The TAC Ultra Compact introduces a full tactical rail. Like all Rock Island 1911s, this series is built with 4140 Ordnance and is refined with our carefully managed hand fitting process. It's chambered in 45 ACP with a 3-1/2 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 and is fitted with skeletonized hammer and trigger with adjustable over travel stop. The TAC Ultra is finished with a tough parkerized matte coating and adds battle ready G10 tactical grips. True to all Rock Island 1911's, the TAC Ultra comes with a crisp factory 4 to 6 lb trigger to give you a great experience right out of the box.
