The Colt 1911 Competition Series pistol in .45 ACP with a stainless finish and optics-ready slide (brand part no. O1070CCSOR) pairs Colt’s classic 1911 platform with modern red dot compatibility for competitive and defensive shooters alike. Colt builds the pistol with a 5-inch barrel and serrated slide, and Novak adjustable fiber optic sights co-witness with a mounted red dot for a fast, versatile sight picture. The ambidextrous grip and thumb safety support both right- and left-handed shooters, and a single 8-round magazine ships with the pistol. Among optics-ready semi-auto handguns, this 1911 Competition Series configuration favors .45 ACP shooters who want a red-dot-compatible stainless 1911.
