The Ruger Mark IV 22/45 250th Anniversary is a semi-automatic rimfire pistol chambered in .22 LR, combining a precision-oriented target design with the familiar 22/45 grip configuration. Its 4.40″ cold hammer-forged threaded bull barrel and 10+1 capacity make it well suited for recreational and target shooting.
This commemorative model features a blued finish, polymer grip frame, checkered synthetic 1911-style grip panels, and special barrel engraving commemorating America’s 250th year of liberty. A factory-installed optics mount, adjustable rear sight, and Ruger’s one-button takedown system add modern convenience to the proven Mark IV platform.
