IIRC, it was a spline connection, and sometimes the spline would let go, allowing the handle to slip. The spot-weld was to prevent that. Could have been more than one method used too.
I think I’ll call just to satisfy my curiosity.
I believe they had a silver washer put in and the part heated so the washer would melt into the joint. I had one that had to go back to browning to fix that issue. It was NIB, when it was purchased and Browning fixed at NC.
