Hk45c Barrel vs P2000sk 9mm Barrel Bores marks

[davebee456]

I have a barrel question about the rifling of these two pistols..

I have them both and after cleaning and inspecting both barrels
bores ,
I see that the p2000sk 9mm has a more of a glass polish inside with no lines or marks.

the hk45c has less of that glass finish inside, almost looks like fine scratches along the rifling.
I prey that they aren't scratches but just machine marks perhaps..

Has anyone noticed this in comparing 45acp Hk barrels to 9mm barrels??

They both have the same amount of rounds through them..about 200 rounds.

Thanks in advance for any help..
