Since a lot of "helpful" charts have been posted, it's about time someone mentioned all those posted-except those by RobzGuns-are old charts from when handguns were fired by folks standing in a dueling stance and only using one hand. They've got rather limited application for folks using both hands on the gun.

I must say I like the top chart Robzguns posted.

BTW, since I mentioned using both hands on the gun, you are supposed to be using isometric tension while doing that. Push out with the gun hand, pull back with the support hand. Or, at least pull back with the support hand, resist with the gun hand.
