Built on a forged frame and slide, the Mil-Spec carries on Springfield Armory's long legacy of quality 1911s. Traditionally styled and built on a full-size frame, the Mil-Spec features a 5, match grade barrel and rear slant serrations on the slide. The mainspring housing is the original arched style found on G.I.-issue 1911-A1s, giving you a classic look with modern upgrades for improved performance and reliability.
