Dam TRH if a 40 S&W recoil is a problem for you to hold on to, I suggest a better diet and strength and conditioning program ASAP
It's a matter of noticing the difference between the level of effort necessary to keep the support hand firmly in place while shooting the Glock 22 vs that for the Glock 17. Do you find that zero effort is required for both? If so, that's wonderful for you. The Justice League is looking for new members.
PS I notice no difference in this regard as between my Glock 30 (.45 ACP) and my Glock 17. The 30 requires no more concentration to keep the two-handed grip firmly together through the recoil impulse than does the 17. There's something about the .40 S&W, that many call "snappiness," that makes the difference in this regard. While the Glock 30 has at least as much force in its recoil impulse, it's not as "snappy."
