The Ruger Mark IV™ 22/45™ Pistol (Model 40190) is the ultimate .22 LR handgun for sport shooting, plinking, and target practice. Engineered for shooters of all experience levels, this semi-automatic pistol combines classic 1911 styling with modern polymer frame innovation, delivering comfort, durability, and consistent accuracy round after round.

Firearm Features

  • Simple One-Button Takedown: Effortlessly field-strip the pistol without tools—just press the rear frame button and tilt the barrel/receiver assembly up and off the grip frame for fast, thorough cleaning and maintenance.
  • Threaded Bull Barrel: 4.40" cold hammer-forged, 1/2"-28 barrel with thread protector allows easy attachment of popular muzzle accessories (suppressors, compensators), enhancing versatility on the range.
  • Precision Polymer Grip Frame: Ergonomic, molded polymer frame with serrated frontstrap and checkered backstrap ensures a secure, non-slip hold in any condition. Checkered 1911-style synthetic grip panels add both style and stability.
  • Adjustable Rear Sight & Picatinny Rail: Fine-tune your point of aim with the adjustable rear sight, and mount red-dot optics or tactical lights instantly on the factory-installed Picatinny rail for rapid target acquisition.
  • Reliability & Accuracy: Internal cylindrical bolt construction maintains permanent sight-to-barrel alignment for superior accuracy potential, while the contoured ejection port and robust bolt ears guarantee smooth, reliable cycling.
  • User-Friendly Controls: Ambidextrous manual safety (convertible to left-side only), convenient push-button magazine release, and magazine disconnect safety feature provide secure, intuitive operation.
