The Tisas 1911DS FF 9mm pistol (brand part no. 12500032) is a double-stack 1911 with a 4.25-inch Commander-length bull barrel on a full-length steel frame, finished with an AOS optic cut. Tisas partnered with Agency Arms on the Agency Optic System, a modular plate system that lets one factory cut run many red dot footprints, and every AOS-cut pistol ships with an AOS-to-RMR plate with a built-in backup iron sight. The Carry 9 DS FF line this pistol belongs to pairs a steel frame with an accessory rail, a titanium firing pin and a manual thumb safety. The double-stack magazine gives far more capacity than a traditional single-stack 1911. For a shooter who wants a modern carry or duty 1911 already cut for an optic, this is the 4.25-inch AOS configuration.
