1970's Taurus Model 80 Trigger Pull Weight

[MarkSteinCA]

I have a mid 1970s Taurus Mod 80 which has the mainspring adjustment. What is the recommended double action weight for this gun? I'd like to adjust it to close to what it came from the factory like, not interested in lowering weight to make it easier.

12-15 lbs? Whatever a S&W is.
