Re: Rem 870 ejector spring question
The Model 870 is notorious for dumping its extractors. The shops where I worked kept a handful of them as well as plungers and springs as replacements since often, the spring and plunger went into the tall grass along with the extractor.
It was pretty common in working on those guns to find that the owner had replaced the extractor, but cheaped out on the spring and plunger, using a hardware store spring and a piece of nail instead. The extractor didn't hold the shell tightly enough, with the results described above.
