Lol!
I would never mess with a trigger on a carry gun. Just asking for trouble. Why do I need a 2lb trigger pull on a CCW? whats that going to say in court? Are we trying to get full auto status by lightning our trigger pulls to pop 2 rounds with 5 lbs of force vs 1 round of regular factory trigger?
Besides, if the gun messed up, it would be all factor parts, nothing added.
