Hi ****, welcome to the forum!
My RIA's have the same "finish" as yours, which isn't much, sort of a thin blue Parkerizing. It's serviceable but not much for looks. The rollmark is about the most anemic I've ever seen, you almost have to get a magnifying glass out to see it. What the guns lack in cosmetics they make up for in shootability and utility.
Mine both came with a rudimentary "manual", I think I spent about a minute looking through it, didn't learn anything I didn't already know, and proceeded to the range to break it in. There were a few early FTF's, (not fully in battery) then it smoothed right out and shot as well as I can with open sights. The sights on the Tactical model are far better for my eyes, and I can shoot that gun better than I did the GI version.
I've entertained the idea of sending the gun off to have it redone in one of the Wonder Finishes, but it would cost almost as much as the gun did, and I bought this one to carry, not admire. I don't worry about scuffing it up, I just feed it good ammo and try to shoot it well. Beauty is as beauty does.
Let us know how you two get along after it's broken in. I usually give a new autopistol between 200-400 rounds to let the working parts wear in, keep it clean, and go from there.
