model 60 still locking trigger pull at 80% pull

Certainly could cause the stoppage you describe. Definately some abnormal peening at the top of the firing pin bushing.

I wonder if the peening is from dry firing, and causing the shoulder of the pin to contact the hole?

Can the bushing be replaced? Or should I file it flat and see if problem goes away?

Possibly from a damaged, bent, or imroperly installed hammer nose? A properly fit hammer nose should not create that damage.
The "shoulder of the pin" does not reach the hole in the bushing.....looks like the end of the nose is striking the top of the hole.

OK My job is done here. I filed-off the raised area with a very fine file, and returned to original hammer, See pic. Thanks for everyones help. and scooter didn't get a book commission if book was bought. I'm only missing a couple parts, not too bad. I'm just kidding.

Oh ya, I put in some empty casings and cycled at least 200 strikes, the strike is now centered and no scratches. Like Armorer said, the ebay hammer must have a misaligned firing pin.

PS, the back of the barrel was rubbed "shiny", possibly from the cylinder being pushed forward by the raised part that I've since filed away.
