The Ruger Mark IV 22/45 offers streamlined functionality and precision in a rimfire pistol designed for ease of use and accuracy. It features a simple, tool-free takedown system that allows the barrel-receiver assembly to pivot off the grip frame with a single button press, facilitating quick field-stripping and thorough cleaning. The pistol's polymer grip frame is ergonomically designed with a serrated frontstrap and checkered backstrap for a secure hold. Its cold hammer-forged barrel delivers exceptional accuracy and durability, while the internal cylindrical bolt construction maintains consistent sight-to-barrel alignment, enhancing precision. The pistol boasts checkered, 1911-style grip panels for both aesthetic appeal and a non-slip grip. The ejection port is contoured for reliable operation, and the easy-to-grasp bolt ears ensure smooth cycling. For added versatility, the receiver is drilled and tapped for Weaver- or Picatinny-style rails, allowing for optic mounting. The ambidextrous manual safety can be modified for left-side use, and the push-button magazine release ensures quick reloads, with a magazine disconnect feature enhancing safety. The Ruger Mark IV 22/45 comes with two 10-round magazines.
