I have adjusted trigger pulls to extremely low weights but only under specific circemstances. Some benchrest rifles are adjust to very low pulls as are some silhouet rifles. In many instances special triggers are used, built with very tight tolerances and light weight trigger blade components they allow extremely light pulls, safely. Even then I get the willies... There really doesn't have to be any reasonable cause for an attorney to file a suit, just a connection.. If someone gets hurt with the rifle there will likely be a suit, even if it was not the triggers fault... Justice has little to do with it, just money... I've found that 3 pounds perhaps a bit less, is about the least most can handle safely in the field and that is a very useable weight. Learning to shoot is still more important than the equipment.
