You all might want to check me on this, but with back of the napkin calc's for the tune of the lower link, moving the contact bar out just lengthens the fulcrum distance on the lower link to the SEAR thus increasing the force needed to be applied by the trigger. I looked at this by moving the new lower link fulcrum point from Chris's tuned location of 1/4 inch to the right only out to 3/16 inches forcing the whole lower link to be moved to the right by 1/16 inch. The input fulcrum distance from the trigger remains the same and the output fulcrum length on the lower link gets longer. The distance from the SEAR fulcrum point to the contact point gets longer also by the same 1/16 inch. Ultimately, it looks as though the force required in this will actually go up. From the back of the envelop calculations, if you assume the original force required to be applied to the sear by the contact bar is 1.0, then the 1/4 inch tune by Chris drops the force input required at the trigger from a relative value of 1.38 to about 0.54. With drilling the new hole in thelower link at 3/16 inches rather than the 1/4" of Chris's mod, you move the whole lower link and subsequently the contact point on the SEAR to the right by 1/16 of an inch; a force advantage. Hower, the force reduction on the SEAR does not make up for the loss of advantage by moving the fulcrum point and the napkin calcs say that the new resultant force required would be a relative 0.762. Worst case, there will be no change what-so-ever. So to really see an advantage, I think you would have to have a different Lower Link, SEAR and SEAR fulcrum point - essentially a whole new trigger assembly. I think Chris's change is the best you can do for the existing trigger components and trigger fulcrum points. By the way, I used measurements off Chris's photos so there is some error involved.
