Yup looked it up and you are right on that SIG being a subcontractor, it was the same with the K31's.
Accuracy was more important to the Swiss as stopping power, don't forget that they did shoot competions at 50 meters that is why a new 9mm pistol that is less accurate as the former one was hard to introduce there.
That was also the reason that 210's were approved at official matches in as well 7.65 as 9mm, many had an extra barrel and spring that they used with their service pistols.
I think most of the W+F archives to be in the Bundes-archive at Berne and with RUAG now.
Glad to see this section back alive again, it has been silent here for too long.
