As a result, every shot would result in muzzle flip no matter how much of a death grip I had. Even with grip tape, the friction eventually rubs the texture off or moved the tape all over the frame.
The left grip seems to be more efficient for guns with smoother frames as it allows you to cover more of the grip. But that’s to be determined next time.
(Ironically, the photo is presented as “before and after” learning “proper gripping technique”)

I've had more success, comfort, consistency with my right thumb lifted up and away fromthe frame and off my support hand, otherwise i think i push down on my support hand helping to cause it to slip. i hook my support index finger over my firing hand's middle finger. i try to do most of my gripping and aiming with my support hand, the firing hands only job is to move the trigger without upsetting anything else. at least that's what i try to do following ben stoeger's instruction. he's got videos of his classes on his youtube.
for pistols with big thumb safeties like some 1911s and CZs, i'll rest the firing hand thumb on that, but i think doing too much with either thumb upsets a consistent clean trigger pull and repeatable up and down muzzle flip.
everyone's got different hands and different guns, it's good to try different things out and see what works for you
