Ruger, Security-9, 9mm Luger, 4 inch, 10 Rounds, Blued Finish, Polymer Frame

The Ruger Security-9 9mm Luger is a compact, mid-sized semi-automatic pistol built for concealed carry, range work, and duty use, offering a 4" blued alloy steel barrel, through-hardened blued steel slide with serrations, and a high-performance glass-filled nylon frame with an integrated Picatinny rail for lights or lasers; the Security-9 series uses Ruger's Secure Action—derived from the LCP and LCP II fire control systems—to deliver a smooth trigger pull with a short, crisp single-action feel and positive reset while an internal hammer provides strong ignition force and easier slide racking than many striker-fired designs. With a 10+1 capacity, 1:10" twist, 6 grooves, 7.24" overall length and a 23.7 oz carry weight, this double-action style pistol balances shootability and concealability; the checkered textured grip and drift-adjustable dovetailed 3-dot sights allow confident handling and quick target acquisition, and front cocking serrations aid manipulation. Design features like a neutrally balanced sear, bladed trigger safety, manual safety, hammer catch, and tool-free takedown address safe handling and maintenance, and buyers should note that an FFL transfer is required.
