The Howa trigger is a bear to adjust. Basically if you try to remove creep by turning the sear engagement screw(rear of the trigger housing) in the safety may stop working. The screw in the front of the trigger housing by turning the screw out will reduce trigger pull . I would take it to a Gunsmith that has worked on them before and Cheaper yet is to buy a Timney trigger. The factory trigger is removed with one phillip head screw. Replace it with the Timney and your almost set. The safety bar on the timney trigger protrudes a little more forward then the factory safety bar and will hit the inside of the trigger cut out in the stock. You can see it hittingby installing The Timney putting the barrelled action back in the stock..removing the bottom floorplate assembly and working the safety back and forth. WIth a dremel tool or file remove stock material until it no longer hits(there will be very little stock material removed fwiw).
