Two broken extractors, two limp extractors (50+ years old) in autos.
"Inoperable" for how long? That is, a malfunction that requires fifteen seconds to clear is inoperable? Or, only a gun that needs repair to put it back in action is considered inoperable?
I've had revolvers tied-up by a grain of unburned powder under the extractor star, or a case rim under the extractor star; there's nothing wrong with the gun, but they sure were inoperable.
