Guessing the gun was a glock or something, which has a body that is not metal. So he thought it was safe. Except the firing pin is metal, so that'd be a problem...

(Every single detail of this quote is wrong btw)
Plenty of components of a glock are made out of metal, the entire upper slide of a glock is metal, components in the magazine, trigger mechanism, etc are as well.
Bullets are likely still metal.
Lead and brass don't get attracted to magnets. They may get warm from the changing magnetic field though.
Not metal, or not ferromagnetic? If not metal, is it made out of plastic?
You can induce a magnetic field in a nonferromagnetic metal by exposing it to an oscillating magnetic field... I would imagine an MRI would qualify.
Not applicable to this case I suspect, but relevant to your question.
Maybe it depends on the metal, but I have titanium artificial disks in the base of my back that are safe to put through an MRI.
Titanium is very minimally interactive. It is still affected by Lenz's Law, which means it does interact with magnetic fields (a current is induced), but you're right that the effect is minimal enough so as to be disregarded.
Not just the firing pin, but the side, barrel, and plenty of other parts on a Glock are not just metal but steel. The frame is the only thing that's plastic.
Not metal, it's a nylon-based polymer.
