Ruger SR Series - Variants

Variants

• The Ruger SR9 started to ship in October 2007. It is the first model of the Ruger SR series. Its a 9mm model, and it is shipped with two 17-round, flush-fit magazines and a loading tool.

• The Ruger SR9c started to ship in January 2010, according to Ruger. The SR9c is lighter and dimensionally smaller compared to the SR9, but it has the same grip width (measured across safety levers) as the full-sized SR9. The manual safety, adjustable rear sights, and updated version of the trigger are all present in the compact version also. In contrast to the SR9 recoil spring assembly the SR9c pistols are fitted with a dual recoil spring assembly. The SR9c is normally supplied with two magazines. The standard 10 round compact magazine features a flat bottom floor plate, with an extended floor plate also included. The second magazine is a full-size 17 round unit featuring a grip adapter that transforms the short compact SR9c grip into a full-sized grip. However, in jurisdictions where the number of rounds in a firearm are limited by law the SR9c is shipped from Ruger with two 10-round magazines and two extended floor plates. Additional retraction grooves (serrations) are located on the front sides of the SR9c slide, making it easier to operate and press-check the slide. The Ruger SR9c was chosen as the Shooting Industry Academy of Excellence's Handgun of the Year in 2010.

• The Ruger SR40 started to ship in October 2010 to dealers. This is a full-size variant chambered in .40 S&W. The full-size .40 S&W magazines hold 15 rounds. The SR40 ships with two 15-round, flush-fit magazines and a loading tool. The basic overall dimensions and barrel length of the SR40 are the same as for the SR9, though the through-hardened stainless steel slide was modified and is 0.060 in (1.5 mm) wider than the slide of the SR9. The added mass of the SR40 slide reduces slide velocity during cycling to help reduce felt recoil and increase service life expectancy.

• The Ruger SR40c started to ship in June 2011. Like the SR9c is to the SR9, the SR40c is a compact version of the SR40. It is dimensionally equal to the SR9c; and unlike the SR40 is to the SR9, it also weighs the same. The SR40c ships standard with a 9 round magazine with an optional extended baseplate, as well as a full-size 15 round SR40 magazine with a removable sleeve. In jurisdictions that prohibit large-capacity magazines, it ships with two 9 round magazines and two extended baseplates instead.

• The Ruger SR45 chambered in .45 ACP was announced in January 2013 and is slated to appear at the 2013 SHOT Show annual tradeshow for the shooting, hunting, and firearms industry.

• The Ruger SR22 is a pistol chambered for the rimfire .22 Long Rifle cartridge it does not share design and ergonomic commonalities with the centerfire SR9(c), SR40(c) and SR45 pistols, instead it mimics the ergonomic features of the Walther P22. Mechanically the SR22 significantly deviates from the other Ruger SR series pistols. The action of the SR22 is of the straight blowback type that utilizes a fixed barrel design in which the slide during firing is kept in its forward position by a combination of the force exerted by the recoil spring and the inertial weight of the slide assembly at the moment of firing. After firing, due to the generated bolt thrust during firing, the slide recoils to the rear permitting the extraction and ejection of the spent cartridge case. Upon return of the slide to its forward position by the recoil spring, a fresh cartridge is picked up from the magazine and loaded into the barrel chamber. Due to the low bolt thrust generated by the .22 Long Rifle chambering the SR22 features an aluminum slide to keep the (inertial) weight of the slide assembly down. Further the SR22 features a double-action/single-action trigger system with a rounded spur external hammer and has a visual inspection port in the form of a hole in the top of the slide and the back of the barrel that functions as a loaded chamber indicator. The SR22 started to ship in January 2012 and is shipped with two 10 round magazines and replaceable grips for small or large hands.
