A handgun made of ceramics to disguise from metal detectors 🤔

They work. The Gov. made some about 30yrs. ago. They're two shot derringers chambered for .38 special. They also made some ceramic and polymer semi-auto 9mm Glock copies.

Yes, these absolutely work.

Very worryingly, yes. The material is a special form of ceramic, not bone-china.

Most modern weapons are mostly plastic and some ceramics. As of right now though there is no getting around a metal barrel though.

Yes, they do work but they're not actually made from ceramics... they're made from a very hard plastic composite and are made with a 3D printer. That includes the bullets which are non-traceable as well as the shell casings and includes everything except the gun powder that goes inside which you'd have to install yourself.
