The Ruger Security-9 Model 3851 blends Ruger’s renowned performance and reliability with a vibrant Cobalt Kinetic Blue Cerakote slide, creating a bold yet practical sidearm. Built around a 4-inch barrel and chambered in 9mm, this pistol is ideal for home defense, range time, or everyday carry in a larger format.
The lightweight glass-filled nylon frame and Secure Action™ fire control system offer a consistent trigger pull with a short, crisp reset, similar to a striker-fired design while utilizing a reliable, internal hammer-fired system. The drift-adjustable rear sight and front white dot sight provide quick target acquisition in varied lighting.
This model includes two 15-round steel magazines, an integrated accessory rail, textured grip frame, and manual thumb safety, all contributing to its functionality and shooter-friendly ergonomics.
