And it doesn't strike you that maybe two types of guns with vastly different ergonomics might benefit from different grips?
I'm not saying what you do doesn't work 'well enough' for you, just that it may not be optimal for everyone.
I'm not recommending anything for "everyone", I'm saying that once you leave the range there's a few more things to consider than "thumbs high" for speed. What works for 9mmepiphany doesn't work for me, that's okay. I've been shooting handguns for about 40years, I was taught by my father, a military firearms instructor. In his world, and mine, that gun is useless if you can't shoot it with one hand (either one) and you can't hang on to it, and when it's empty and the SHTF it's a very efficient blunt object if you've got the grip to use it as such.
As far as ergonomics and platforms - a gun is a gun is a gun - you need to be able to pick up whatever is there and fight with it. I don't see the point in having different methods for one platform vs the other, never needed them. I use the same basic stance/positioning/grip for interview, H2H, pistol, revolver, rifle/shotgun, never have to think about where I am or what I'm doing.
As far as the OP's question goes, I've never had any issues with recoil using what I've been taught and what I've practiced for all of these years regardless of caliber or platform.
