The Girsan Witness 2311 CMXX 45 ACP 4.25" Ported With Integral Compensator Bull Barrel delivers double-stack 1911 performance in a compact, carry-ready package. Built around a polymer frame with beavertail and accessory rail, it pairs a tuned single-action trigger with a lightening-cut, optic-ready slide using the RMSc footprint for modern red dot options. The factory ported bull barrel and integral compensator help tame recoil and keep the pistol flat for faster follow-up shots.

This Witness 2311 CMXX is well suited for range use, defensive carry, and training where a controllable .45 ACP platform is desired. Ambidextrous thumb safeties, improved grip texture, and a flared magazine well support confident handling for a wide range of shooters. With its 11+1 capacity, fiber optic front sight, and thoughtful ergonomics, this pistol reflects Girsan’s focus on practical innovation and solid craftsmanship in the 1911-style handgun market.
