The NHG RUGER MARK IV 22/45 (Model 18,555) is the definitive rimfire trainer, blending the legendary reliability of Ruger’s target pistol lineage with the world-class ergonomics of the 1911 platform. Renowned for its surgical accuracy and the groundbreaking “one-button takedown” system, this .22 LR pistol is engineered to provide a high-performance shooting experience without the complexity or recoil of a centerfire sidearm. Featuring a 4.4-inch barrel, it strikes the perfect balance between a maneuverable “kit gun” and a dedicated target-grade weapon.

Built on a lightweight, precision-molded polymer grip frame, the 22/45 features an optimized grip angle and control layout that mimics the iconic 1911. This makes it the premier choice for shooters looking to sharpen their tactical fundamentals on a budget. The Mark IV’s signature feature—the recessed button at the back of the frame—allows the upper receiver to tilt up and off for instant, tool-free cleaning, finally ending the “headache” associated with older rimfire designs. With its 4.4-inch barrel providing a generous sight radius, the 18,555 is as at home on the competition line as it is in a backyard range.

A favorite among competitive plinkers, small-game hunters, and tactical trainers, the Ruger Mark IV 22/45 has earned its reputation as the gold standard for “all-day” rimfire fun. Its combination of a 10-round capacity, an ambidextrous manual safety, and a crisp, light trigger press makes it a top-searched firearm for those who demand a dependable, high-performance .22 LR. Whether you’re teaching a new shooter or chasing the perfect bullseye, the Model 18,555 delivers a level of mechanical precision that is simply unmatched in its class.
