Sounds good.
Take it to a gunsmith and show him the barrel ammo fit. See what he says.
Have the gunsmith check the headspace with a gauge. You'll need to find one who's a decent machinist or has 9mm gauges.
Actually the hs may be ok but the throat may be short or tight. If so there will be markings on the bullet.
Support your local gunsmith.
Some of them may actually know what they are doing,
