Great idea and material for a handgun thread.
I have spent over 30 Greyears instructing with handguns and the grip is the first and the most critical item to enforce to the student. (after or with all safety items of course) I have helped more people correct their accuracy problems by just slight changes in their grip than perhaps any other bad habit that I have seen in my career.
I recently used this example to show that if your grip is correct, it will not matter the size of your mitts or the frame size of the gun you pick up, it will simply work.
Here are some pictures I recently sent to a young fellow and he has since written to tell me how it has improved his shooting overall and that he is especially happy with his follow-up shots.
I did this primarily to show the proper grip for the 1911, but I also wanted to show how well the primary grip works with all handguns.
