The high bore axis thing is overdone. Obviously we are talking about incremental distances first off. Next yes all things being equal a lower bore axis transfers recoil more straight back into the shooters hand. But how the gun fits the persons hand (or not), the weight of the gun, the strength and experience of the person shooting ,the guns caliber, and many other things effect how well a person handles recoil.
Hell stick with just Glocks. My G30 was made when they first came out. It is a fat boy no doubt. But the increased surface area in the grip actully seems to spread the recoil over my hand much better than the single stack G36. And the G30S with it's slightly lighter weight, thus increased slide velocity seems much less pleasant to shoot than my old G30. A person with a different hand size may have a different experience.
Years ago one of the gunwriters actually shot a SIG 228 vs. a G19 to see the differences in recoil and how it would effect split times. He had carried the 228 for many years as his duty gun. Then later his agency switched over to the G19. He had about equal experience with both guns. It was a wash. Their were no differences to speak of between split times of shots of the same ammo with each gun. Too many people are looking at only one aspect of recoil control. Bore axis is only one small component of it. Grip material, and how course the insh treatment is even effect the equation.
As long as the gun fits your hand, is not a 500 Magnum which is so powerful your going to get hugh recoil anyway you go, you use good technique, and so on. The differences between how fast you get back on target with two guns of the same caliber, with the same ammo, but slightly different bore heights (and we are talking slight) their just won't be enough difference for most people between split times to even matter.
