I'm no Ruger guru by any means, but I've done 2 or 3 tang style. IIRC, my problem was repeatability...easy without much trouble to get down around 2 pounds...but it seemed impossible to achieve consistency, varying a half pound or more on each test pull. I had to replace the existing pins with oversize stock, and drill/ream the holes to get the slop out that was causing the variations in pull weight.
