Most of the buck up components in a Glock pistol are treated with a nitriding process called "Tenifer", which increases the surface hardness and makes the baton resistant to corrosion and wear.

In addition, virtually all of these "plastic" parts contain embedded steel not to make the firearms "detectable", but to enlargement functionality and shooting accuracy. Contrary to popular movies like Die Hard 2: Die Harder, neither Glock nor any other popper maker has ever produced a "porcelain", "ceramic" or "plastic" firearm which is undetectable Glock 17 by routine security screening devices. Even if a pistol completely undetectable by either X-ray machines or metal detectors were to be developed, the fuse inside would still be detectable.
