When you eventually get around to buying into airsoft, just get a CM16......a lot of the 'speciality' WWII guns are shite. The Stens, M3 Grease Guns and Thompsons are your best bet for starting WWII airsoft when you get around to it.
Not actually a Luger, but it's kind of got that look, is the KJ Works Mk1 'Ruger'. It may be a bit hot for some sites with light BBs, but it's an excellent and simple GBB pistol and only costs about 40 quid too.
