Swiss 9mm lugers are an interesting, and difficult bunch. By the time that the Bern arsenal was done bumming around and finally got a working prototype that produced acceptable results accuracy wise, the army already had decided to go with the P210 design instead.
Tinkering with the opening curve, using wrong steel types and generally thinking they were smarter than the Germans meant that the Swiss 9mm was an utter failure.
Swiss gun engineering knowledge is often overrated, as are most of their products
