About the Ruger Security-9
The Ruger Security-9 is a semi-automatic pistol chambered in 9x19mm Parabellum, produced by Sturm, Ruger & Co. since 2017. This American-manufactured firearm reflects the engineering traditions and quality standards of its country of origin, designed to meet the demands of both civilian and professional users in a competitive global marketplace. Featuring a 15-round magazine capacity, this pistol offers generous firepower for duty use and home defense. The 4.0-inch barrel provides an excellent balance between sight radius and portability, making it equally suitable for duty carry and recreational shooting. Weighing 674g (23.8 oz) empty, this firearm strikes a practical balance between manageable carry weight and sufficient mass to moderate felt recoil during shooting. The polymer frame construction reduces weight while providing a textured, ergonomic grip surface designed for secure handling in all conditions. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform.
The Security-9 revived Ruger's iconic 'Security' brand name, originally used on their classic Security-Six revolver from the 1970s. Its internal aluminum chassis within a polymer frame was an innovative approach to providing structural rigidity at a budget price point, making it one of the most affordable name-brand 9mm pistols available.
