The Springfield Armory® Operator pistol was the first pistol offered by a major 1911 manufacturer having a light-mounting rail forged directly into the frame. While others have followed their lead, Springfield still offers the most comprehensive line of 1911 light-rail guns available. The Standard Picatinny mounting platform on this Loaded MC OD Green Operator readily accepts the most popular whitelight and laser illumination devices used by military spec-ops and law enforcement tactical teams. These fully-capable extreme-duty firearms are truly the best of the best.
