The Tisas 1911 Duty Double Stack combines traditional 1911 handling and a crisp single-action trigger with a modern 18+1 capacity. Its full-size steel construction, 5" barrel, and polymer double-stack grip module provide a solid, controllable platform for range, defensive, and duty use.
The slide features a direct-mount RMSc optic cut, allowing compatible red-dot sights to sit low enough for lower 1/3 co-witnessing with the factory sights. A 1913 accessory rail, ambidextrous thumb safety, removable aluminum magwell, and Flat Dark Earth finish complete the package.
