Corrected entry: When Ness chases Nitti onto the roof of the courthouse, Nitti turns to fire back at him. He fires his .45 empty - we can see that the slide is back and the barrel is protruding - then runs a bit more, then turns to fire again. Anyone who knows anything about guns - like, say, a professional killer - would know when an automatic is empty.

Correction: He's a professional killer, yes, but that doesn't mean he wouldn't try to fire without checking the gun to see if the slide was back. Military personnel who handle firearms for a living have been known to do similar things in real life.
