The new triggers are better.
If you want an easy fix get the Apex DCAEK.
An easier fix would be to polish the trigger bar loop, sear (where it contacts the trigger bar loop and the striker), the striker face, the striker block and where the trigger bar contacts the striker block. In about an hour and a half you can really improve the trigger.
I just did a striker block two weeks ago, you can see the before and after in this pic.
