As I can't find any, new or old, reasonably priced.. I think my fist offering will be the just slightly taller standard unit... and in my own experiences, I've found a need for the .250" offering... after that, it gets a bit iffy? Meaning it is hard to maintain the Luger profile and still have a tall blade...Profile lines don't line up very well on the tall sights....
... I'm thinking .300" is about max within the original design parameters? That is why I'm asking? Do taller blades exist? What did the Germans do?...
.... Not a lot of info out there... best to all, til....lat'r....GT
