Here's a closeup of where the cock and sear meet. I don't see what I'd call a slot, it's more of a sloping ledge (I circled it in red).

Anyways, I took a binder clip and and put the "legs" between the sear so it'd act as a makeshift sear spring. I pulled the cock back and I felt the lock engage for a split second before the clip few out across the room. I have a feeling even with a proper sear spring, the surfaces of both the cock and sear are too worn down to engage.
