When setting sear spring tension, your pre travel tension should be about 1/3 of the total trigger weight. This can be measured by using your trigger spring scale and pulling on trigger and stopping just before the trigger/disconnector contact the sear, it is a little tricky but if you try it a couple of times you can figure it out.
2 3/4 = 44 oz...... so pre travel should be 14-15 oz., anywhere between 12 and 16 oz. will work, the lower the total trigger weight the more exact this needs to be, when get to 2 lb or below it needs to be exactly 1/3. Oh, and you adjust this tension with the center leaf.
What kind of gun/trigger are we talking about, some triggers have a tab on the front left area of the bow that can be bent forward to reduce the pre travel, if yours doesn't have this you can (very carefully) make 2 vertical slits on the bow so that you now have a tab to bend, I've seen one done that worked just fine but didn't have alot of meat left on the bow.
Another option is to drill a hole through the frame (or grip) and install a set screw that will contact the trigger bow in the left front area, very precise and easy adjustment compared to R&R trigger to bend tab. I wouldn't have a problem doing this to a plastic grip but I don't think I could do it to a metal frame.
