Ruger Security-9 9mm Luger 4 inch 15+1 Polymer Frame Adjustable Sights

The Ruger 3816 Security-9 is a mid-size 9mm Luger handgun in the Security-9 series that blends Secure Action hammer-fired operation with a 4" blued alloy steel barrel, 15+1 capacity and a black glass-filled nylon frame with an integrated Picatinny accessory rail, making it a reliable choice for concealed carry, everyday carry and home defense. The factory-installed Viridian E-Series red laser mounts low on the rail and trigger guard with ambidextrous push-button activation to aid quick target acquisition in low light, while dovetailed drift-adjustable rear sight and fixed front sight allow easy sight changes to suit personal preference. Built with a through-hardened alloy steel slide featuring front serrations and a precision-machined hard-coated aluminum chassis with full-length guide rails, the pistol delivers durable, consistent function and a smooth, single-action-like trigger pull with positive reset courtesy of Ruger's Secure Action derived from the LCP II. Controls include a manual safety, bladed trigger safety and internal hammer catch for added security, and the design allows takedown without special tools or trigger pull; FFL transfer required. This Ruger Security-9 balances duty-grade construction, practical ergonomics and integrated laser capability for defensive and carry applications.
