The Apex Flat Forward Set Trigger Kit for the "factory upgraded models" of the Sig Sauer P320 is a direct replacement to the factory trigger bar and curved trigger and is easily installed without the need for tools or fixtures. The patent-pending Apex Forward Set Trigger Bar reduces trigger travel and resets while the Apex Flat Advanced Trigger reduces the trigger pull weight and increases trigger reach to the natural resting position of the shooter's finger and allows the shooter to position their finger lower on the trigger face to take advantage of the increased leverage.
