Armscor/Rock Island Armory sizes the primary barrel at 5 inches and finishes both the frame and slide in black Parkerize, and an MPS1 adjustable rear sight pairs with a fiber optic front sight for precise aim. G10 grips give a secure hold, and an ambidextrous manual thumb and grip safety supports both right- and left-handed shooters. The trigger breaks at 4 to 6 pounds.
