Felt recoil is mostly a function of muzzle energy compared to the weight of the weapon. size and shape of the grip/buttstock is a factor as well as how hard the bolt carrier slams it's backstop.
Chamber pressure is a huge factor in muzzle blast, but not felt recoil.
True, there are a number of different factors that effect the recoil of a gun. All things being equal (including weight of the gun and relationship of the gun's bore axis to the shooter's grip), different calibers seem to recoil differently. Last, there are multiple components to "recoil," including muzzle rise/flip and backward movement of the gun in the shooter's hand.
Having said that, most folks describe the "recoil" of the 40 S&W and 45 ACP as being different. Compared to the 45 ACP, the 40 S&W has more muzzle rise and returns to baseline more slowly. OTOH, the 45 ACP's recoil has more rearward push to it than does the 40 S&W. My experience has been the same. I've always read that the snappier recoil of the 40 S&W is b/c it's rounds are loaded to higher pressure than the 45 ACP, but I can't prove this is the cause.
Here's a video that demonstrates this well. LINK
