I've just resurrected a 99C Series A receiver from a box of parts, and the bolt is low. So low that the hammer indicator is not indicating. I can pull the bolt up with my finger to raise the hammer indicator, and get the bolt up to where it should be, almost flush with the top of the receiver.

Should I put the lever in a vise and beat on the nose, to tighten the arc? Weld and grind on the landing pad in the receiver? Do nothing, and live happily ever after? Toss the whole project in the trash, and pretend like it never happened?

Thanks!
