullets will work - not well, but one well placed/timed shot is all we are talking about.

    • Not in the context of someone smuggling a weapon through a security checkpoint. At least not unless they're certain that it's small enough not to trigger the detector.

      That said I will note that it is generally illegal to possess such nonferrous weapons regardless of circumstance.

No idea. I only replied to the guy saying that "metal detectors stop weapons". Which is false.

The evidence is in US law. Because they would be undetectable, 3d printed guns are required to have some metal inserted into it to be legal (https://en.wikipedia.org/wiki/3D-printed_firearm#United_Stat...). I think a guy who can 3d print a gun and wants to bring it onto a plane could probably skip that step;)

  • > The evidence is in US law.

    Laws written by people utterly ignorant of the subject they're legislating is not evidence of anything.

  • "I only replied to the guy saying that "metal detectors stop weapons". Which is false."

    Taken in a strict boolean sense, yes, but real-world policy is rarely boolean, and mostly about tradeoffs and how many nines of reliability you want to spend on.

    Metal detectors will catch the vast, vast majority of guns ever produced, which is their whole point of existence.
