This is close to asking "How do you sit in the driver's seat?"
Everyone has a variation of their favorite hold. Thumbs up, thumbs on safety, thumbs forward, white knuckled, limp wrist, etc...
If your hold will allow you to shoot 500 rounds in one day (think a 1 day competition) and your hands do not hurt afterwards, then you have developed the hold for you.
If your hand hurts after 10 rounds of .45ACP in the M1911a1, then you are holding it wrong.
