That's the issue people are trying to tell you about.....Would it bend it without anything in the jaws? I haven’t had any flint or wood in the cock. It has been dry fired maybe 3-4 times (and will not again).
The fact you have nothing in the jaws is why folks are correcting you about dry fire. Dry fire, properly done is good,,,,,, dry fire without a flint or small piece of wood to simulate a flint, in the jaws to strike the frizzen, transferring the energy to the frizzen like it is supposed too, is what could be damaging the lock.
Best thing here is listen to @Comfortably_Numb and @ColonialRifleSmith and take him up on his generous offer.
