What is happening to the sear?

[Crane Senior]

I was cleaning my rifle today and when I pulled the lock I ran into this (it’s been a while since I cleaned the lock). First I have no clue why this happened, the trigger pull is fine. Secondly, should I stone or file it down? An inquiring mind wants to know. Thank you in advance.

Smooth it and the trigger and keep lube on it.

If you dry-fire a set trigger a lot, do so with the hammer down, not at half-cock, That will allow the sear to move when hit with the second (rear/set) trigger bar, rather than locked in place with the half-cock notch

I do not dry fire with the hammer at half cock that's why I'm a little confused. I'm now guessing there is a burr on the trigger, I'll have to look at that.

If the sear and trigger pivots are not exactly inline (as if drilled at the same time) the trigger bar will "saw" on the sear tail. Polish and grease.

OK, I can polish and grease, I'm guessing this will continue however?

I'd be polishing the tops of the trigger bars too,,
