I had the same problem on my 1982 Challenger II. Miss fires with a decent indent. I ordered a new inner and out hammer spring and have not had one miss fire since. They are $6 a piece plus shipping. Puts both springs around $20.

Only way to go I would imagine. A new firing pin spring would not help at all for your problem unless it was binding and I doubt that it is.

Two springs on bottom right of this page.


They will be very tight going in.

The only other thing that I could think of is a pinged chamber from the firing pin. (dry firing cause) but probably not.
