I was reading through the Glock Annual '10 magazine and noticed that some shooters were gripping their Glocks differently than I do. Page 32/33 are good examples. They are putting their thumb that is on their trigger hand on top of the thumb of their weak hand. The thumb of my weak hand goes over my trigger hand thumb. My trigger hand thumb rest in the depression of the grip. So, what is your thumb position when you shoot (Glocks) ?
