Colt custom combat commander 45 acp Factory parts steel non adjustable trigger. I set hammer hooks 18 tho in height I stoned dear in ed brown fixture I polished trigger bow and all parts and was able to get around 3.5 pound pull according to scale. Thanks Around 15 slide drops hammer began to follow. I bent dear leg of 3 leaf in and I have racked slide hard until hands raw with no hammer follow. Trigger is now around 4.5ish pounds. Why and what am I doing wrong? Do I need new parts to be able to achieve 3.5 Is the steel trigger messing it up, everything on web says light weight aluminium or plastic triggers needed to stop bounce. How can I adjust the 3 leaf spring under control and precision?
