I usually will put in a 3.5 lb connector that will reduce the trigger, improve reset and LOP, and reduce overtravel. While it can also increase your accuracy and I find this mod (for me) improves my shooting speed. Good brands for this are Ghost, Scherer, and Lone Wolf trigger connectors (and others have also come and gone).
