this is not glock buldge busting so to speak, this is brass base swaging.
Look up saami specs, that will give your answer.
I did look up the SAAMI specs, as I posted just above your response. Where else would I have gotten my numbers?

The largest OD for the 9mm Luger (which is at the head end, where bulge removal may be needed) is .3910".
For the 9x18 Makarov, the case OD at the mouth is .3902" and at the head it's .3915".
