Tisas 1911 Double Stack FF Carry 9mm Pistol, 4.25-inch Barrel, 18+1, AOS, Black The black Tisas 1911 Double Stack FF Carry is a 9mm pistol with a 4.25-inch barrel, an 18+1 capacity and the AOS optics-ready configuration. Its double-stack magazine layout accommodates the listed 18-round magazine capacity, with the additional round represented separately by the chamber in the 18+1 designation. This package includes two 18-round magazines. The 4.25-inch measurement identifies barrel length, not the pistol's overall length. AOS identifies the optics-ready version; an optic itself is not listed as part of this package. These details distinguish the exact Carry configuration without assuming that every 1911 accessory or optics mount shares the same fit.
