Depending on the ammunition type, those guns all stand out as having very low penetration. Starting with the handgun, the two most popular calibers are 9 mm and .45, and if you shoot hollow point rounds, they can even be stopped by a few inches of drywall (hollow points are designed to expand on contact), and lead bullets may also be stopped by the truck if they are shot at an angle, but I wouldn't be sure about high-penetration rounds like full metal jacket. The Tommy gun is also handgun-caliber (assuming they shelled outout a small fortune to rent a real one, .45). Shotguns have an even wider variety of available projectiles. A shotgun shooting buckshot has far lower kinetic energy behind each projectile than a handgun, and their velocity falls off very quickly with increased range. A slug (a solid chunk of metal) designed for armor penetration, on the other hand, will penetrate 3 mm of steel easily, with similar caveats about range.

Just replying to myself because I watched the video: the Tommy gun was loaded with hollow points, the pistol was a 9 mm Glock and shooting regular lead bullets and one of them penetrated, and the shotgun was 00 buckshot, and even the buckshot had a penetration. Their excuse for both penetrations was "two hit right in the same spot," but that is pretty doubtful. They also used a suppressed MP5 in the mix, which would have lower velocity (and thus less penetration) than the pistol, and shot the same ammunition as the pistol. All in all, a very unimpressive trial.

  Suppressors don’t have a significant effect on muzzle velocity [0]. That said, in my experience, most people who shoot suppressed intentionally shoot subsonic rounds, since they are inherently quieter. If anyone in Arizona gets a Cybertruck and is interested in more testing, I own a (legal) machine gun and I would be honored to test your vehicle’s bulletproofing. I’ll even supply the ammo.
