The '''Ruger SR-Series''' is a line of [[semi-automatic pistol]]s manufactured by [[Sturm, Ruger & Company]]. At {{convert|1.18|in|abbr=on|1}} thick through the [[pistol grip|grip]], it is touted by Ruger as one of the thinnest [[Magazine (firearms)#Box|double-stack]] pistols available. The SR-series has been marketed as a backup/concealment weapon for [[Police|law enforcement]] as well as for [[civilian]] [[Concealed carry in the United States|concealed carry]]. The Ruger SR9 chambered for the [[9×19mm Parabellum]] cartridge was introduced in October 2007, and the slightly smaller SR9c came out in January 2010.<ref name="wg">[http://world.guns.ru/handguns/hg207-e.htm “Ruger SR 9 pistol (USA)”] {{webarchive|url=https://web.archive.org/web/20071028004216/http://world.guns.ru/handguns/hg207-e.htm |date=2007-10-28 }} World Guns Web site.

==History== ===Development=== Starting in the early 2000s, the rapid growth of [[legislation]] and [[regulations]] allowing concealed carry by law-abiding citizens in various [[jurisdiction]]s created a large market for handguns manufactured specifically for such use.<ref name="gb"/> Desirable characteristics for firearms of this type include: small size, thinness, [[Magazine (firearms)#High-capacity magazines|high magazine capacity]], lightweight construction (often achieved through the use of [[polymer]] [[Receiver (firearms)|frames]]), stealthy darkened [[stainless steel]] [[Pistol slide|slides]], [[Iron sight#Contrast enhancements|high visibility and/or night sights]], and large [[Ergonomics|ergonomic]] [[Ambidexterity|ambidextrous]] [[Safety (firearms)#Manual safety|manual thumb safeties]] and [[magazine release]]s.<ref name="gb"/> Ruger specifically designed the SR9 pistol to address the very active and profitable concealed-carry handgun market segment and it possesses the majority of the aforementioned attributes.<ref name="gb"/>

===Recall=== On April 9, 2008, Ruger [[Product recall|recalled]] the SR9 model because, under certain conditions, it can fire if dropped with the manual safety off and a round in the chamber.<ref name="srr">[http://www.ruger.com/SR9Recall/ ”Ruger SR9 Product Safety Warning And Recall Notice”] Sturm Ruger Web site. Accessed December 9, 2008.</ref> This condition can occur in pistols manufactured from October 2007 to April 2008. Ruger designed a new trigger group which corrects this issue.<ref name="srr" /> It includes, among other things, adding a pivoting inner blade to the trigger itself, similar to that on the [[Glock pistol]]. This blade must be depressed to allow the trigger to be pulled. It also serves as an overtravel stop. Ruger also redesigned the magazine release, magazine disconnect & disconnect spring, and the striker blocker and striker blocker spring.<ref>http://www.ruger.com/SR9Recall/PDF/RecallUpdate.pdf List of changes made to the SR9. Accessed December 10, 2008.</ref> Ruger initially announced that, beginning in mid-May 2008, they would retrofit SR9 pistols having a serial number below 330-30000 with the new parts, and include a spare magazine free of charge (approximately 11,000 pistols). SR9 pistols with serial numbers of 330-30000 and higher were manufactured with the safety enhancements and are not subject to the recall. Ruger began shipping recall boxes to customers in July 2008.<ref name="srr" /> Some of the early SR9 pistols had a different magazine latch and were upgraded to the new style, allowing the use of early and later SR9 magazines.<ref name="gb3"/>

===Discontinuation=== In 2017, twelve years after its introduction, Ruger discontinued the SR-Series of handguns. This was presumably because Ruger wanted to focus on the higher-end [[Ruger American Pistol]] and the cheaper [[Ruger Security-9]], introduced in that same year.<ref>{{Cite web|url=https://ruger.com/news/2017-12-22.html|title = Ruger News}}</ref>

