Looks like I spoke too soon. I thought I had gotten lucky and CZ didn't have a pocket of air in the casting.
Nope! It's in the exact same place as all the others I've done.
This is why I hesitate to round off a stainless CZ frame. Not sure I want to test out matching the finish on stainless filler.
I shoe shined the trigger guard today and it was perfect... All except for this one place that just wouldn't polish up right.
So I took my fingernail and pushed into it. Yep. Cavity. I pushed harder. It went deeper.
So I pushed on it with a punch to see how deep it went and dremeled it out. It looks pretty deep.
Not sure of my welding approach on this one. I may lay some filler metal in the channel created by the dremel bit and the try and create a speed bump with it.
I also noticed a very tiny pinhole. I'm going to ignore it.
