"" Contrary to popular movies like Die Hard 2: Die Harder neither Glock nor any other gun maker has ever produced a "ceramic" or "plastic" firearm which is undetectable by ordinary security screening devices.
In Die Hard 2, the character John McClane portrayed by Bruce Willis specifically referred to a non-existent Glock 7 with many fictitious characteristics:
That punk pulled a Glock 7 on me! You know what that is? It's a porcelain gun made in Germany. It doesn't show up on your airport X-ray machines, and it costs more than you make here in a month!
Furthermore, if a pistol completely undetectable by either X-ray machines or metal detectors were to be developed, the ammunition inside would still be detectable.
Mike Papac, an armorer at Cinema Weaponry, which supplied the Glock pistols used in Die Hard 2, has stated,
"I remember when we did that scene, I tried to talk them out of it. There's no such thing as a gun invisible to metal detectors, and there shouldn't be, but they wouldn't budge. They had it written into the script and that was that.". "" [http://guns.wikia.com/wiki/Glock]
Ansonsten zitiere ich zu dem Thema mal ne andere Seite.:
"Ja, auf den Geräten mit denen das Gepäck durchleuchtet wird erkennst du so gut wie alles! solange es die form einer waffe hat kann es auch aus käse geschnitzt sein!"
sobald du die waffe aber am man[n] trägst sieht es anders aus, da man meißt nur durch einfache metalldetektoren muß!"
=> Ein Keramikmesser wäre auch durch die Kontrollen schmuggelbar.
Keramik-Pistolen hingegen gibt es schlichtweg nicht.
