Jack Weigand describes the proper way to set the tension on a sear spring in his article on trigger jobs:

http://www.brownells.com/aspx/NS/General/D...?f=bt002005.pdf

Basically, he recommends setting the left leaf (that presses on the sear) to the same net tension as the center leaf (which presses on the trigger/disconnector). If you have a good trigger pull gauge, you can meausure the forces at the trigger from each leaf.

If this is a stock 1911, a target of about 5# would be sensible for trigger pull. That means about two pounds pressure EACH on the two sear spring leafs mentioned above.
