All my experience has been with making ejectors work properly.
I'm not a fan of ejectors in the field because I keep empty shells for proper disposal. Ejectors often toss them into the tall grass just at a time when you need to keep your eye on the bird, not shells. I do appreciate ejectors on competition guns, where I catch the shells just as they pop out.
Nevertheless, for reasons I can't quite rationalise, I like to keep guns equipped with ejectors as functional ejectors. This has led to a few repair situations. In every case, the parts were all there; they just needed to be positioned and timed properly.
So, I can't say for certain because not all ejectors follow the same pattern, but taking the springs out will likely turn them into extractors.
