It's fake. The ejection port on handguns is on the right side. There would have been spent casings bouncing off the window. There were no casings flying out of the gun at all. It wasn't being fired.

Plus, there were 22-23 flashes, and there are magazines that hold 20-30 rounds, but they extend below the handle/frame of the gun. The magazine was flush with the handle.

Another way you know it's fake is he didn't really pull back the slide. He could have had one in the chamber, but then why pretend to pull back the slide?

Yet another way it's fake is, he was holding that gun maybe 12 inches from his ears on the other side of a single pane of glass without his arms extended without earpro. Have you ever fired a handgun 12 inches from your ears? You don't fire more than one round unless your life is in danger because it's way past the threshold of pain at that distance. There's no fucking way he fired off 23 rounds a foot from his head. He would have permanent hearing loss.

I counted 22 flashes, +/- 3 for margin of error.

At least heyear in Commiefornia, wheryear only aloud ten bullets per poppin awf.
