Judging weight of trigger pull is pretty difficult by feel. We all know when a trigger is light, or heavy, or crisp, of dragging, but it's just a guess when it comes to pounds of pull. If you don't have a trigger pull scale there's an easy way to get an approximate weight. It's a two person job. Connect a gallon jug to your trigger with a loop of string and have someone slowly fill the jug with water until the trigger breaks - then weigh the jug.
My FIL took it a step further... he has a jug that is mark by the pound... with a special one for 2.5, that is where all of his guns are adjusted to.
