This compact C3.6 HD pairs a 3.6 in bull barrel with a lightweight aluminum-alloy frame and a polymer 2011-style grip module featuring aggressive texture. The 2011 platform delivers a single-action, semi-automatic setup with a 15+1 capacity in 9mm Luger.
The slide is cut with front and rear serrations and includes an optic cut with cover plate. Staccato’s HD HOST direct-to-slide optic interface is built in, and the pistol uses an improved recoil system aimed at maintaining control and consistency. Iron sights include a high-visibility green-dot front and a plain black rear.
Controls and protection features include an ambidextrous manual thumb safety; the pistol is Series 70 style with no mechanical firing pin block and relies on an inertial/titanium firing pin and heavier firing pin spring for drop safety. A skeletonized trigger with lightening windows and a skeletonized commander-style hammer support a crisp, responsive feel. An accessory rail adds mounting flexibility, and the external flared/carry magwell speeds reloads.
The C3.6 HD uses Staccato 2011 double-stack steel magazines; three 15-round Staccato mags are included. Manufactured in the United States in Florence, Texas.
