<p>Offering simple one-button takedown in a design built for long-lasting accuracy, the Ruger® Mark IV™ 22/45™ Semi-Auto Rimfire Pistol with Threaded Bull Barrel offers precision performance that's easy to operate. Locked securely in a lightweight, 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 4.4 cold hammer-forged bull barrel features ultra-precise rifling to offer exceptional accuracy, and comes with 1/2-28 threading for a suppressor. A redesign of proven rimfire designs, the Mark IV 22/45 features a simple rear-mounted takedown button and 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 front strap and checkered back strap 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 push-button mag release. Pistol comes with iron sights and is drilled and tapped for a Weaver or Picatinny rail.
