Kept hearing that the .40 S&W is just too snappy, but I'd never really noticed much difference between it and my 9mm pistols. Of course, I wasn't looking for it and am not all that recoil sensitive, yet. Another thing to look forward to as we age is our hands starting to get a bit worn out and become sensitive to things like increases in recoil.
So I made a video with three different Glocks to see how much each pistol jumped.
What do you know? The .40 S&W is a bit snappier than the 9mm...
Go to around the 8:00 mark to avoid all my blathering about not being an expert and my background.
