I think I understand what you're saying, but it's exactly those contortions which seem so unnatural to me -- and which I am unlikely to remember to do when I'm in a hurry.Shift your right thumb. Instead of resting it on the gun, rest it on the back of the base of the left thumb. That’s what I do, due to my long fingers. Doesn’t effect my grip, but gets my thumb away from the slide release.
Grip with your right hand, but stick the thumb up and out of the way, not touching the frame. Sock the left hand up in the gap, high and tight. Rest the right thumb on the base of the left thumb. This will leave a “pocket” where the slide release is at, with nothing touching it.
As an added bonus, this will get the left hand a bit higher up on the gun for added recoil control and recovery.
This is the grip that I teach my students, as well.
