The Tisas 1911 Duty DS B9R is a full-size, all-steel 9mm double-stack pistol built around the familiar 1911 operating system. Its 5-inch bushing-less bull barrel uses a precision-machined target crown and a full-length guide rod to support consistent accuracy and controlled recoil. The slide is cut for direct mounting of compatible RMSc and 507K footprint red-dot optics, while the included fiber optic sights provide a lower 1/3 co-witness. Textured synthetic grips, 25 LPI checkering, an ambidextrous thumb safety, grip safety, and a universal 1913 accessory rail provide practical control and customization for duty, training, and defensive use.
