Design and response.
Introduced in late 2017 as an improved, full-sized version of the Ruger LCP II, the Security-9 features a light trigger pull, trigger safety, "Secure Action" hammer-fired single action fire control system. The Secure Action combines the smooth trigger pull of the LCP with the short, crisp feel and positive reset of a single action. The Secure Action hammer provides strong ignition force yet allows for easier slide racking when compared with many striker-fired pistols. The Security-9 also features a dovetailed, high-visibility sight system with drift adjustable rear sight and fixed front sight, manual safety, a neutrally balanced sear with significant engagement and strong spring tension; and hammer catch to help prevent the hammer from contacting the firing pin unless the trigger is pulled, a safe, easy takedown with no special tools or trigger pull and a rugged construction with blued, through-hardened alloy steel slide and barrel, precision machined, hard coated aluminum chassis with full-length guide rails and high-performance, glass-filled nylon grip frame. The Security-9 has been praised for its reliability and low price.
