New here , just got my first luger

Straw is a yellowish heat treating process that should be on your trigger, safety lever, etc. Not bluing. So someone has already finished at least those small parts.
It will hold up just fine without being restored. Just keep it cleaned and lightly oiled. It is a nice shooter and we just hate to see you throw money away. For the price of a good restoration you will get pretty close to a matching war gun if you look hard. Then you can have a shooter AND a collectable.
Do your research on this site and be patient before making a restoration decision. I think that down the road you will be glad you did.
