The Ruger SR40 is a semi-automatic medium-frame pistol chambered in .40 S&W. The SR40 has identical features to the Ruger SR9, the company’s first large caliber striker fired pistol.
When a pistol is striker fired it means the trigger controls an internal
arm that hooks the firing pin. Once the trigger is depressed the firing
pin is pulled back and then sprung forward to strike the cartridge’s
The SR40 features an alloy steel slide with either a Nitridox protective black finish or brushed stainless steel finish, and a glass-filled nylon grip for increased durability. The SR40 is equipped with a 3-dot sights, which are adjustable for windage and elevation. The SR40’s grip has a reversible backstrap that offers a flat or arched grip fit.
Additional features include ambidextrous manual safety and a trigger safety. With the trigger safety, the only way the gun can fire is if the trigger is actually pulled. This prevents accidental discharge if dropped. The SR40 also has a ambidextrous magazine release, an under-barrel Picatinny rail for easy mounting of accessories, and a magazine finger grip extension that can be added for increased ergonomics. The SR40 is available in both 10 and 15-round magazines.
Ruger recommends the SR40 for open or concealed carry.
