I've owned a sauer model 90 for about 10 years now. It's a great looking and very accurate rifle. The trigger is advertised as a single set trigger but you cannot push it forward to set it. Do I have to adjust something in the trigger. I have the trigger set at about 3lbs and it is very crisp but 3oz on a set trigger would be great. Does anyone own a model 90 and have any answers for me?
