Why do the guns in Mafia Definitive edition feel so underpowered?

Like half the time I’ll light a dude up with the Thompson and they won’t even flinch. And the revolvers are complete ass. I’ll constantly shoot a dude at point blank range with every bullet in the cylinder and the react like they’re a goddamn Terminator. It’s strange because Mafia 3 has pretty much the same exact shooting controls yet all the enemies feel way more responsive to damage.
