Check the early westerns and such and the guy will seize up and tip over, and that's it. These days they will take flight, either over a bar, table or out a window, from a standstill.
Never mind that they love going over the top with sound effects.
A gun shot is not that much different from a firecracker, and a punch is near silent...
Also gunshots are loud enough to require hearing protection at a shooting range, and a punch is also audible, but just higher pitch.
What was your point in posting this?
As for point, its that Hollywood have given a ever flashier and exaggerated presentation of the effects of guns.
Agreed but there are also many exceptions to this especially in the military genre (Hacksaw Ridge being the latest example).
What? No. Guns are loud.
