I looked at all the spent brass that was sent with it and all looked very nice! No signs of anything including bulges, etc... Anyone have 9x25 fired pre/post measurements on brass?
The barrel looks like it might possibly be Polygonal rifled. Looking for some eyeballs to verify that! With the design of the feed ramp it has a bit more meat underneath versus the 10mm barrel. I would actually call the 9x25 100% support. Does it look like the barrel is crowned at all?

That's a good looking barrel, looks like it has more meat all around unless it's just the sharp edges making it appear that way? Looks like traditional rifling and a shallow crown to me. If you get tired of it let me know!
Will do. I'm sure after a play a while with it and test all the 9x25''s out there I will move on from it.
