I see your problem now. Fingers crossed that one of the springs you have been offered solves it.
Don't be tempted to cut off a full coil again, if necessary you can slowly grind them down on a grinder, or even a Dremel, and also get a nice smooth surface as a result.
I wonder with all this talk about extractor and ejector, if perhaps you may have had the wrong spring supplied.
Also, on the 595 you have an extractor claw which acts on a pivot pin and is pushed by a coil spring, from memory the extractor claw is very similar, but slightly thinner, than the Sako equivalent ( they can be mixed up) .
This may be your issue.
