I don't think the 40 is less recoil than the 45. There are a lot of factors that go into recoil. The weight of the gun is a big factor, the amount of "pressure" in the barrel and the grain of the bullet and more.
I can't find a good chart. Chuckhawks website has a table, but for 40 it's only showing a light gun weight which makes the recoil look even more. Here's a link to that...
Click...Handgun Recoil Table
This is the best rank order chart I can find...
This shows energy at the muzzle in ft pounds:
45 ACP 411
40 S&W 484
357 magnum 583
44 magnum 1036
I'm pretty sure that's a correct order of recoil for these and from firing most of these myself! I've never fired a 44 magnum though, but I do know the 357 magnum is the biggest recoil handgun I've fired.
Now if you fired a 9mm +P in a light weight small gun and then fired a 45 in a heavy steel 1911, then the felt recoil would be much more on the 9mm +P due to gun weight affecting the momentum of the gun and increased pressure giving more energy out the muzzle.
