If someone could make a buck, reproducing these parts. They are the only parts on my Combat Master that show any wear, and I'm not aware of any other parts that fit. The compact Olympic/Safari Arms pistol - don't remember the nickname - has a similar recoil spring guide (it seats against the slide stop pin, a la Combat Master), and the whole recoil assembly is available for about $50. In the absence of the proper Detonics parts, the Oly/Safari parts could probably be modified to work.
