The Ruger SR9 started to ship in October 2007.The compact version SR9c with blackened stainless steel slide and with factory full-sized magazine shown below. (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). This is inherently dangerous, given accidental discharge risk. Disabling the magazine disconnect allows a chambered round to fire even if magazine is removed. 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, but published firearms industry information notes that the SR9's disconnect can be deactivated simply by removing some of the disconnector linkage. The Ruger SR9 can safely be dry fired with an empty magazine in the pistol. The SR9 also features a magazine disconnector. The SR9 has multiple safety devices such an ambidextrous manual thumb safety and magazine release, a loaded chamber indicator, a visual and tactile cocked-striker indicator, and a firing pin block safety which prevents the pistol from firing if it is accidentally dropped.

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. Similar to Glock's 'safe action', the striker fired SR9 features a pre-set trigger. The SR9 is the first large-caliber striker fired pistol designed and manufactured by Sturm Ruger.
