Sturm, Ruger & Company, Inc. has introduced the Ruger SR40 pistol to provide a higher-caliber option in the full-sized SR Series striker-fired pistol line that includes the SR9 and SR9c.
Built on the same glass-filled nylon frame as its predecessors, the SR40 offers similar ergonomic features of the SR9 and SR9c — a slim, narrow frame with a short trigger reach, reversible backstrap for an arched or flat configuration, and ambidextrous controls. The stainless-steel slide on the SR40 is .06 inches wider than the SR9. The added mass of the slide reduces slide velocity during cycling, reducing recoil and improving service life, according to Ruger.
The SR40 weighs 27.25 ounces (when empty) and ships with two 15-round magazines. A loading tool is also provided, although an anti-friction coating applied to the magazine's body reduces the force required to load the magazines to full capacity.
The pistol also features a 4.1-inch barrel, adjustable three-dot sights, and an integral accessory rail. It offers safety features such as a visual and tactile loaded chamber indicator, striker blocker, trigger safety, magazine disconnect, and a frame-mounted ambidextrous manual safety.
