gmlasam, AFAIK, there is no other way to gain access to the inside of the handle other than removing the butt cap or the trap door in the butt cap. There are a few that have a small trap door in them that can be opened without removing the entire cap. One has to examine the cap carefully to tell if it has such a door in it. I know some of the Wilson's did, but none of the Prince frames do, AFAIK.
