==History== Introduced in late 2017, Ruger intended to use the Security-9 to replace the [[Ruger SR-Series]]. 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]] (such as the [[Kel-Tec P11|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 [[Ruger_LCP#Second_Generation|LCP]] with [[Single action|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.<ref>{{cite web | url=https://www.gunsandammo.com/editorial/review-ruger-security-9/247632 | title=Review: Ruger Security-9 | date=30 May 2018 }}</ref>

The Ruger Security-9, like the [[Ruger American Pistol]] and the [[Ruger SR-Series|SR-Series]], has a polymer frame made out of glass-filled [[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]]. 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]] 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.<ref>{{Cite web|url=https://www.americanrifleman.org/content/ruger-introduces-security-9-compact-pistol/#:~:text=Ruger%20has%20introduced%20a%20compact,is%20packed%20with%20big%20features.|title=An Official Journal of the NRA &#124; Ruger Introduces Security-9 Compact Pistol}}</ref>

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]] night sights and no manual thumb safety.<ref>{{Cite web|url=https://ruger.com/news/2019-11-18.html|title = Ruger News}}</ref>

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).
