Extractor probs

Fabian,

I'd like to add a caution to my friend John Sabato's chamber-polishing suggestion. An original 9mm chamber is not a simple boring, but a complex machining of a cylindrical part and a minutely smaller conical part, including a slight, but visible, step between the two. Simply polishing the chamber as he suggests may not reach the entire surface, and may alter these relationships. Care must be taken also in the area of the chamber mouth, as this is where the cartridge head-spaces.
