"The Ruger Mark IV Target California-Compliant Semi-Auto Rimfire Pistol boasts a simple rear-mounted takedown button and a frame-mounted pivot pin that eliminate the complexities of field stripping. This Ruger Mark IV pistol disassembles and reassembles easily, allowing proper chamber-to-muzzle cleaning. A 5.5"" cold hammer-forged barrel has ultra-precise rifling to maximize accuracy and durability. The replaceable nonslip grip panels wrap around the 1-piece, precision CNC-machined grip frame for a precise hold. A fixed front sight combines with the fully adjustable target rear sight to provide an outstanding sight picture, plus the receiver comes drilled and tapped for attaching a Weaver- or Picatinny-style rail. The target trigger breaks crisp and clean. Internal cylindrical bolt ensures permanent sight-to-barrel alignment and higher accuracy potential than conventional moving-slide designs. Contoured ejection port and easy-to-grasp bolt ears promote durability and reliable operation. A manual, ambidextrous thumb safety locks the sear, while allowing the pistol to be loaded and unloaded when engaged. A magazine disconnect prevents the pistol from firing once the magazine is removed. Magazine drops free using a convenient push-button release for efficient reloading. The Ruger Mark IV Target semi-auto rimfire pistol includes two 10-round magazines for compliance with California laws.
