The body panels are pretty thick, and they're made of an austenitic nitrogen steel -- a modified form of 316LN -- which should perform nearly as well as any "armor grade" steel alloy. (Against steel fragments, it likely performs poorly, but against lead handgun rounds it is likely even superior to the average high-hardness armor steel.) Just on the face of it, I'd expect the Cybertruck's body to stop any threat up to .44 Magnum.
Besides, 9mm and .22lr are very different things. .22lr is one of the very weakest ballistic threats. 9mm has much more mass, usually more velocity, and a much higher (~3x higher) average KE load.
Yeah of course I can't find it now, there was some lame Youtuber memelord that let his buddy shoot at it with a handgun and at least one bullet went through. But I also see that it can resist it, so IDK and retract my statement.
I do know the difference between the calibers though, having shot a few different weapons in different calibers (as a hobby & in the military)
Seriously? Is there proof of this?
