I am not real surprised, the 83's have been mostly discontinued for almost 6 years aside from the small run two years ago. We have been lucky to have parts support for even this long especially for such a niche model that was never a huge seller in the US.
I stocked up on parts years ago when I started getting into collecting 83's so I should have enough to keep mine running for a very long time. I feel slightly less insane for the couple hundred dollars of 83 parts I've invested in now that there won't be any more. I mostly only shoot the .32's which should not put much stress on the components of the gun anyway.
Most concerning though is the sear spring - those appear to be out of stock already and that is the part most often damaged during reassembly from a complete detail strip. I am not aware of anywhere else to source the sear springs.
