Back to the range today.
One failure to close the toggle and one failure to extract.
Came home, pulled the barrel and did a proper polish on the chamber.
Also re-shaped the extractor hook a bit.
Next time, maybe the tweaks will take care of the last of the problems!
Just a side note, the barrel was really tight, all the way off with the wrench. Must have been a bear to put in. Way too tight, I suspect the Finn barrel threads were not cut quite deep enough, I chased them on the lathe and though still tight, it screwed back into the receiver much easier.
I may not shoot it again after these first attempts, but I just won't keep a pistol that does not function and fire as it should. One never knows when they will need one.
The way it was left from re-build, it was likely to get a Finn soldier killed if he "needed" it to use!
