The STI Staccato C DUO is a variation of STI’s 2011 Staccato C with the addition of a Red Dot Cut in the Slide. The 2011 Series was produced by combining a modular metal frame with a polymer grip. STI has taken the technology that has won thousands of World, National, Regional and state competitions in the hands of the BEST shooters in the World and put that into a concealed carry sized platform giving you competition performance in a carry configuration. The slim profile of STI’s Staccato C incorporates FlaTec™, Their shooting technology which combines proprietary design and craftsmanship, superior materials, and our recoil absorbing grip and 2011® frame. The result is less recoil transferred to the shooter leading to faster and more accurate shooting. The DUO™ Carry (Dawson Universal Optic) system is designed to work with the Sig Romeo Zero, JP JPoint, and Shield Reflex Optics (OPTIC NOT INCLUDED).
