Sturm, Ruger & Company, Inc.'s SR40 pistol, the latest extension of the SR9Series, striker fired line of pistols provides a large caliber option in one of the slimmest and most ergonomic full sized pistols.

The SR40 is built on the same high-performance glass-filled nylon frame as the SR9, offering all the great ergonomic features that made the SR9 a success: a slim, narrow frame with a short trigger reach, reversible backstrap for an arched or flat configuration, and fully ambidextrous controls. The through-hardened, stainless steel slide on the SR40 is 0.060-inches wider than that of the SR9; the added mass of the slide reduces slide velocity during cycling, reducing recoil and improving service life.

The SR40 weighs 27.25 ounces (with an empty magazine) and ships with two fifteenround, flush-fit magazines. A loading tool is also provided, although an anti-friction coating applied to the magazine body greatly reduces the force required to load the magazines to full capacity. The SR40 features a 4.1-inch barrel length, fully adjustable three-dot sights, and an integral accessory rail.

The SR40 offers modern safety features such as a visual and tactile loaded chamber indicator, striker blocker, trigger safety, magazine disconnect, and a framemounted ambidextrous manual safety.
