Here is the reply from Belt Mt.
"When a new larger pin is installed, this can speed up the timing. It
sounds like the cylinder latch isn't disengaging fast enough before the
pawl starts to move the cylinder. I would take 2 strokes off the top edge
of the pawl and see if the extra clearance cures this problem. Call me if
you need to, afternoons and evenings are the best time.

Driftwood, this is just the plain Colt Style pin.
