Title doesn't (really) reflect that this was part of a test, and not that someone was found to have smuggled a 3D printed weapon in.

Also, the article does not mention whether or not ammunition was smuggled as well; I'd imagine that'd be harder to hide from a metal detector than plastic -- and the gun isn't much good without bullets.

Correct. The article says that the plastic pistol was brought within yards of the Prime Minister by a correspondent from a show on Israel's News 10. It says that the Israel Security Agency (sometimes known in English as "Shin Bet") characterized this act as irresponsible. It says that the weapon was tested by firing at a cardboard target.

Curiously enough, they don't exactly say they hit the target - they say they fired "towards" the target (I've read the Hebrew original of course), but it doesn't mean they actually hit it. I imagine the accuracy of such device would be pretty bad...
