I don't know the specifics about who is running PPC but I know that Dennis Willing is the NRA competitions director and from what I have seen he is open to communications. He has 4 Distinguished Badges, 2 are PPC, but I feel that change has to come from the members within the group. If I as a civilian as for change it does not have the same effect as coming from the current shooting group.
If you guys want to see more participation, you have to write him and ask for change. There is only one reason why other action pistol events have increased participation and PPC is dying fast, the people within the group don't want change. The bigger problem is, dying off is a change and that is what they are getting.
