Re: h-s length of pull
I have three H-S stocks and have always ordered the standard length of pull which I believe is 13.5". If your factory stocks are working for you, I'd think the standard pull length for the H-S will also. If standard won't work the easiest way to determine your length of pull is to measure the distance from the inside of the elbow to the index finger that is bent to simulate it being on the trigger.
Someday someone may kill you with your own gun, but they should have to beat you to death with it because it is empty.
