It's interesting to notice even those salt blued guns, e.g. "Black Widows", Modell 1930s, Schnellfeuers, etc, also have unblued muzzle (Vince, sorry, but it's definitely not by holster rubbing -- rubbing could not do the job so clean and so uniform... and on so many guns).
Mauser Parabellum imported by Interarms in 1970s has blued muzzle. I have never seen a postwar HK Luger..... don't know that one.