==Design details== [[File:RugerSR9.jpg|thumb|Ruger SR9 with brushed stainless steel slide]] The SR9 is the first large-caliber [[Firing pin|striker]] fired pistol designed and manufactured by Sturm Ruger.<ref name="gb"/> Similar to [[Glock Ges.m.b.H.|Glock]]'s "[[safe action]]", the striker fired SR9 features a [[Trigger (firearms)#Pre-set (striker or hammer)|pre-set trigger]]. With this type of action, the striker is partially cocked when the slide is cycled, then is fully cocked and released when the trigger is pulled.<ref name="gb"/> Due to safety concerns, the moderately long and heavy trigger pull of this type is seen as ideal for law enforcement and self-defense applications.<ref name="gb"/> The SR9 and SR9c have identical trigger groups. Enthusiast website Gunblast rated both the SR9 and SR9c examples it tested with a factory trigger rearward travel at 9.5&nbsp;mm (0.37&nbsp;in). Gunblast rated its SR9 example with a trigger pull of {{convert|30|N|lb-f|1|lk=on|abbr=on}}, and Gunblast rated its SR9c example with a trigger pull of {{convert|23|N|lb-f|abbr=on|1}}. Gunblast's SR40 example was rated with a trigger pull of {{convert|29.5|N|lb-f|abbr=on|1}}. The difference in trigger-pull is most likely due to variances between individual guns, and not to a change in specs by Ruger between the models.<ref name="gb2">Quinn, Jeff. [http://www.gunblast.com/Ruger-SR9C.htm “Ruger SR9c Compact 9mm Semi-Auto Pistol”] Gunblast Web site. Accessed 16 January 2010.</ref><ref name="gb3">Quinn, Jeff. [http://www.gunblast.com/Ruger-SR9-2.htm “Ruger’s Improvements to the SR9 Auto Pistol”] Gunblast Web site. Accessed 16 January 2010.</ref><ref name="gb4"/> The trigger travel is {{convert|7.8|mm|in|2|abbr=on}}.

The SR9 is [[Recoil operation#Short recoil operation|recoil operated]] with a locked breech. It features a [[Magazine (firearms)#Box|staggered column box]] [[Magazine (firearms)|magazine]] (double-stack magazine) with a capacity of 17 rounds, and is also available in a 10-round configuration for locales where capacities are [[Gun laws in California#Assault Weapons Control Act of 1989|restricted]].<ref name="gb"/> The pistol has a very low slide profile; this holds the barrel axis close to the shooter's hand and makes the Ruger SR9 more comfortable to shoot by reducing [[muzzle rise]] and allowing for faster aim recovery in rapid shooting sequences. The slide is available in either brushed or blackened through-hardened stainless steel, and the frame is [[fiberglass]]-reinforced [[nylon]] polymer, resistant to warping or failure.<ref name="gb"/> The frame is offered in black or [[olive drab]].<ref>[http://www.gunsholstersandgear.com/2008/02/04/ruger-sr9-pistol-the-slim-striker-fired-9mm-pistol-from-ruger-now-available-with-od-green-frame/ “Ruger SR9 Pistol: The slim striker fired 9mm pistol from Ruger now available with OD Green frame“] Guns holsters and Gear Website. Accessed December 9, 2008.</ref> The SR9 also has a reversible backstrap which allows the owner to select either a flat or arched grip housing, based on personal preference.<ref name="wg"/><ref name="gb"/> In addition, the SR9 sports a [[Picatinny rail]] for the mounting of [[Laser sight#Laser sight|laser sights]] and [[Tactical flashlight#Weapon mounted lights|tactical lights]].<ref name="wg"/><ref name="gb"/>

[[File:LoadedIndicator.jpg|thumb|Loaded chamber indicator indicating a cartridge present in the chamber of a SR9c.]]

