Wow! Whatinheck were you doing taking that trigger apart in the first place? Just for fun, I guess, as there is no other reason I can think of.

First, the loop goes up. Second, the long end of the spring goes to the rear and bears on the short pin in the hand.

I recommend using a drift punch as a slave pin to install the spring and insert the pin that holds it into the trigger. Then insert the long pin of the hand partway into the trigger, while using a small screwdriver to push up on the tail of the spring and slip the short pin of the hand under it.

If you did it right, you now have tension on the hand to move it forward. The hand is not meant to move from side to side, only in a short arc back and forth.
