At its introduction, Ruger’s Mark IV .22 Long Rifle pistol was offered in two models and three SKUs. The Target model, available in black or stainless, is the all-business, utilitarian descendent of Bill Ruger’s Standard model rimfire. But for American Rifleman’s Joe Kurtenbach, it’s the Hunter model—with its extended barrel, enhanced sights and elegant lines—that truly captures the spirit of Ruger’s original, and capitalizes on the platform’s evolution.
