Everyone always said to keep your support hand high up near the slide. I was foolish enough to listen to that when my gun is smooth on the side
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”)
