I agree with Don. Something more like a short lug layered cannon breech lock would have been much more robust:



A slightly shorter striker with a thicker multi-lug support in the spring guide would have been a better design. Alas, we were not in the design meetings with Georg...

The ejector spring must have been complex to manufacture. We know that it was hardened prior to strawing. I wonder if the forward triangular ejector tab and mount were extruded from a single stock piece of metal?
