Well the Mustang is back in action.

I took the receiver off again and looked it over closely. The assembly that holds the hammer and safetymechanism dovetails into the main part of the receiver, andappeared to be slightlymisaligned with the rest of the unit. I used a smallC-clampto push things together, and the safety "almost" worked properly. Then I blew the innards out with a spray can of carburetor cleaner and oiled everything up. At this point the safety operated properly, but was very stiff. After working to the"on" and "off" positionsabout two dozen times it loosened up and operated properly. Still, thepoint where those two parts of the assembly meet did not seem to me to have as good a fit as I remembered. Then I checked the serial number on the receiver. Dang, they didn't repair mine - they sent me a different one. Now I have a barrel with one SN and a receiver with a different SN. I'm just going to live with it.

Though I'm not a real happy camper, I do have to admit that Lyman's machining on the Mustang barrel/receiver lock-upis very very precise. The originallock up was rock solid without the slightest hint of wiggle, wobble, or looseness, and has stayed that way with the 900+ shots I have through the gun. Even with the substitute receiver the lock up is the same.
