I have been looking for a band type extractor for my 187. I have 2 bolts. One has the extractor arms and plungers and springs. The other uses a band type extractor. Numrich is sold out of the band extractors - has been for quite a while. Does anyone know or use another parts place that might have one of these? Any help will be appreciated! Of perhaps you have an old 187 you would part out?
