I SAW the results of ridiculously poor machine work. "Some" few of the guns sold worked moderately well.
They actually were not that complicated, just different. They have much fewer parts than a hammer CZ, especially small pins, springs and small parts. Cutting sight dovetails, machining "round" bbl chambers and mounting triggers that don't move side-side and pull smoothly "before even being attached to the action" is not rocket science complicated.
Whatever, it appears Pedersen's basic design is more than our computer enhanced machine capability can handle.
