The Ruger Security-9 is a compact pistol designed for easy concealment and compatibility with a range of holsters. Its construction features a black oxide-coated, through-hardened alloy steel slide and barrel, paired with a high-performance, glass-filled nylon grip frame. The pistol's precision-machined, hard-coat anodized aluminum chassis includes full-length guide rails, enhancing durability and stability. It operates with Ruger's Secure Action fire-control system, which integrates a protected internal hammer and a bladed-safety trigger, providing a short, smooth pull, clean break, and positive reset. The textured grip frame ensures a secure hold, while the dovetailed sight system, with a drift-adjustable rear sight and fixed front sight, offers high visibility and the option to swap sights for different colors. The internal hammer of the Secure Action system allows for easier slide manipulation compared to many striker-fired models. Safety features include an integrated trigger safety, a neutrally balanced sear with strong spring tension, and a hammer catch to prevent unintentional firing. The Security-9 is designed for safe and straightforward disassembly without special tools or a trigger pull, and it comes with two alloy steel magazines.
