Worked on the trigger/sear

Quote:
It could be the angle in which the tip of the trigger & the sear of the hammer have in relation to each other too.
I shot the Uberti '58 again today just to confirm the trigger is that light. It was and after two cylinders, I gave up. I had two shots go off when I was positioning my finger on the trigger!

I tore it apart this evening and examined it through a loupe magnifier. Sloppy machining was abundant. First, the angle was barely 90 degrees to the hammer pivot point. But a burr on one end of the sear surface was all that was keeping the hammer from slipping. That explains why the pull changed so quickly over about 100 rounds.

With a lot of reassembling and checking, I filed/polished an angle into the sear surface.

Now, I've got a 2 pound trigger. BUT I ALSO HAVE A LITTLE CREEP. But I think it will be unnoticable when firing freehand.

I also may have removed the hardening, I'll just have to see how it wears.
