I’ve seen some posts showing some of the smaller single stacks converted to 10 mm. I don’t have any of those, but I do have a 4006. Can it be readily converted to 10mm? Obviously the chamber would need to be lengthened, but what else. What about magazines and OAL of the cartridge? Recoil spring weds changing. Extractor, ejector length? Is this something I could do myself, or does it require a real live gunsmith? What would be reall nice is to have a separate barrel for both 10mm and .40. I look forward to your knowledgeable responses.
