Special Features

• The 5.50" cold hammer-forged barrel produces ultra-precise rifling that delivers exceptional accuracy and long-term bore durability across thousands of rounds.
• The 1/2x28 threaded muzzle with included thread protector makes the Mark IV 22/45 (40192) compatible with standard suppressors and muzzle devices without any additional modification.
• The drilled and tapped alloy steel receiver accepts Weaver- or Picatinny-style optic rails, giving shooters a direct path to mounting a red dot or compact scope.
• Ruger's one-button takedown system lets the barrel-receiver assembly tilt free from the grip frame without tools, making field-stripping and chamber-to-muzzle cleaning fast and straightforward.
• Engraved American walnut grip panels in a 1911-style profile give this pistol a distinctive, upscale appearance that sets it apart from standard polymer-grip variants in the Mark IV lineup.
• The 2025 Collector's Series package includes a commemorative plate, decal, and lapel pin, adding collectible provenance to a fully functional firearm.
• An internal cylindrical bolt design maintains permanent sight-to-barrel alignment for higher accuracy potential than conventional moving-slide pistol designs.
• The ergonomic bolt stop and contoured ejection port support smooth, reliable operation round after round.
• A magazine disconnect prevents discharge when the magazine is removed, and the push-button magazine release on the left side of the frame drops the magazine free for fast reloads.

Practical Benefits

• The 5.50" threaded bull barrel makes this pistol an ideal platform for suppressed rimfire shooting, letting you run it quietly at the range or in the field without swapping components.
• The 1911-style grip angle and polymer frame give you a familiar handling feel if you shoot a full-size centerfire pistol, making this an effective .22 LR training companion.
• Two included 10-round magazines mean you spend more time shooting and less time reloading during practice sessions.
• The drilled and tapped receiver lets you mount your preferred optic directly, turning this into a precision-focused rimfire pistol ideal for bullseye or informal target work.
• The Collector's Series presentation adds display and collection value while the pistol remains fully shootable, so it works equally well in a safe or on a range bench.
• Whether you are a dedicated rimfire shooter or a collector building a curated display, the Mark IV 22/45 Collector's Series gives you a pistol worth owning and using for years.

The Ruger Mark IV 22/45 Collector's Series (40192) in .22 LR is a proven platform and a smart addition for the rimfire shooter or collector who demands both performance and craftsmanship in a single package.
