This was good, I learned something.
The first pic, is my strong hand hold. Both thumbs forward. My grip is as high as possible, thus I have the most control of the gun as possible( the most amount of the gun is in the grasp as possible) , and the least amount of felt recoil as well.
The second pic is my weak hand hold. Very little experience, thus I feel more comfortable with the thumb holding the other thumb down hold. You can see that the grip is a lower grip style. While more comfortable, it does not appear to have as much control of the gun since it does not have as much of the gun in the grasp.
I can see that I need to practice a different uncomfortable grip for my weak grasp for more control. With more practice it will become comfortable.
