Notes

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.

Background

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.
