Did I hear something a long time ago that there was a new P3AT extractor and screw available?
I swear I used the right size wrench trying to get that screw off and it just stripped the head out. I can probably get it out but I dont think it will go back in.
Call KT for a new screw or two, then use a cutting wheel on a dremel and cut a slot in the old screw for a flat-head screwdriver and remove it that way. When installing the new screw, use a drop of blue locktite on the upper threads.
