That's where the 7.3 oz more for the MK 40 might help ease the recoil pain. My early experiences with nasty recoil started with 6" barreled SA revolvers so a light weight .40 pistol probably wouldn't bother me too much. I presently own a Charter Arms .44 Bulldog which has a pretty stiff recoil as it parallels some of the .45 ACP loads. What I figure is that in a firefight situation with adrenalin flowing at max it's doubtful recoil will be much of an issue.
