I adjusted mine down to 1.5lbs. It's not hard to do yourself but if you don't feel like you can handle it with confidence, don't mess with it.
Is it a Steyr you are adjusting? Asking because I had a slam fire on one of my Steyrs that was set at 2 lbs and it forced me to get educated.
There is a very detailed trigger adjusting instruction manual put out by Steyr that qualified Steyr gunsmiths have access to. I have a copy but swore on my right nut that it would never be shared.
