Firing update - without the stock attached".
Not so hot, some failures to feed and failures to extract. So back home to trouble shoot and see what is up.
As I said, pistol is essentially "new" since rebuild, I noticed:
1-chamber rough, leaving marks on brass- probably cause of extraction failures-
- action; polish chamber, clean extractor recess, change extractor spring to a stronger one
2-chamber edge and ramp, pretty "steep"- maybe part of FTF problem
-action: break edges, give ramp a little more slope, polish ramp
3-Toggle opening force hard, very "stiff "and hard to charge - maybe related to feed issues
-action: check recoil spring and change to standard spring;
3a-Toggle stiff-check toggle movement-rear toggle knee action very stiff at near full recoil-
indicating binding due to insufficient clearance
-action: disassemble, file, sand, polish to gain clearance between mid link "eye" and rear
toggle slot, re-assemble and lube. Made a big difference in movement and perceived force needed to charge!
Next week - back to the range for results and a follow up report to be posted.
Based on this one example, I would say the Finnish armorers were not nearly as careful as the DWM workers when building/repairing a luger; but then they did work for the "government".
