Rocky,
Read somewhere where someone had developed an accurizer pin that was adjustable for that problem.
Don't know the validity of it all, as it was sometime ago, but it sounded feasible at the time.
I know adding adjustible features only drives the price up on an already expensive item, but, you'd think that they could make some type of system that would allow variations from wear and/or tolerances to be remedied.
I've machined new pins on frames that were sloppy, and thought that a "T" pin that was flanged and permanent at one end, with the same design on the opposite side, only threaded into the pin, would work very well. Recessing the frame on both sides would work bettter and allow it to fit beneath the stocks.
Also, making a pin, or bolt, that threaded into the frame on one side, with a larger head on the other, would place it under tension, and only allow the barrel to rotate on the shaft of the pin.
Making these in various shaft diameter's, (or added shims) probably, would aid those with tolerance problems.
Just thoughts I guess........I guess I need an old frame to practice on
