Ruger Security-9 Full-Size 9mm Luger, 4 in Barrel, Black Oxide, 17+1 Capacity (2024)
This full-size 2024 Ruger Security-9 pairs a 4 in alloy-steel barrel and black-oxide slide with Ruger’s Secure Action internal-hammer system. It offers a 17+1 capacity, a rigid one-piece aluminum chassis with full-length guide rails, and an integral accessory rail. It ships with three steel magazines and features practical fixed-front/drift-adjustable rear sights.
Operational details include a recoil-operated, locked-breech action, manual thumb and trigger safeties, a neutrally balanced sear, a hammer catch, and a loaded-chamber view port. Takedown is tool-assisted via a pin and does not require a trigger press. The slide is marked "SECURITY-9," the barrel hood is marked "9MM LUGER," and the frame reads "RUGER • PRESCOTT, AZ • USA."
The glass-filled nylon frame keeps weight down while the internal aluminum chassis adds rigidity. Front and rear slide serrations aid manipulation. The front sight is a fixed blade with a white dot; the rear sight is dovetailed and drift-adjustable for windage. The slide has no optics cut.
The 1:10-twist barrel supports common 9mm loads, and the Secure Action fire-control provides a positive reset. A frame-mounted integral accessory rail with multiple cross-slots accommodates lights or lasers. The pistol is made in the USA and includes one 17-round and two 15-round steel magazines, one of which has an extended baseplate/grip sleeve.

The dovetailed rear sight is drift-adjustable, and the front sight is a fixed blade with a white dot for a clear sight picture.
