RZ-10 casing marks on slide, first 100 rounds
I?m looking for suggestions for fixing the issue, cleaning the marks off this awesome pistol.

Is this a warranty issue?

I tried normal cleaning methods, I don?t want to do anything to hurt the finishing.

Tried to email CZ, but no response so far. Will call tomorrow if they don?t respond to email.

I shouldn?t be having this issue in the first 100 rounds of a $1,300+ gun.
I don?t expect it to always look new. I understand wear, but this doesn?t seem executable.

I bought a Dan Wesson for quality, perhaps this is a ?one-off?.

Thanks in advance.

Most of my 1911s do that and I've never thought of it as anything other than normal.
