Ridiculously inaccurate depictions of guns are an old staple of Hollywood at this point. Impossibly quiet is a common one. I always remember that scene in Glory when Matthew Broderick is firing a pistol inches away from both his and another soldier's ear. Great scene, but their eardrums would be blown the fuck out irl. Then there are six-shooters and even single-shot firearms that just keep shooting. And of course the most common, the villains who never hit their targets while the heroes never miss unless the plot needs them too. This one is especially absurd when the villains have rifles while the heroes have pistols.
