The Springfield Armory 1911 Mil-Spec Semi-Auto Pistol replicates the GI issue 1911-A1, with an arched mainspring housing and a standard spur hammer and grip safety, though constructed of modern steel machined to CNC tolerances. A lowered ejection port aids in reliable function. The slide on the 1911 Mil-Spec model comes with flat surfaces, bead-blasted matte finish on the round edges, and tight serrations. Checkered grip panels have a nostalgic look and feel. True to the 1911-A1 design, the Mil-Spec semi-auto pistol comes with a standard thumb safety on the left side for a right-handed shooter and a short military combat trigger.
