I was told by another gun manufacturer that the serial number must be put on as soon as the frame can be made into a functioning gun. So what ever the last machining operation is I would guess it would happen after that. This also helps to not have serial numbers lost in production by errors or accidents. I was told that its very bad to have gaps in serial numbers.
Also manufacturers arent big on waste, so if a part has a problem it might get put to the side and fixed later, then get finished.
