v-w... I have the Handall on my JHP. When I installed it, I looked it up on U-Tube to see how it is done. Its pretty simple with the windex. As a side note, while there is still a "lubricant" under the grip. If possbile shoot a clip through it and you will see the Handall will move to your natural shooting grip position. I did this sort of by accident and like the way it turned out great. Its now a part of my hand when I pickit up....
