Okay, I too am a student of the Parker. Here's my understanding of "off face". Subject to correction of course.
Open the gun and look at the frame where the two holes show for the firing pins to pass through. That surface is the "face".
Close the barrels. If it closes tight with no detectable movement and no measurable clearance between the barrels and frame face, it is "on face"
Any movement or measurable gap would be "off face"
common cause
Barrel lug that mates with the hinge pin is worn
Permanent fix: weld the lug mating surface and file/dress to fit
Decent fix: rolled brass shim over hinge pin You can make a shim from the appropriate size brass feeler gauge
That would be my response if I were writing the test.
