The Security-9 managed to be even less expensive than the SR-Series as it eliminated the adjustable backstrap and ambidextrous magazine release, used an internal hammer-fired mechanism instead of a striker-fired mechanism and hardened aluminum alloy rails instead of steel rails. The Security-9 was primarily aimed at the affordable handgun demographic. ## Design The design and internal hammer action of the Security-9 pistol are derived from firearms first produced by [Kel-Tec](/source/Kel-Tec) (such as the [P11](/source/Kel-Tec_P11)) circa 1995. The trigger on the Security-9, despite its hybrid single- and double-action nature, is relatively light. Ruger calls this mechanism the "Secure Action" design, and it combines the trigger pull of the [LCP](/source/Ruger_LCP#Second_Generation) with [single-action](/source/Single_action), as it has a positive reset. It also has a hammer that provides a strong ignition force that has a slide racking to make it much easier to slide. The pistol also features a sight system with drift adjustable rear sight and a fixed front sight. The strong spring tension and a hammer catch help prevent the hammer from contacting the firing pin unless the trigger is pulled. A horizontal pin must be pushed out of the frame in order to separate the slide from the frame. The trigger does not need to be pulled prior to disassembly.[2] The Ruger Security-9, like the [Ruger American Pistol](/source/Ruger_American_Pistol) and the [SR-Series](/source/Ruger_SR-Series), has a polymer frame made out of glass-filled [nylon](/source/Nylon). The Security-9 comes with 15 round magazines and will function with SR-Series magazines. (Ruger also offers 17-round magazines.) Security-9 magazines will also function in the [Ruger SR9c](/source/Ruger_SR9c). The Ruger Security-9 does not have the ambidextrous mechanisms of the SR-Series. However, it has features that the full-sized SR9 did not, including front cocking serrations and a standard [Picatinny rail](/source/Picatinny_rail) for accessories. ## Variants When they were first introduced in 2017, the Security-9 model was offered with 15 or 10 round magazines, and certain models came from the factory with a Viridian E-Series Red Laser on the accessory rail. The pistol is also available with a pre-installed Hogue wraparound rubber grip. In 2019, Ruger introduced the Security-9 Compact. Designed for concealed carry, the Compact model features a shorter slide, shorter barrel, and overall smaller frame. The Compact takes 10-round magazines.[3] Also in 2019, Ruger introduced the Security-9 Pro series. The Pro models are a higher-end version of the standard Security-9 and Security-9 Compact, but feature factory-installed steel [tritium](/source/Tritium) night sights and no manual thumb safety.[4] Ruger also offers the Security-9 in different colors: Davidson's Flat Dark Earth, Black, TALO Turquoise, Sports South Silver, RSR Group Cobalt, Big Rock Sports Coyote Brown, Davidson's Battleworn Flag, Lipsey's Flat Dark Earth Frame(Black slide). ## References 1. **[^](#cite_ref-1)** [The All New Security-9 from Ruger - Secure, Simple, Affordable](https://ruger.com/news/2017-12-22.html) 1. **[^](#cite_ref-2)** ["Review: Ruger Security-9"](https://www.gunsandammo.com/editorial/review-ruger-security-9/247632). 30 May 2018. 1. **[^](#cite_ref-3)** ["An Official Journal of the NRA | Ruger Introduces Security-9 Compact Pistol"](https://www.americanrifleman.org/content/ruger-introduces-security-9-compact-pistol/#:~:text=Ruger%20has%20introduced%20a%20compact,is%20packed%20with%20big%20features.). 1. **[^](#cite_ref-4)** ["Ruger News"](https://ruger.com/news/2019-11-18.html). ## External links - [Security-9 at Ruger official website](https://ruger.com/products/security9/models.html) - [Security-9 Official Announcement Press Release](https://ruger.com/news/2017-12-22.html) v t e Sturm, Ruger & Co.
