okay after watching that video you linked and rewatching the cam footage i am leaning closer toward it being plausible.. i just don't get why such a gun would be used still! it's basically an antique (and insanely expensive). + modern supressors (paired with an ok pistol) also have the action being pretty much the same volume as the shot. at that close of range, a 22 would have been even more quiet.
