Offering simple 1-button takedown in a design built for long-lasting accuracy, the Ruger® Mark IV™ 22/45™ Semi-Auto Rimfire Pistol offers accurate performance that's easy to operate. Locked securely in a lightweight and comfortable, precision-molded polymer grip frame, the 22/45's internal cylindrical bolt construction ensures permanent sight-to-barrel alignment for higher accuracy potential than standard moving-slide designs. Its 5.5" cold hammer-forged bull barrel features ultra-precise rifling to offer exceptional accuracy that lasts. A redesign of proven rimfire designs, the Mark IV 22/45 features a simple rear-mounted takedown button and a frame-mounted pivot pin to eliminate the complexities of field stripping to make proper chamber-to-muzzle cleaning easier. Checkered, 1911-style grip panels provide a comfortable, non-slip hold along with the serrated frontstrap and checkered backstrap on the grip frame. An ergonomic bolt stop, contoured ejection port, and easy-to-grasp bolt ears allow for durable and reliable operation round after round. Easy-to-use design features an easy-to-use push-button magazine release on the left side. Pistol features iron sights, as well as a drilled and tapped receiver for a Weaver- or Picatinny-style rail.