The SR9 has multiple safety devices such an ambidextrous manual thumb safety and magazine release, a [[loaded chamber indicator]], a visual and [[Somatosensory system|tactile]] cocked-striker indicator, and a [[Safety (firearms)#Firing pin block|firing pin block safety]] which prevents the pistol from firing if it is accidentally dropped. The SR9 also features a [[Safety (firearms)#Magazine disconnects|magazine disconnector]].<ref name="wg"/><ref name="gb"/> The Ruger SR9 can safely be dry fired with an empty magazine in the pistol. A Ruger-issued warning states that, due to the disconnector, dry firing the pistol without the magazine inserted will cause unnecessary wear to the striker block,<ref name="gb"/> but published firearms industry information notes that the SR9's disconnect can be deactivated simply by removing some of the disconnector linkage.<ref name="wg"/> Disabling the magazine disconnect allows a chambered round to fire even if magazine is removed. This can be inherently dangerous, given accidental discharge risk. (In tactical terms, it permits a near empty magazine to be ejected and replaced, having a fireable round chambered during exchange, which is useful in many situations) .

The SR9's open [[iron sight]]s are of the [[Iron sight#Contrast enhancements|three-dot]] enhanced contrast variety, and offer drift adjustment on both front and rear blades for [[windage]], as well as rear-sight [[Iron sights#Adjustable iron sights|adjustment]] for [[Elevation (ballistics)|elevation]].<ref name="wg"/><ref name="gb"/>

==Variants== [[File:SR9cwithmag.jpg|thumb|right|The compact version SR9c with blackened stainless steel slide and with factory full-sized magazine shown below. On the magazine is the grip adapter.]]

*The '''Ruger SR9''' started to ship in October 2007. It is the first model of the Ruger SR-series. The full-size Ruger SR9 is chambered in [[9×19mm Parabellum]], and it is shipped with two 17-round, flush-fit magazines and a loading tool. An economy version of the SR9, the '''9E''', was released in 2014. *The '''Ruger SR9c''' started to ship in January 2010, according to Ruger.<ref>{{cite web|url=http://ruger.com/products/sr9c/index.html|title=Ruger SR9c product page|access-date=24 November 2014|url-status=dead|archive-url=https://web.archive.org/web/20141105205135/http://www.ruger.com/products/sr9c/index.html|archive-date=5 November 2014}}</ref> 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, The round-in-chamber indicator eliminates need to press check, also allowing tactile round-in-chamber check—even in complete darkness—by raising forefinger to feel if indicator is in raised position or not.(which is useful in both law enforcement and home defense) (See image)<ref name="gb2" /> The Ruger SR9c was chosen as the Shooting Industry Academy of Excellence's Handgun of the Year in 2010.<ref>{{cite web|title=Shooting Industry Magazine|url=http://www.shootingindustry.com/si9202/hnd9202.html|publisher=FMG Publications|access-date=April 2, 2011|url-status=dead|archive-url=https://web.archive.org/web/20101225060418/http://shootingindustry.com/si9202/hnd9202.html|archive-date=2010-12-25}}</ref> *The '''Ruger SR40''' started to ship in October 2010 to dealers.<ref name="gb4">Quinn, Jeff.

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 {{convert|0.060|in|mm|abbr=on}} wider than the slide of the SR9. According to Ruger, the added mass of the SR40 slide reduces slide velocity during cycling to help reduce felt [[recoil]] and increase service life expectancy.<ref>{{cite web|url=http://www.ruger.com/news/2010-10-12.html|title=Press Release. "Ruger Introduces the SR40." October 12, 2010|access-date=24 November 2014}}</ref> *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 first appeared at the 2013 [[SHOT Show]] annual tradeshow for the shooting, hunting, and firearms industry.<ref>{{cite web|url=http://www.gunsholstersandgear.com/2013/01/04/ruger-sr45/|title=Ruger SR45 By Richard on January 4, 2013|date=4 January 2013|access-date=24 November 2014}}</ref><ref>{{cite web|url=http://www.gunsholstersandgear.com/2013-shot-show/|title=2013 SHOT Show|date=15 October 2012|access-date=24 November 2014}}</ref> It has a capacity of 10+1 rounds.
