The P91DC uses a Browning-type linkless short-recoil, tilting-barrel system and a DA/SA, hammer-fired action. Its decocker-only setup is managed by ambidextrous levers mounted on the slide, paired with an exposed spur hammer and a left-side push-button magazine release.
The two-tone finish combines a stainless slide with a matte gray aluminum alloy frame, delivering a durable build with classic P-Series styling. A lanyard ring is integrated at the rear of the grip heel for retention options.
Sights are a fixed 3-dot arrangement with a white-dot front and a two-dot rear that is drift-adjustable for windage. The rear sight sits in a dovetail, and the slide shows a deep left-side "RUGER P91DC" rollmark.
Grip panels are black molded units with Ruger eagle medallions and ribbing for a secure hold. Markings include "STURM, RUGER & CO., INC. SOUTHPORT, CONN. U.S.A." on the slide and ".40 AUTO" on the chamber.
Built in the USA during the early 1990s, this P91DC reflects its period with its configuration and features, including the decocker-only system, full-size dimensions, and 10+1 capacity in .40 S&W.
