Rock Island Armory continues to stretch the boundaries with the development of the XT Standard Combo. Adding to the ingenuity of the XT core design, the XT Standard Combo includes a drop-in 45 ACP barrel to make this package equipped for any shooter. Engineered with a pinned 5” barrel with blow back slide combined with our standard, crisp factory 1.36 kg - 1.81 kg trigger it offers match class accuracy and power. Includes low-profile anti-snag angle front and rear sight with skeletonized hammer and trigger with adjustable over travel stop. The XT Standard is finished with rock tough parkerized coating, fitted checkered rubber grips and comfortable extended beaver tail safety.
