Ruger SR40

About the Ruger SR40

The Ruger SR40 is a semi-automatic pistol chambered in .40 S&W, produced by Sturm, Ruger & Co. since 2010. 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 striker-fired action provides a consistent trigger pull for every shot, simplifying training and reducing the manual of arms - a design philosophy that has become the dominant paradigm in modern defensive handguns. The 4.1-inch barrel provides an excellent balance between sight radius and portability, making it equally suitable for duty carry and recreational shooting. Weighing 772g (27.2 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 SR40 represented Ruger's entry into the full-size .40 S&W striker-fired market, building on the success of the SR9. While the .40 S&W cartridge has seen declining popularity in favor of modern 9mm defensive loads, the SR40 earned a loyal following for its combination of power, accuracy, and Ruger's trademark durability. The pistol's multi-layered safety system made it particularly appealing to new shooters and agencies requiring manual safety-equipped duty weapons.

Ruger SR40 specifications

The SR40 was built on the same proven platform as the SR9, adapted for the higher pressures and greater recoil impulse of the .40 S&W cartridge. The trigger pull averages around 6.5-7 pounds with a short, tactile reset that improves significantly after break-in. A compact variant, the SR40c, was introduced in June 2011 with a shorter grip and barrel for concealed carry. The SR40's loaded chamber indicator on top of the slide provides both visual and tactile confirmation of a loaded chamber. The pistol was popular with law enforcement agencies as a duty sidearm.
