The 45 ACP has much more case volume and can be loaded to make 500 fps easier than the 40sw can. For example a 165 grain .40sw at 1100 fps is a good warm load and will give you 443 foot pounds while a +p 45 acp load with a 165 grain bullet at 1250 will give you 572 foot pounds. Neither are great hunting handgun choices but if I had to pick I would take the .45 acp with warm handloads in a gun that could handle it.
However you need to check your laws. My State has no such laws and I don't think they are common but you do need to know your states laws.
