Iver Johnson Arms 1911 is a Series 70 pistol which means there is no firing pin block and comes with a flat serrated steel mainspring housing to hold up to the rigors of an everyday shooter. It features a finger relief cut near the trigger guard for a more comfortable shooting experience. It utilizes a forged slide and cast frame which are CNC machined and then hand fitted to exceptional tolerances. Each slide is fit to an individual frame to give it a tight out of the box fit. Includes one magazine gun lock manual and a hard black plastic lockable gun case.
