Ruger Mark IV 22/45 Lite .22LR

Updated August 24, 2026

This Ruger Mark IV 22/45 Lite semi-automatic pistol is chambered in .22 LR and combines Ruger’s legendary rimfire pistol lineage with a highly distinctive modern configuration. This example features an approximately 5.75" threaded barrel with a shiny bore and presents in very good overall condition. The pistol utilizes the 22/45-style polymer grip frame, designed to provide a grip angle similar to the classic 1911, paired with a lightweight upper assembly finished in an eye-catching blue color with extensive porting and ventilation. Beautiful wood grips further distinguish this example and give the pistol a custom, upscale appearance. A Picatinny rail is installed for mounting optics, and the threaded barrel adds additional versatility. Two magazines are included. Ruger’s Mark-series pistols trace their roots to the company’s earliest firearms and have become some of the most successful American rimfire pistols ever produced. With its blue Lite upper, wood grips, threaded barrel, optics rail, and two magazines, this is a particularly handsome Mark IV package. Please see photos.
