My friend has NP22. I do not know how old it is. I was looking at it yesterday and the frame looks like it was just painted with black paint. Slide has a different finish. I find it difficult to describe, but it is not paint, it almost looks like it is powder coated. Otherwise, inside it looks pretty similar to the Sig 226 that I used to own. He has Hogue grips on it and the gun sits very comfortable in the hand.
