Here is a link to my pictures of it. Hopefully they are acceptable looking. I can't tell if it was parkerized or blued. It does have the plastic grips and I have one metal bottom and one plastic bottomed mag. The Luger was passed down to me from my grandfather. He always told me it was a bring back from WW2. He had some other German items that went with it but my dad has all that stuff. It kinda surprised me when you said it was a Portuguese contract when he told me he brought it back himself. He passed away 3 weeks ago unfortunately so I couldn't ask him to clarify now unfortunately. Would you mind sending me some more info on the Portuguese contract guns?
