The Ruger Mark I is a semi-automatic pistol chambered in .22 Long Rifle, produced in 1956. It represents an early generation of Ruger’s rimfire target pistols, built with a fixed barrel and internal bolt design typical of the series. The frame and upper receiver are constructed in steel, and the pistol utilizes a single-stack magazine configuration. The overall layout follows the classic straight-line profile associated with the Mark I series, with controls positioned along the left side of the frame for magazine release and safety operation. This pistol is used. It is equipped with a trigger shoe, an accessory that broadens the trigger face to modify finger placement and feel. The Mark I’s design emphasizes precise alignment of the barrel and receiver, contributing to its reputation among early target pistols. The 1956 production date places it within the first decade of Ruger’s rimfire pistol manufacturing, identifiable by the original style grip panels and receiver markings typical of that period. No refinishing or modification details are provided beyond the installed trigger shoe. One magazine is included with the pistol. No additional accessories, packaging, or documentation are specified. The configuration and included components correspond to the standard single-magazine setup found on early Mark I models. This firearm qualifies as a Curio & Relic due to its production era and design lineage within Ruger’s historic rimfire series. Finish is very worn on grip, just below and on trigger guard.
