Ruger Security-380 3855 | .380 ACP | 3.42″ Barrel

The Ruger Security-380 (Model 3855) is a compact, semi-automatic pistol chambered in .380 Auto with a 3.42″ barrel and a lightweight, textured glass-filled nylon frame. It features Ruger’s Lite Rack system for reduced slide effort, a bright fiber-optic front sight with a drift-adjustable steel rear sight, and Ruger’s Secure Action fire-control system. A compact pistol red dot such as the Holosun 507K would pair well for faster sight acquisition while staying well under $1,000.

Common applications for this pistol include range training and everyday concealed carry due to its compact size and reduced felt recoil.
