You could try some of the yellow jp springs. They lighten the trigger pull quite a lot.
Some people have smoothed the stock trigger out by judicious application of lube and dry-firing. Might be cheaper than a $400 trigger.... If you do go the new trigger route, the RRA match triggers are only about $120US and might be an option. I really like the one I have.
One other option if you are a real cheap bastard like me, is to order a single stage dpms fcg kit. I have one in my cheapie ar. Only cost me about $50 plus shipping from brownells.
