I think you’re probably wrong on both counts, but apparently it’ll be a while so who knows for sure.
1. The current (now prior) version had German slide, USA frame (Ft. Smith, Arkansas).
1a. Walther recently began expansion of its Ft. Smith facility. This suggests all USA manufacture to avoid tariffs and control end cost.
2. It would really be a serious re-engineering feat to reconfigure that small thing to a Browning action vs. blowback. Doing that and handling 9x19, wow. Hope you’re right though!
That wouldn't likely point to a multi-year full suspension of manufacturing as they're doing here.
There are a lot of individuals who want to concealed carry with a PPK but want something with more power. If it could be reengineered for 9mm Parabellum, it might become a top seller.
