IF, and that is a great big if, it was produced out of some kind of decent tool steel, say, O1, since it's everywhere, you might get away with just letting it be, and not shooting it every day for the next thirty years.
How Parker's ever got the nickname of "Old Reliable", with all that stuff inside is beyond me. Plus, so very many of them are seen wearing the fashionable bolt 'twixt the split in the head of the stock that we are left to wonder who's gun was the "old unreliable"?
Anyway, good luck. You paid a small enough price that some sear train hardware and a fitting of same by someone in the know shouldn't be that painful. Maybe.
Best,
Ted
