The Rock Island Armory M1911A1 Tact II pistol in .45 ACP with a black finish and 4.25-inch barrel (brand part no. 51487) is a Commander-length 1911 built with the tactical features Armscor’s Rock Series is known for. Rock Island Armory equips the pistol with adjustable sights for precise zeroing and an ambidextrous safety for right- or left-handed shooters, and the serrated slide supports confident manipulation. The 4.25-inch barrel offers a more concealable footprint than a full-size Government model while retaining full .45 ACP power. Among Commander-length semi-auto handguns, this M1911A1 Tact II configuration favors shooters who want a more concealable 1911 without giving up caliber.
