I think you may be right, once I think about it. I haven't looked at my 1873's in a while. It may just be one piece, the spring in the part itself. You may need a replacement extractor.
If the ctg. is held tightly by the extractor, it should break out with some gusto once it hits the ejector.
A phone call to Cody Conagher, Jimmy Spurs, or Pioneer may be worth the effort. Those guys are very knowlegable and will usually take the time to help out.
Let us know how it works out.
