I know a guy who would lrobably buy it just because it is not stainless. He used to,quip that: "Real men shoot blued steel guns". I am guessing that being Parkerized would not make much difference to him but he did not like stainless.
That's funny, I don't see the logic in that personally. I own a few Steel coated pistols, but when I carry them they rust, and quickly. Spending a little time outdoors with a brand new pistol and coming home to a new orange iron oxide finish I didn't pay for makes me furious. Normal wear and tear will happen, but I HATE rust.
