The TAC Ultra FS introduces a full tactical rail. Like all Rock Island 1911s, this series is built with 4140 Ordnance steel and refined by our carefully managed hand fitting process. This pistol is chambered in 45 ACP with a 5 inches button rifled barrel supported by a full length guide rod and full dust cover. Includes a low-profile adjustable rear sight and high-visibility fiber optic front sight. Also fitted with a skeletonized hammer and trigger with adjustable over travel stop. The TAC Ultra is finished with a tough parkerized matte coating and has battle ready G10 tactical grips. True to all Rock Island 1911s, the TAC Standard comes with a crisp, factory 4 to 6 lb trigger to give you a great experience right out of the box.
