Oh man... If anything I've simply noticed that its a LOT harder to hit people with revolvers now. If that hit box is anything like the screenshot that would make sense as well.
Not sure if I'm even gonna keep up this endeavor. Shotguns are just way too effective at pretty much any range and I don't like to back peddle.
Thanks anyways for the advice, I see there's a reason no one uses anything but a shotgun now haha
